after a friend put in a stillen valve body i am getting little power when i push the gas pedal complete down. 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.

i have a 05 35th anny auto

 

Take it back to who did the install . If you did it...ummm...call stillen

 

we called stillen and they said never heard of the problem n we will call bak later. could it be the ecu need to be reseted????

 

it was be installed incorrectly

 

are u sure. and how would it be install incorrectly, it can only go in one way and the car shifts fine

 

I would say...if it was installed right . Check the fluid . And I hope you filtered the used fluid before putting it back in

 

the fluid is very pink and cleaned, i put in wat i took out, problay lost a some oil. could it cause the lost of power tho

 

check this thread Seems he is having a similar issue

 

If the torquing of the bolts is done improperly, fluid will leak out where the valve body seals against the trans housing.

 

ty for helpin me, ur the only one.

 

thats some funny stuff, hahah

 

do u hav a intake? it mite be loose?

 

I have the SAME PROBLEM except my car is a 6MT the dealer just replaced my tranny under warranty a few days ago then my car started doing this but its intermentitnt, sometimes it does work normally but it usually just is like 50% throttle wierd!!

 

No need for two of these. Let's continue it in his other thread...
