Transmission 4T65-E Question
I am trying to swap a BROKEN 1999 SLE transmission for 2003-2005 GM Buick Pontiac 4T65-E. Will the newer one work on mine even though they are different years?
I know that things have been improved on it, but will it be comptatible with my ECU? My RPO code is M15

I DO believe that it should fit but I would like other opinions thanks alot!!

GM never had a 2.92 Ratio
What is the gear ratio for the trans you are going to use??

FINAL drive ratio. You HAVE to know what yours and the new one are.
Your choices are:
3.33
2.97
2.93
2.84
3.05
3.06
Not all of these are possible, but they are the common ones here. I'm making you do your homework for a reason. I know what you probably have in the car, but I have NO WAY of knowing what the ratio of the trans you're looking at is. YOU have to find that.

So you are showing me what? That you have an M15..... All of these transmissions have a 2.92 to 1, 1st gear.... Thats not the Transaxles overall ratio...
You need to know the overall ratio of the transaxle that you intend to use on your car... as well what is the ratio in your car?
