Engineering changes on automatic transmission

[Pit Bull]

Does anyone know what the changes have been from year to year on the automatic transmission? I am sure as failures have occured that Dodge engineers have made upgrades and modifications. Maybe I should say I hope they have made improvements

UNH-HUHhhhh... .



And just KEEP ON "hoping", and DREAMING...



MEANWHILE, spend a little time scouting for a good local transmission repair shop!

Myths...

Concerning the auto transmission in your truck abound. It is a damn fine transmission when used and maintained properly. It is designed for the stock torque and horsepower which your truck was supplied with. It will give you long and faithfull service if it is not subjected to mis-use and poor maintenance. If you are pulling loads at the high end of your truck's rated weight, down shift out of OD on hills, and change the fluid every 12000 miles. If you decide to bump up the power, and pull very heavy loads, invest in a DTT torque convertor and valve body.

If you intend to use it only as transportation, and pull normal loads, it will most likely give you long and trouble free service.

Forget the doomsayers that abound on this site, have a ball!

There have been changes made and they were driven by problems. My original trans lasted a whopping 128,000 miles. It died when towing a light trailer at 70 mph. The '94 and (I think) some '95 models didn't have a now present lube port in the main shaft og the trans. The instructions in the shift kit I got gave instructions on wherre and how big to add it.



I replaced my trans instead of rebuilding it with a new unit from Dodge in January of '98. It had the larger pan and external pressure tube on the valvebody like the newer transmissions have.



DC has also been playing with how the shifts are controled. On the '94-95 models, there is one less solenoid on the valvebody. In '96 (I think) if you enable your O/D, it doesn't drop the TC lockup before upshifting.



In '95 or so they moved the trans temp sensor into the trans instead of leaving it in the line.



The newer transmissions have a much better record than the old ones. The changes seem to have paid off but you will still have failures, just less of them.

I had a new FE clutch installed yesterday and in talking to the mech learned the new autos will be and inlarged 45RFE transmission. The 47RFE will be electronicly shifted. The 45's are in the Durangos and are unreal. the one I drove was fantistic. Also he said the 3500s would be 8 ins. longer than the 1500s and the bodys would not be interchangeable as they are now. The rear door would be a larger one than the 1500 now, with the 4 door, of course. .



Thats what I was told.
