Sound,s like the ECM may be going bad if random cut off.

On that thought...with the 99 engine in the 2000 truck/ ECM..I lost overdrive ...but by putting the 99 ECM Into the 2000 truck I got overdrive back ...but now the no bus an shutting off issues... almost have to be a difference in ECMs

Bingo! you got it.. PCM and instrument eeprom don't like each other and aren't communicating not to mention the PCM is different from '99 to 2000

I can putt the 2000 ECM back in and see what happens...but what about the loss of overdrive... surely the transmissions are compatible?

Ok did the ECM switch back ..now I'm back to only having a 99 engine and transmission in a 2000 truck...the no bus indicator is gone and truck runs great....but I lost overdrive?????
