after a friend put in a stillen valve body i am getting little power when i push the gas pedal complete down , it seems like i it only pressing the gas pedal 3/4 of an inch. the rpm just rises slowly very slowly. i was told that everthing was put in right. when he was putting in the transmission fluid some of it spilled out, could that be the problem. i also reuse the same fluids. should i reset the ecu

i have a 05 35th anny auto with 850 miles

 

man, this is your third post on three different sections on the same problem. This is likely a problem no one can answer with out the ability to inspect the car. try reinstalling the body or take it to a tranny shop. Plus 850 miles is to soon to be upgrading tranny parts the car hasnt even been broken in yet. You and your friend messed up.
Sorry I cant be of any help.
