Hey, I have a 2000 F-150 4.2 2WD, I blew out a 2-3 servo awhile back, replaced it, truck ran fine. I have to get in ispected and it failed cause of a P0750 I believe (solenoid A) So I just went in and replaced it, now im throwing a P0755 code (solenoid B) and my truck yet again wont shift out of 2nd. I really hope it isn't the servo again because I don't want to pull the valve body but I heard of people throwing that code and having similar problems, what does solenoid B do? I was also told it could be the plactic electrical peice that snaps on over the solenoids having an issue, or even the wiring harness, any help would be appreciated(:
