So ok i have a 1996 Oldsmobile cutlass supreme with a t460e transmission im getting a 2001 gtp 3.8 sc II but tranny slips my question is is the transmission from the cutlass bolt on to it if so what needs to be done and what do i need or am i better off scrapping the cutlass since its motor is complete junk now and buy the needed transmission for the gtp anyone who can give me a correct answer that would be awesome

the sc ones have a hd trans, scrap the other and have yours rebuilt, im not for used trans your likely just going to have the same issues and you will be out what ever you paid when you have to have it rebuilt anyway

Physically, the transmission will bolt in. But, electrically, software wise, they are different. And Justin is correct, the 4T60-E is non HD vs the HD version in the 2001 GTP.

You are better off scrapping the 96 to get a new trans for the 2001. The bad thing about the 96 is, HP Tuners won't touch that year. They only support 1997 and up. (should you decide to tune it)

well thanks for the advice ill just start looking around for a used one with low miles do it that way insted of going through the eletronic bs hassle

question i guess is though if i really wanted to put the transmission on there would it work and shift fine? etc im assuming it wouldnt handle the power of the vehicle im picking up an 01 gtp with a 3.4 pulley and mods that are done so it can run the 3.4 pulley

Even with a stock L67 3800, the 4T60-E'* are not able to handle the torque put out by them UNLESS you baby them.

But if its a year mismatch, the computer won't be able to control it like it should. They changed the electrical connector and the shift solenoids over the years.

if you are going to modify it you definitely want to have it rebuilt not buy a used one
