I start my car and it has not warmed up yet I push down the gas pedal I move then it seems the car instead of upshifting it will shift to neutral by itself. I have an autotragicmagic. then the car will sit there revving yet going nowhere. I have to turn off my car then restart to get rid of problem. Now if I let it warm up it does not do that. What could be the cause? Low tranny oil/ bad tranny oil/ bad tranny/ ecu shifting incorrectly/ some sensor malfunction/ electrical??? Please let me know any info. I had my tranny replaced 1 yr ago with a shift kit and transmission cooler.

Guess I'll start it off with the basics.

Throttle body clean?
IACV cleaned?

check the throttle cables under the hood, make sure there not loose.

 

done that, it has to be something w the transmission
