it was slipping for a while, but now it just doesn't engage at all. i have an A4 Z28. i'm clueless. i have enough fluid and the motor was rebuilt a few thousand miles ago

 

you burnt the band up

 

Does 4th work?

 

yes, fourth works. i'm getting the Solenoid "a" code

 

*bump*

 

well there my friend is your problem

 

change the sylanoid then

 

but that doesn't make sense. first gear engages when both solenoids are on. second is only solenoid B, third has both off, and fourth has solenoid A on. it looks something like this

# A B
1 on on
2 off on
3 off off
4 on off

if solenoid A does not work properly, i shouldn't be engaging 4th either....please correct me if i am wrong. i don't know too much about auto transmissions
