p71 trans problems

[g047]

ok guys I need your help im working on a 2001 CVPI for a friend hes about to loose 1st gear , when we went around to trans shops to see about a rebuild we got 1800-2000 dollars a few times so taking her to the shop is out of the question ,,, so my question is if we grab a trans out of a 96 with the w in the vin will it bolt in and go or is that too old of a trans ???

The AODE-4r70w is one expensive bitch to rebuild..The one out of a '98+ should work ok without any issue.

No. It's too old. While the basic tranny is the same, the wiring and solenoid block setup is a wee bit different.

I find it a bit odd that he is about to lose 1st gear, usually, it's overdrive and drive that goes out in these cars. Methinks you need to run a proper scan of the ECM, and get some live data from the tranny to see if there is actually something broken in there. Occasionally, it's something simple, such as a MLPS, or solenoid block in the valve body that's the problem.
