I also had a PCM in my reg cab constantly throw codes, flash the O/D Off light and shift poorly if at all. I finaly figured out it was the PCM when I swapped with a different truck, that PCM is now in a 5-speed truck.....

Not true. My '97 used to do this to me, something with the speedo in the dash. always happened when I left work and drove slow for 5-6 blocks, all of a sudden it would just stop going forward, you could rev and rev and go nowhere. slam your hand on the dash and bang, away we would go, a bad ICP conection will cause poor shifts, as will a bad Rear ABS signal.

Well I was moving when it went bad whatever it was no grinding noise no metal noise was climbing a hill and the rpm's shot up and I started rolling backward. Like I said it was like I dropped a driveshaft. Weird

My buddy had the forward planet split in his old idi e4od...pulled up to a stop sign.when he tried to go...just NOTHING! Never made a noise or anything.not that, that is your problem but it can happen.
Have you tried 4wd? Could eliminate the transfer case out put back as problem.

Not to throw something odd out there, but when my TC (transfer case) went in my old truck, it did this same thing. I managed to get it into low range and it moved then.
Just a thought if the chain broke in the transfer case.

You got an auto, mine was stick. I put mine in 4 low and rocked the truck and it popped into 4low.
It took so effing long to drive it at 10-15 mph to the trans shop.
Twas just a thought though ya know?
Trans issues are a nightmare no matter what they are.
Your trans might be fine an the chain in the Transfer Case might be snapped in half giving you the alure of a broken trans.
I'm not sure if you can check that by looking though the drain port on the Transfer Case though.
I'm not sure if a TRS fail will cause a miss shift issue.

Yeah I appreciate ya thinking and trying to help I was just answering the question. It is a automatic. Main reason I was gonna not try to throw much at it is bc I want a manual so sell it and buy a beater with a stick in it
