completely washed the engine compartment yesterday, drove the truck to town. smoked some people out, trans worked fine! noticed that if you mashed the pedal from a stopped position it didn't want to shift out of second, had to let off 1/4 pedal. i stopped shifted it manually samething no change, continued home would not shift into OD! i think the comverters locking up cause it will drop the rpms and will increase when you tap the brake (200-300 rpms). by washing the engine compartment, could of caused this or what? it acts like it coasts when you let up on the pedal (55mph give or take a little.)

it had a manual switch at one time. it got repaced by a new harness so its back to the computer lockup now.


any ideas
