Hello all. Sorry to bother you, but can anyone tell me which pressure switch operates first gear? I've found all sorts of pdf files and parts listing diagrams, all I can decipher is there is a 3rd clutch press. sw., and a 4th... There are two listed as shift solenoid "A" and "B". Is either one of these it? So far, no problems with 3rd or 4th. Thanks in advance, Mikie.

 

hey mike im eddie from aamco transmissions their is no 1st or 2nd clutch pressure switch only 3rd and 4th and a mainshaft and output speed sensor then you have your Duel pressure solenoid on top then u have the 2 single shift solenoids in front of the dual preassure let me know if you need any more info or pics i just bought a 99 yesterday and im going to get ready to rebuild it this weekend.
