ok took it to a trans shop. guy said its fine. so tranny is out of the question. since driving it it will run perfectly fine at slow speeds and at slow acceleration but if you try to accelerate fast or put a load on the engine it acts like its missfiring BUT IS NOT!
replaced
tps
maf
fuel filter
coil pack
plugs
wires
converter is cut off so no blockage.

Revs fine in park just when it has a load on the engine
ANY IDEAS??? maybe a fuel injector
