    How do I make a 4L60E work in a 98 suburban with a 6.2 diesel?

    You'll need a standalone controller for the electronic transmission - something like this: https://www.painlessperformance.com/wc/66501

    There are other options out there, just that was the first one I turned up.

    Wouldn't a 1998 have a 6.5L and either a 4l80E or 4l60E? Seeing as a 98 would be 'fly by wire', I would say have the ECM flashed or reprogrammed.

    This is an old thread...
    I would assume he was looking at putting it in one that had a gas engine in it

    The 6.5 was never married up to the 4l60E....4L80E was the box used.

    The early 6.2 (1500 trucks) got the 700R4 (4L60) and that was a ticking time bomb.....I tore up several 700R4 behind 6.2's
