Ford 4R100 Transmission For Sale
I can’t think of a more structurally sound extra large heavy duty automatic transmission than the Ford 4R100. Often I have spoken of how heavy duty the two other American car companies largest transmissions are, yet this one has several tiny flaws in the valve body and cooling arrangements that force plenty of units go bad before their time is due.
The 4R100 proceeds the E4OD. Which stands for Electronic 4(speed) Over-Drive. It is fully computerized with a beautiful high technology control system that provides excellent shift quality and super pulling power for the large loads.
I want to address the small shortcomings built into this transmission from the factory. I have seen and had to rebuild more 4R100 and E4OD transmission due to these relatively minor shortcomings.
1. The most common failure of this transmission is due to insufficient automatic transmission fluid (ATF) cooling. It is not entirely the transmissions problem, but an indirect problem that can be cured before you have a serious transmission failure. It is also advisable to take these actions if you buy a rebuilt or used transmission from us.
Simply put, especially in trucks that work hard, the transmission fluid does not cool down enough through the stock cooling system, therefore burning the transmission fluid and causing a terrible leak out of the front of the transmission and or literally burning the clutches, bands and any plastic parts along the way.
Using a non synthetic transmission fluid falls under the overheating category. Synthetic ATF can take twice as much heat before it breaks down.
My advise is to add an external auxiliary transmission cooler in addition to the factory system to effectively cure the overheating problem.
2. The second issue is a tad bit more involved and is usually done at the time of a full rebuild. Although the smart owner will have this service performed immediately upon receiving a vehicle with said transmission.
What we call this procedure is installing an upgrade kit. The kits addresses many issues and upon rebuilt turns this into more than the beast it was intended to be. However, part of the kit can be installed without any invasive treatment. And it is not a bad idea if you buy a used transmission to have a professional perform the installation of the components that can be installed while the transmission is still in the vehicle.
I want to make this abundantly clear. If you have a bad or malfunctioning transmission, don’t do anything until it is checked by a profession transmission mechanic.
The point I want to get across is that we sell rebuilt 4R100 transmissions. Every rebuilt unit gets an update kit. The entire kit is installed while being rebuilt. The cost of the kit and extra time to do the procedure is like making money. You will now have a transmission you can forget about except for regular maintenance with synthetic transmission fluid.
Most of our customers don’t believe it is the same transmission after their their first road test. We recommend an auxiliary cooler too, of course. If you choose to buy a quality used transmission from us, at the least, we recommend an auxiliary cooler, the upgrade kit is worthy, but not necessary on a used transmission.
