Transmission Choices Catching Up To Engine Options

Choose your Transmission....

Choose your Transmission....

An extraordinary yet subtle change is taking place in modern cars. For the first time I can think of automakers are providing as many transmissions as engine choices. The new BMW 6-Series, for example, offers just one V-8 engine, but buyers can choose from a 6-speed manual, a 6-speed automatic, or a 6-speed electronically-shifted manual transmission.

Order an Audi A4 and depending on engine, take your pick from a 5-speed manual, 5-speed automatic, 6-speed manual, or gear-less CVT (continuously variable transmission). Even some of the economy cars now let you select from more than the basic 5-speed or 4-speed menu. Ford’s Focus comes with a choice of 5-speed manual, 6-speed manual, or 4-speed automatic.

What’s behind this proliferation of transmissions? It’s partly a matter of matching engine power with gears in order to obtain the best combination of fuel economy and performance. The change also comes as a result of manufacturers experimenting with radical concepts like CVT while backing their hunches with conventional systems because consumers are slow to accept ideas that don’t conform to traditional driving experiences. And finally, there’s the age-old game of segmenting markets to attract more customers.

One wonders if all this is really necessary. While enthusiasts may understand the differences the average car buyer is merely confused and wants nothing more than to put the gear lever in drive, motoring away without giving a further thought to the transmission.

For the most part, that is how I feel. Unless I’m in my 1970 Porsche 911 with a manual 5 speed transmission, I don’t want anything to do with a shifter. That one thing we still have in america, the power to decide on which transmission to choose.

The biggest issue with so many choices in transmissions to make is which transmission is suitable for you and your budget. More importantly is the possibility of needing a replacement transmission. Dealing with a well trained professional can be the difference. You don’t want to deal with a bunch of wino’s dragged off the street to be ”engine replacement specialists” for the day? Do you?

When you become involved in the world of buying transmissions for replacement purposes, it is easy to understand why the outfit you choose is critical for success. Call GotTransmissions.com @ 866-320-1182 and let us do the dirty work. Our goal is to get the right transmission to you as fast as legally possible. Call us today.

Understanding Automatic Transmission Torque Converter Part-2

Torque Converters for Automatic Transmissions

Torque Converters for Automatic Transmissions

Lets pick up where we left off from torque converters part-1. As for stall speed, a torque converter to automatic transmissions is like a clutch to a manual transmissions. Imagine when a clutch is fully released, and you get all the power from the engine. That’s stall speed. A 2,500 stall speed doesn’t mean you need to rev the motor to 2,500 rpm for the vehicle to move. What it does mean in this case is 2,500 rpm is the limit at which the converter will hold back the engine speed if transmission output is prohibited. By disallowing further gain, the increase in engine rpm “stalls.” The speed at which stall occurs with a given converter is a function of engine-peak torque.

You can roughly check your converter’s stall speed by putting the car in Drive, pressing firmly on the brake, and depressing the throttle fully for a couple of seconds. Stall speed will be the maximum rpm shown on the tach. Of course, the tires may spin, as the engine will likely overcome the brake system’s ability to hold them back. This method is referred to as brake stall speed, which is lower than true stall speed, but it’ll get you close enough, though it’s not recommended.

These are four different stators used in the 245mm converter to alter stall speed and torque multiplication. Dozens of different stall speeds can be achieved by using the right fin angle on the bowl and the right stator combination. Experience will allow the builder to select the right combination based on the particulars of your car and its intended use.

A number of factors should be taken into consideration to determine what stall speed is suitable for your high performance project, such as engine-peak torque, the shape of the engine-torque curve, vehicle weight, rear-end ratio, and cam specs. Weight and resistance has a great bearing on stall speed.

For instance, a 2,500-rpm stall speed converter in a T-bucket (light in weight) will probably stall around 1,800 rpm, but put the same converter in a heavier pickup truck and that will ”stretch” it to around 2,800 rpm.

The maximum amount of torque multiplication is dependent on the size and geometry of the blades in the turbine and stator, and it’s generated only when the converter is at or near the stall speed. There will always be a trade-off between maximum torque multiplication and efficiency. High-stall ratio converters are usually relatively inefficient below the coupling speed, whereas low-stall ratio converters tend to provide less possible torque multiplication.

While torque multiplication increases the torque at the turbine output shaft, it also increases slippage inside the converter, raising the fluid temperature and reducing overall efficiency. This is why the internal parts and characteristics of a converter must be matched to the intended vehicle’s specs. It should be noted that lower stall converters (for towing purposes) limit internal heat production, the biggest killer of any transmission.

Heat isn’t the only cause of failure, though, and sudden applications of power in high-horsepower vehicles can break the stator clutch or deform or break the turbine or pump blades. Prolonged excessive loads, very high rpm, or hard launches can distort, or balloon, the housing, even rupturing it in extreme cases.

One aspect of converters we haven’t talked about so far is sizing. let me attempt to explain why some converters are larger than others and how two different-size converters can have the same stall speed.

Two different-size converters can have the same stall speed, but their efficiencies will vary greatly. A converter pump will tend to have a higher efficiency when its blades have a positive angle to them, as this feeds the most fluid to the turbine. The more fluid you feed the turbine, the harder it pushes on it and the more torque is delivered to the transmission.

That’s about it on torque converters without lock up. You can only imagine by reading part-1 and part-2 about torque converters how precise they are and the training and equipment to rebuild them. We want you to feel comfortable buying transmissions from us, education is the key. Need more information? Call us now at 866-320-1182, GotTransmissions.com

Manual Transmissions versus Automatic Transmissions?

Buy Transmissions for Sale

Buy Transmissions for Sale

Both manual transmissions and automatic transmissions, effect and enable movement, momentum, effecting starting, stopping, accelerating, maintaining speed (faster/slower) and reversing of automobiles for example (in our case). Various components work closely together to make this process possible. There components are important individually and collectively to make the transmission (regardless of type) function optimally. Components like the flywheel, pressure plate, clutch plate, release bearing, control linkages and the transmission (manual in this listing case), to engage and disengage power from the engine and enable the above-mentioned processes and outcomes.

Most people argue for manual transmissions and vehicles due to the enjoyment and empowerment they feel by the ‘control’, or hands on fun experience they have, shifting the gears by hand. Some still contest that the manual transmissions still have more of a sense of reality of drivability and driving skill, all in all more spirited to drive. Others position their argument to say that they are cheaper to buy and maintain, and offer improved performance and fuel economy when compared to automatic transmissions. This might have rung true a while ago, but not so much anymore, complexity of units and/or budgets, the gap is much closer now.

There are buying guides available online, that contains all the cars available with manual transmissions. Some drivers, car owners and industry die-hards will continue to swear by the manual transmission for a while to come. With all of the advancements and automatic transmissions with 5, 6 and now 7 forward speeds, controlled by extremely interactive computer systems, it is nearly impossible not beat an automatic with a stick.

Even Porsche has a 7 speed automatic transmission that can be shifted manually and posts the same track times the 8 speed standard model does.

The choice then comes down to your enjoyment and personal preferences. With the exception of sports cars, and we have an exception with the Porsche 7 speed automatic, you have to make the choice.

Yes, the choice has to be yours, but we can help out by providing the type of information you need to make an informed decision. If making a decision on replacing a transmission has to be made, let us provide you with the type of information you need to make your best decision. GotTransmissions.com @ 866-320-1182.

Honda H4A Transmissions on Sale Cheap

Honda Transmissions for Sale

Honda Transmissions for Sale

The H4A Honda Transmissions were a modified version of Honda’s first 4-speed automatic transmission, the H4. Introduced in 1990 on the flagship Honda Accord, the H4A series had three shafts, rather than the two found on the H4.

Since the engine and transmissions mount from left to right instead of north to south, we call this setup a transverse engine and transmissions setup. This is also sometimes called an east-west engine. Most modern front wheel drive vehicles use this engine orientation except for a very few.

Honda automatic transmissions differ from other styles of automatic transmissions in design. It is still hydraulic, as all automatic transmissions are, yet it uses a unique gear train setup, which is different from the usual planetary gears setup the vast majority of automatic transmissions use.

Would you believe that the Honda transmissions are so well engineered and reliable that, literally, Acura uses Honda transmissions. One difference, since this is a transverse setup, the Honda engine is mounted on the right side with the transmission on the left side, and the Acura is mounted exactly 180 degrees different.

The rebuilding process of Honda transmissions is critical and precise. Every component used in the rebuild kits of choice has to come from the dealer, factory original parts are the only ones that allow this transmission to work properly. Aftermarket parts don’t meet the requirements.

Remember, when I say factory parts, I also mean using genuine factory only transmission fluid in your Honda transmission. It is the only fluid blended to work in your Honda transmission properly and give you perfect shifts and long life.

Needless to say, we include a rebuilt torque converter with the rebuilt transmission. The most important part of buying a rebuilt transmission is using a company that does not cheat. It serves no-ones best interests to buy an inferior product that has constant warranty problems and fails shortly out of warranty.

You can make the final call, but we will supply all of the transmission information you need to make the best possible choice for your concerns. If you want to speak with a sales staff member, give us a call at 866-320-1182 and ask us you toughest question. We will give you an honest answer. GotTransmissions.com

Tremec T56 (MM6) Manual Transmissions

Tremec T56 Manual Transmissions For Sale

Tremec T56 Manual Transmissions For Sale

These six-speed manual transmissions are known throughout the industry for its ability to withstand extreme torque loads such as those demanded by the Corvette’s LS1 and LS6 engines, as well as rigors of competition driving. Nevertheless, it’s an extremely flexible unit. In addition to outstanding strength, the use of six speeds offers a wide range of ratios, allowing for a tall first gear for outstanding off-the-line acceleration, as well as over-driven fifth and sixth gears for a high top speed and good fuel economy while cruising.

Blocker rings are an intermediary buffering part between the synchronizer sleeve and the gear cone. When the synchronizer sleeve slides over, it first pushes the blocker ring against the gear cone, and the blocker acts as a cone clutch to help speed up or slow down the gear to the desired speed prior to the synchronizer sleeve sliding over further to engage the gear.

These rings now use a carbon friction lining material, which is more resilient and offers improved high-energy performance. This allows the gearbox to better withstand aggressive shifting and leads to a longer life under typical high performance circumstances.

The T56 was developed as a higher-torque evolution of the well-proven T5 five-speed used in the Pontiac Firebird since 1983. The T56 made its debut with the 1993 Firebird. The unit first appeared in the Corvette in 1997 as part of the introduction of the C5 with the LS1 engine.

The T56 is available in crate form allowing hot rodders and gear-heads to install a 6 speed transmission in older cars , thus improving gas mileage and decreasing engine wear. Also very popular with muscle car owners, helping the cars to take advantage of 2 more forward speeds than what was available in the 60’s.

Regardless of your reasons for needing a Tremec T56 manual transmission, we can serve your best interests. Our inventory includes, rebuilt units, used units and generic units, all ready for shipment.

What is an Automatic Transmission Torque Converter Part-1?

Torque Converters for Automatic Transmissions

Torque Converters for Automatic Transmissions

If there were a vote for the most misunderstood automotive component, we’re willing to bet automatic transmissions would rank pretty high, and the torque converter itself possibly higher still. OK, so it’s kinda like a clutch for an automatic, but how does it work? And, what do stall speed and lockup mean, exactly? How do you choose the ideal torque converter for your project or driving style?

Lets start with the basics of how a converter works. It is essentially a modified fluid coupling that, like a clutch, allows the transmission to be disengaged from the engine, so the latter can still run while the car is stationary but allows power to be transferred when the car is in motion. Unlike a regular fluid coupling, however, a torque converter multiplies torque when there is a difference between input and output speed, similar to a reduction gear.

A torque converter consists of three major internal components: the pump, turbine, and stator, as well as transmission fluid. The housing of the converter is bolted to the engine’s flywheel, and the fins of the pump are attached to the housing. This is a centrifugal pump, throwing fluid outward as it spins. This creates a vacuum that draws more fluid in at the center. The fluid then enters the turbine, which is connected to the transmission via the output shaft, so the trans starts to move the vehicle when the turbine starts to spin.

When the fluid exits the turbine, it is moving in the opposite direction to that of the engine and the pump. It is the function of the stator, which is located in the center of the torque converter, to redirect the fluid before re-entering the pump. The stator is mounted on a fixed shaft but has an internal one-way clutch, since it is required to freewheel at certain operating

A torque converter has three stages of operation: stall, acceleration, and coupling. Stall is when the transmission is in gear, but the brakes prevent the car from moving. At stall, the torque converter can produce maximum torque multiplication, called stall ratio, if sufficient input power is applied.

The acceleration stage sees the car moving but a relatively large difference between pump and turbine speed, where the converter will produce torque multiplication that is less than what could be achieved under stall conditions.

Coupling is when the turbine reaches roughly 90 percent of the speed of the pump. There is no more torque multiplication, and it would be at this stage when a lockup clutch would kick in. Lockup converters have an internal lockup clutch that will lock the two halves of the torque converter together, eliminating any slippage where the engine and trans cannot physically operate at the same speed. This, in turn, eliminates any wasted power and so improves fuel efficiency by as much as 65 percent.

Part-2 about torque converters coming soon, stay tuned in. Don’t forget that GotTransmissions.com includes a rebuilt torque converter with every one of the transmissions for sale. Call us at 866-320-1182 and find out more about our top quality replacement transmissions.

TorqShift Ford Truck Transmissions

Ford Transmissions: Get Geared Up Folks.

Ford Transmissions: Get Geared Up Folks.

The newest one of Fords automatic transmissions is the Torqshift 5-speed 5R110 transmission which replaced the 4-speed (4R100) in the 2003 model year truck along with the new (at the time) 6.0 L diesel engine. The TorqShift Ford transmission design in fact has six forward ratios, but only five are advertised, with the ‘hidden’ gear only used in extreme cold weather.

The TorqShift gear ratios 1st gear through 5th gear (overdrive) are 3.11, 2.22, 1.55, 1.00, and 0.71:1. It also utilizes a computer commanded 4th gear and overdrive can be activated in 2nd gear or 3rd speed. The hidden gear ratio is 1.10:1, used under cold start conditions to aid engine and transmission warm up.

On the TorqShift, once the Tow/Haul mode is activated it can help increase a driver’s control when towing large loads up and down steep grades and automatically minimizes shifts and maximizes available torque. Upon descent, the Tow/Haul mode utilizes engine braking to help extend brake life and improve driver control. An adaptive shift function monitors the TorqShift’s performance over its lifetime, and adjusts shift pressures in real time to assure consistent shift feel and compensate for wear.

For ease of maintenance, the TorqShift’s oil filter is a spin-off style, mounted on the passenger-side exterior of the transmission. Also the TorqShift’s larger fluid lines and a larger transmission oil cooler help to assure cooler operating temperatures, even under the most demanding conditions.

Ford put together a complete system for maximum transmission life, taking a lesson from their full sized work trucks. The transmission is programmed for maximum shift quality and subsequent durability. Proper maintenance is it’s best friend, otherwise it is well prepared from the factory.

The worse thing I can think about with this transmission is that it won’t fit every Ford truck. Right now, we have a stocked inventory of low mileage used Ford transmissions packaged and ready to go. Most Ford truck owners are aware of the 6l engine issues.

With plenty of trucks with damaged and ruined 6l motors coming in, we end up with more low mileage transmissions than we normally carry. Once we disconnect the transmissions from the engines they are put through a pre testing procedure to insure your success, then we get them boxed up for fast shipping. Find out more about how we can help you out of bad spot fast by calling 866-320-1182 and speaking with a transmission expert. GotTransmissions.com
