I have a friend that has a 91 Integra GS automatic and he is having transmission problems. It does not want to shift gears when it gets worm but if he shuts the car off and on it will be fine for a bit and than again. He was told that one solenoid was damaged. Does anybody know which solenoid it might be because I heard that there are two in the transmission. Also is it possible to change the solenoid or will he need a new trany. Any help will be greatly appriciated.

 

Any help will be good
