Will a 4L80E transmission from a 95 Chevy, 6.5 diesel pickup match up to a 350 gas engine?

The 6.5 is locked and is not that good to start with. A 350 would be cheaper all around. I can handle the fuel switch from diesel to gas with a new fuel pump etc.

    The trans is computer controlled (shift points, firmness, ect). You would either need to run a TBI motor from a ’92-95 3-4 or 1-ton truck and get the computer to go with it. Then the new gas computer can run the trans. You will also need to swap the torque converter to a gas unit instead of the diesel.

    OR

    get whatever motor you want, and then use a stand-alone controller for the trans. They cost about $600+ for the controller. Still need to do the torque converter.

    You could run the diesel TC but it just wouldn’t perform to full potential.

    It will bolt up, but a diesel transmission is different from a gas transmission. Diesels shift way earlier and only go to 3500 rpm max. If yo u do the engine swap, you will need a new valve body in the transmission.
    I have a 700R4 in a 1935 Ford truck. It never shifted right unless I drove it manually. It always bogged down. I took the transmission to 5 different shops and no one could figure it out. After 6 years, I was telling a buddy about it and he had me bring it to his shop. He changed the valve body (was a diesel trans and I didn’t know when I bought it at an auto swap) to a corvette valve body and now the truck runs great.
