i got problem had to replace the tranny 3 times and never solve the problem about when i smashed the throttle it hesitates and stalls like goes to nuetral and revs until i let it go it stops. the transmission machanic says nothing wrong with the tranny. he says is a sensor,already put computer to check ses light it says Knock sensor and map sensor ,Maf sensor and tps sensor but already replace the maf and tps sensor . Do you think it maybe a knock or map that messes up my tranny or tranny slips

Couldn't hurt to try. Knock sensor isn't an easy fix(gotta bust off the intake manifold to get to it) but it's a hell of a lot cheaper than replacing a tranny.
