Ok so what could be my problem ??? Here's the situation : If the gear selector is in D or 3 nothing happens, but if I put the selector in 2 or 1 then I have manual 2nd or 1st. This is in a '99 GMC Sierra w/ a Transgo that was already installed before the rebuild and everything worked fine. New shift solenoids were installed, could this be my problem or the shift switch on the side of the tranny ??? Seems like something electrical to me...Zed
