How to check an automatic transmissions condition.

Automatic Transmissions: Fluid Fill

Automatic Transmissions: Fluid Fill

As automatic transmissions become more reliable these days, it’s still easy to break and very expensive to fix part of the vehicle.

If heavily abused, the automatic transmission can be easily destroyed within just half an hour. For example, a friend of mine had burnt the automatic transmission up in 20 minutes when he was trying to free his shiny Audi from the snow in the next day after he bought it! It cost him about $3000 to rebuild it and after one year it broke down again.

Also, an automatic transmission is very sensitive to the transmission fluid quality and condition. Improper fluid type can damage the transmission. A person I know added a gear oil (oil for manual transmission) into the automatic transmission, guess what, 30 minutes of driving was enough to kill the transmission.

Obviously, when buying a used car, the automatic transmission is one of the most important parts to check. I have already described a few signs that may indicate potential transmission problem in a used car. In addition, I strongly recommend to have the used car inspected by a mechanic before buying it, it will well worth it.

I have a friend who bought a fairly new Honda Civic that seemed to be in great shape. It has low mileage, about 35,000 on it and drove great on the road test. Basically it looked like a great buy. He got a good deal on it and decided against buying an extended warranty. One that would cover major failures like the transmission or engine, or any part of the power-train.

Low and behold about 2 months out of the short warranty he received, the transmission had a failure. I’m not going to drag this out, but this time he took my advise. You see when I recommended the extended warranty, he decided against it. Too late now. Now he decided to listen to me.

After the great battle between him and the dealer, which was a short battle, it was time to choose the right replacement transmission. With that he took my advise and called GotTransmissions.com. After speaking with a representative he chose to buy a used transmission. It’s been a few months and he is a happy camper with his low mileage used transmission. Call us @ 866-320-1182.

Manual Transmissions, Nascar Style..

Jerico Manual Transmissions

Jerico Manual Transmissions

Winning races demands preparation, durability and the performance to be in a winning position when it counts. Jerico’s WC4-4 Super Duty manual transmissions, the product of over 25 years of experience, research and brutal real-world testing provides the edge you need — and the peace of mind you want.
Jerico’s WC4-4 was designed from the ground up, not adapted from an existing flawed design. Jerry Hemmingson, founder of Jerico, and the hands-down leader in transmission innovation, took out a clean sheet of paper and designed the WC4-4 as he knew it should be.
Working within the dimensional limits of the rules, Jerry began by positioning the major components to eliminate misalignments found in nearly all previous designs. These small but crucial misalignments were responsible for binds, frictional losses and accelerated wear that reduced performance and initiated premature failures.
The mainshaft size was increased, virtually eliminating problematic flex. Top quality caged bearings were added throughout, including caged roller bearings on the thrust faces of all gears. Horsepower previously lost to inter-gear friction is now passed through to the rear wheels. A caged bearing was added at the rear of the input shaft to regain horsepower previously expended turning unused gears. Even the cluster gear rides effortlessly on two one-inch caged bearings.
The tailshaft is completely supported by a premium-caged bearing located in a CNC machined boss in the tailhousing. This additional feature prevents transmitting damaging movement and vibrations to the driveshaft and rear end.
The WC4-4 front bearing cover and throwout sleeve are CNC machined from billet steel for strength and accuracy. A large front bearing behind the cover helps withstand the rigors of racing and drivers launching the car from often uneven pits stalls.
All Jerico gears are machined from VAR (Vacuum Arc Remelt) steel, hot rolled specifically for Jerico. To absolutely ensure the finest quality steel, Jerico buys entire special runs directly from the mill. This represents a huge expense, but it is the only way to guarantee the finest quality material.
Each gear is extensively CNC machined to ultra-precise tolerances according to our straight cut design that has proven to be without peer in the market. When machining is completed, each gear is precisely heat treated, and then drawn back in our own ovens. Each batch of gears is subjected to multiple high-accuracy tests to assure proper hardness is attained.
Jerico’s dog and slider shifting system, another proprietary design, provides clean, smooth, positive shifts. Whether leaving pit road, grabbing a gear at Pocono, or negotiating a road course, Jerico’s proven dog and slider shifting mechanism is without any substantial competition.
The Jerico WC4-4 comes with an ultra-strong, lightweight case made from A206 aluminum allow, the strongest available. Though difficult to obtain and machine, Jerico Accepts no compromise.
Over 200 gear ratios are available, including overdrive to .85. Ratios can be ‘tuned’ as is necessary for leaving pit road or getting a jump on restarts. Whatever the track, Jerico can build a transmission for the job.
In today’s racing, there is no room for compromise. Your team demands the very best transmissions available — Jerico. For the highest durability with the least rotating weight, internal friction and horsepower loss, Jerico is the only way to go. Anything else is a compromise. GotTransmissions.com @ 866-320-1182

Chrysler TF 604 Transmission Rebuild

Pictures of the inside of one of Chrysler Transmissions called a TF 604. It is a transaxle to be more accurate. Which is what we call front wheel drive transmissions. Enjoy.

If you click on the picture it will enlarge.

The pictures above are of a disassembled TF 604 transmission out of the 2003 Chrysler Town and county van I am rebuilding the transmission on. These are called sub-assemblies. Sub-assemblies are small components in themselves inside the transmission working in harmony together.

Each sub-assembly will be disassembled in entirety and rebuilt. At the point each sub-assembly is disassembled and laid out I will take detailed pictures of each sub-assembly with an understandable explanation.

As I proceed you will get more detailed internal pictures of the process. This is presented by GotTransmissions.com as a courtesy, not for you to go out and rebuild your transmission. If you need a replacement transmission call a professional. GotTransmissions.com @ 866-320-1182.

Nissan 300ZX Clutch and Manual Transmission/s.

Manual Transmissions for Sale

Manual Transmissions for Sale

The clutch in a 300ZX is your standard everyday clutch, nothing special. All non-turbos and 84-86 turbos have 240mm Nissan clutches. The 87-89 Turbos have 250mm Nissan clutches. All are hydraulically operated in the normal fashion. If you are going to replace your clutch setup, buy a quality clutch kit (this means a new oem one). Replacing the manual transmissions gear lube is a good idea and convenient at this time.

Replacing the hydraulic actuation equipment should be part of the job. The hydraulic parts are subject to wear as well since they are hydraulic, a slave cylinder and master cylinder. The rubber components wear out too, so get off the jack and repair the whole system at the same time, it is really cheaper and definitely more efficient to take care of it now.

There are many aftermarket clutches for 300ZXs, some can get very expensive very fast. Racing clutches are highly recommended for modified turbos, for non turbo charged everyday cars buy a brand new OEM, original equipment clutch, which are available now from most automotive parts stores. The original equipment clutch manufacturers now offer the exact same clutches they sell to the factories, to the public via auto parts stores. Very affordable too.

You’ll need an alignment tool, a clutch kit of course that includes a throwout bearing. You would also be advised to have the flywheel surface machined at the machine shop, replace the rear main engine oil seal, and all of the clutch hydraulic components. The only non-common tool you’ll need is a pair of inside snap ring pliers for shift lever on non-turbo models.

Drain the transmission gear lube and refill it with the factory recommended synthetic gear lube. Synthetic is the keyword here. Make sure the transmission has no leaks, if it does have them fixed. Beats needing a replacement manual transmission.

Good luck, we present this info as a courtesy. We are a full service transmission supply company. Call GotTransmissions.com now for all of your transmission need. 866-320-1182.

Dodge and Chrysler TF604 Tranmsissions, are they the same?

Lets Put a Wrench on This Transmission.

Lets Put a Wrench on This Transmission.

I drove the Caravan, actually it is a Town and Country Van, to my buddy’s repair shop and borrowed his Snap On scanner. BTW: one of the vans is made by Dodge and the other one is a Chrysler, respectively, although mechanically they are identical. Anyway it has a 3.8L engine and the Chrysler TF 604 transmission.

It takes a few minutes to input the vehicle identification number into the scanner and get it setup for the exact model vehicle being tested. In this case I have to do a road test. The reason is that the scanner tool will literally pick more usable information about everything internal and all electrical functions during a short 5 minute road test.

For guys like me, this is a very cool and fun thing to do, what can be better than a scanner friendly car? And the Dodge and Chrysler transmissions are just that, the most scan tool friendly car in the world.

After my road test, I was able to examine the information the scanner collected. I want to make a point here, I do not monitor the scan tool while I drive. I go through the standard process necessary for the scan tool to gather the information. The scan tools I use gather info and save it while I drive.

The information showed no electrical issues to be concerned with, but it did show a very high CVI number for the 1-2 clutch pack. What is a CVI number, CVI is an acronym for clutch volume index. CVI is a measurement of how much transmission fluid enters a clutch pack to make it operate, if the number is to big or to small, or out of range (OR), it means the clutch pack is damaged.

A high or low CVI number on any clutch pack means that the transmission has an internal problem. My neighbor has approved a removal and dis-assembly, which is called an RDI. RDI is an acronym for remove, dismantle, inspect.

Once the transmission is removed, I will tear it down, clean it up like I was preparing for brain surgery and inspect the components for damage. I am going to document the whole process with pictures and present them to you as I go.

Remember, this is being presented by GotTransmissions.com, the best transmission replacement company in the continental USA. Our secret to success is providing a good education to our customers. By doing so, we know you will make a better decision on buying replacement transmissions. Call us at 866-320-1182 Now.

2003 Dodge Caravan Transmissions

Transmissions for sale 2003 Caravan

Transmissions for sale 2003 Caravan

One of my old customers called me the other day and asked me if I wanted to check out his transmission in his 2003 Dodge Caravan. OK, no problem, but you gotta leave it with me so I can diagnose it. The thought of diagnosing and possibly repairing his transmission was very exciting to me. I have not really done any of this type of work since I sold my transmission shop of 26 years 4 years ago this month.

In reality, I am more in touch with what is going on in the technical side of the transmission world now, because I am not working and dealing with issues related to operating a shop. First off we talked about diagnosis and it’s importance. I told him that the TF604, which is the transmission in his vehicle was very scanner friendly and I can exact more information out of this transmission than practically any other transmission made.

The problem with his transmission is called a 1-2 shift slide /bump. A common problem with this transmission. Without going into the intimate, deep details of the process, we can figure out why the engine light is on and if it is the transmission. We can perform tests that would be the equivalent of a blood test, x-rays, MRI, cat scan on a human. The point is that when I’m done with the scanner part, I will have an intimate relationship with the transmission.

Because the van has about 85,000 miles on it, while the fluid is clean now, when it was changed last year, it was noted on the ticket that there was significant contamination in it. If this is so, there may be some internal issues to deal with. We will know if it is necessary to remove the transmission for repairs or rebuild, or whether we can install an update kit and solve this issue with the transmission in the van, at reasonable cost, soon.

Of course he is worried about the possibility of needing a rebuilt transmission. That is a reasonable concern that needs addressing. What I told him was we can’t make any decisions until my diagnosis is in. If the trans. needs to be removed to be repaired and it ends up that a replacement transmission is needed, I flat out told him that GotTransmissions.com was the place to buy it.

With that in mind, we will carry on with the diagnosis, when we have all of the evidence in, a decision can be made. I mentioned to him that he can choose from used transmissions with really low mileage or transmissions with all of the updates we discussed. What we know for sure is that the phone number to call is 866-320-1182. To be continued.

Transmissions Affect Fuel Economy.

Transmissions that grip like an alligator

Transmissions that have grip of an alligator

Choosing a fuel-efficient automobile was a whole lot simpler 30 years ago, the last time the U.S. was in the grips of a gasoline price crisis. It was often as simple as buying small vehicles with manual transmissions. Not he stakes are much higher regarding your transmission choices.

Today, with gas prices soaring to new record highs almost weekly, finding fuel economy means navigating an almost bewildering selection of vehicles, modern automatic transmissions and computerized intelligence. Even enormous SUVs can qualify if they come equipped with gasoline-electric hybrid drive systems.

Behind this tremendous hike in choices — to a fairly significant extent, experts say — has been a concomitant increase in the variety of transmissions.

Whereas in the 1970s there were only four- and five-speed manual transmissions and three- and four-speed automatic transmissions, now there are six-speed manual, six-, seven- and eight-speed automatic, six- and seven-speed “dual-clutch” automatic-manual, and continuously variable transmissions.

The result: more efficient engine operation and higher fuel economy in every car, whether it’s a high-performance Porsche Carrera or a modest Volkswagen Jetta.

But there are important differences among these sophisticated transmissions, including in how much they contribute to better fuel efficiency. Knowing those differences may help you the next time you’re in the market for a new car.

The whole point of the transmission is to allow the vehicle’s engine to operate at its most efficient state under all conditions and demands.

Gear ranges help do that by matching the engine’s speed, or RPM (revolutions per minute) and torque – or pulling power – to the demands of acceleration. Lower gears provide less speed but more torque to get the vehicle’s mass in motion, whereas higher gears provide more speed, but less torque, to keep things rolling along.

The engine is at peak efficiency at only one point as its RPMs climb through each gear range, so as more gears or “speeds” are added to a transmission, the more high-efficiency spots are available and the more efficient the engine’s overall operation.

Transmission specialists at General Motors, Ford and Chrysler say 6-speed automatic transmissions will yield a four to six percent fuel economy improvement compared to 4- and 5-speed automatics.

The transmission Specialists at GotTransmissions.com are prepared to help you sort out the particular replacement transmission that is in your best interests. For most folks this is an overwhelming task to handle, trust us, our success is dependent on your success.

Make Your Clutch and Manual Transmissions Last Longer.

Learning to drive manual transmissions can instill a lot of anxiety. Everyone thinks it is so hard to do and that they will be so embarrassed in front of other people while learning to drive a stick shift. It is mildly challenging, but worth the anxiety it creates? No. Basically, the car will not become damaged. The only item worth be concerned about is the clutch, which this video explains and demonstrates in a short and understandable way. Which is why I chose it. Go ahead and watch it.

The biggest concern for any standard or manual transmission owner is the clutch. An inexperienced driver can ruin a clutch in no time, literally. An experienced driver with a friendly clutch foot can get over one hundred thousand miles out of a clutch, with ease. Proper teaching methods are a good idea for beginners drivers.

For technical reasons I won’t get into, one of the things I think is very important is to put your car in neutral at a stop light, with the clutch pedal out or disengaged. As opposed to sitting at the stop light with the transmission in 1st gear and the clutch engaged and ready to go when the light changes. This puts undue stress on the throwout bearing, causing pre mature wear and throwout bearing failure.

For all practical purposes, you can avoid clutch problems using a logical and realistic driving approach. For beginner drivers, simply Google, ”learn to drive videos”, believe me, there are plenty to choose from. If you have any questions at all about manual transmissions or automatic transmissions, don’t hesitate to Call us @ 866-320-1182. You can speak with a qualified professional and get the answers you need to all of your transmission questions. GotTransmissions.com

Automatic Transmissions And Horse Riding..

Our Transmissions work like a horse

Our Transmissions work like a horse

What do automatic transmissions have in common with horseback riding? No much. The thing that comes to mind is both automatic transmissions and competitive horse jumpers both operate in a smooth effortless manner. The smoother and more effortless the better.

Both horses and transmissions need at a minimum, adequate care, although above average care works much better. A well fed and cared for horse will outperform an old gray mare getting fed tons (literally) of grains instead of being pasture raised. Not only that, it will outlive and have a better life than a horse that is ready for the glue factory. Which is animal abuse and we don’t support that here.

A properly maintained automatic transmission works in an efficient and effortless manner to the person who gets in the car and takes off. Usually, people like that never even think about what a marvel of engineering a transmission is, or have any thoughts about this unreal piece of machinery until it needs a maintenance or has a problem.

Care, smoothness and grace are the common denominators between a transmission and a riding horse. Nearly everything lasts longer and runs better with care and the right fuel. Grain fed horses may be fatter for processing and selling to the public for food, but pasture raised horses are healthier and perform at a higher level on the race track.

A transmission that is fed conventional transmission fluid rather than synthetic transmission fluid is like a horse being fed grains, simply put, not as healthy and sturdy for work purposes as pasture raised animals.

The point is that much like a race horse, car transmissions need care in order to perform it’s best and live as long as possible. Caring for your transmission will also keep it invisible for the most part, on top of shifting it’s smoothest.

ZF 8-Speed Automatic Transmission

Thumbs up for ZF Transmissions

Thumbs up for ZF Transmissions

Long known for its excellent passenger car automatic transmissions, ZF has designed another top notch transmission, its all-new 8-speed automatic transmission named as a 2010 Automotive News PACE Award (http://cmprsa.com/PACEAwards/tabid/81/Default.aspx) finalist.

The ZF 8-speed automatic made its debut in the BMW 5 Series Gran Turismo and 760Li, and will also appear on the Bentley Mulsanne and Rolls Royce Ghost models. This all-new design shifts in milliseconds, is similar in size to a 6-speed automatic but with fewer parts, and improves fuel economy by 14 percent over 5-speed automatic transmissions and 6 percent over 6-speed automatics from ZF.

The modular design allows for integration into hybrid vehicles, simply by replacing the torque converter with an electric motor, resulting in a fuel economy improvement of approximately 25 percent.

“It is truly an honor to have our 8-speed transmission recognized as one of the industry’s best innovations,” said Dr. Gerhard Wagner, Member of the Board of Management, ZF Group. “We congratulate the entire development team for their commitment to developing technology that is dynamic, safe and efficient. We believe this is a watershed product that will usher in the next era of automatic transmissions.”

When designing the 8-speed automatic transmission, ZF engineers were not concerned with using a specific number of gears. Instead, the goal was to develop a new transmission that improved fuel economy by at least 6 percent over the current-generation of 6-speed automatic, while also improving the power-to-weight ratio, shift speed and quality, while increasing torque load.

Looks like another winner and transmission designed to further fuel mileage by making existing components more efficient. ZF is always on the ball, which is why they are an industry leader for over 40 years. We sell plenty of used and transmissions for all sorts of foreign and american made vehicles.

Why, because they are terrific transmissions, used in so many brands of cars for so many years that there are lots of good used transmissions available for sale and premium transmissions with all of the current updates installed.
