  • Question : Convert 4t60e into a 4t65e?

    I have a 2002 aztek i think is a good pave to start. About 30,000mi ago I replaced 4 clutch hub, 4 clutch, and all the solenoids on my valve body because the 4th clutch hub splines went. Well now i think my torque convertor is going bad. It shutters when climbing hills, can't complain I'm at 230,000 mi with an original trans and only the work listed above has been done to it. But if I'm pulling the trans for a convertor, I'm just going to replace the trans, seeing as it's so old.

    So i found a guy at work with a powertrain from a 98 venture with 102,000mi on it. He blew the trans towing with it at 80,000, had it rebuilt, drove it to 102,000, and pulled it when the body rotted to far. So i bought it, now i find out its a 4t60e not a 4t65e. I know they are very similar, the question i have is how similar? The 60 has a 7 pin connector coming out of the side cover along with a vacuum line. The 65 has a 20 pin connector with 14 pins being used.

    Call me crazy but can i just swap the valve body and side cover from my 65 to the 60 and run with it? I have never herd of anyone doing it. Any insight appreciated.

    they're similar, but not similar enough for that. the PCM would need to be dealt with to allow it to operate it correctly.
    1995 Monte Carlo LS 3100, 4T60E...for now, future plans include driving it until the wheels fall off!

      That was my fear. Unfortunately transmissions are not my strong suit so I felt i had to ask. I considered trying to rebuild my trans and stealing the torque convertor from the venture powertrain but i hate to do something wrong and have to pull it again.
      I guess i will just sell the powertrain i have on craigslist. Anyone in SE Michigan interested in a dressed 3.4 and rebuilt 4t60e?

        No it wont work. You would have to down grade your harness and pcm to a older year and older axles with the different spline count.

        96 Z34 3.4 SC DOHC Getrag, 284 5sd manual transmission, stage 3spec clutch, 97 engine, 97 pcm, S3 intercooler 1 of 1 Roots SC LQ1 in the world 8.5 psi.
