Hi everyone,
I'm swapping out the 4L60E for the 80E and see that after searching threads, they cover the newer 80 pin PCM. Can someone tell me what pins I need to use for the extra speed sensor. Already re-pinned the main connector on the tranny.
Also, the 80E I have has a bolted yoke instead of a slip yoke. Will I need to find a slip yoke for a TH400/4L80E?

Many thanks!
Matt

Matt sorry I can't help you with the computer part but I'm sure its in the stickies or some where posted here if you search. I would have to think that gm did make a vehicle with an 80 using the same computer that is in your truck. Not sure if these can be re-flashed but that is what I would look into. Because of the style trans you have, when you go to order a yoke make sure to get one that is an o'ring style. By this I mean one that the end is machined smooth for the o'ring on the output shaft to seal. If you pull the old yoke out of the 80 you already have you will see what I'm talking about here.
