    While pulling hydroboost parts yesterday, we found a 1993-ish diesel (4x4) with an auto. The drivetrain was long gone, but we looked to see if we could find the 4L80E stand alone computer. I have no idea what one would look like, but we did find a small plastic computer behind the glove box. It had 2 or 3 wire connectors on it. It was the only box that I could not identify on the truck - plenty of other relays, cruise control boxes, etc.

    Does anyone have a pic of said box, so I can compare the one we got?

    6.5 diesel is an L65 RPO, the 4L80E is RPO MT1.

    I see a few different part numbers listed for various years, you'd need the number off of it to try and compare. Usually the paper label is still there...

    Not sure if this one is the same as the stock one in appearance or not but this is the GM controller for swapping in the 4l80E

    It does have the paper label still. I'll have to see what comes up. Also, it looks pretty close to the pictured one.
