Tranny Help!!

FWIIW, prob the most important difference between the automatic transmission on a 2000 V6 and a 2000 GT is the bolt pattern of the bell housing.

A 4R70W from a V6 will NOT bolt up to a modular V8! Count the number of bolts on the starter. A modular transmission has 3. The others have 2.

They may have the same designation but they are not the same.

For any automatic with shifting problems, the first thing anybody is going to ask about is the condition and level of the fluid.

Take a look at the 4R70W case. Do you see a seam between the bell housing and the body of the transmission?

If the swap could easily be accomplished by a bell housing swap, I would have mentioned it. The case is all one casting.

If asking for an opinion, rebuild the unit you have. A salvage unit is a crap shoot that may not be any better than what you have. Besides, if you rebuild what you have you don't have to worry about speed sensors or wheither or not it will fit.

Sometimes 2140+ posts entiles one to a little tude...

Besides, this is the tech section. Some of what should be going on here is to teach ppl how to fix their own cars. Before teaching can start, some engagement of the student's brain has to occur. In a perverse sort of way, I'm trying to get you the think through the questions before asking.

I'm not one of those ppl that believes there are no stupid questions. There are stupid questions when the questions are asked without forethought. So maybe I hit you just a little too hard.

But look at the quality of the response! Accurate. Timely. Great value for the $$ spent wouldn't you agree?

The forums are filled with tons of post where ppl are assuming that because it's called an 4R70W, that any MY can be swapped with anyother MY. It's just not true across the board. Some swaps are easier than others.

But, within the same MY, the internals of the 4R70W are almost exactly the same. The differences are usually very minor. Since the 4R70W is an electronically controlled transmission, the PCM programming actually has more to do with the "feel" of the transmission.

I encourage everyone to do their homework. The Forums can not take the place of a professionally written manual. Nor should everything read be taken in 100%. Use your brain. Do the home work. The end result will be a greater chance of sucess.
