1999 Mercury Mountaineer Base 8 Cyl 5.00L

Transmissions & Drivetrains

No up shift to 3rd on a 4r70w transmission

I pulled on the battery cable a bit to cut a piece of to put a new terminal end on. Then the transmission wouldn't shift into 3rd or overdrive. Just revs out like it's not getting a signal to the selinoid to shift . I have replaced the selinoid in hopes that it may have just went bad . No such luck. I believe it's a wiring issue. It worked fine before the tug on the positive cable .

I would like to know the same thing. I was driving my today and it wouldn't shift into 3rd or any other gear. It would go from first to second with no problems. Then trying to go to 3rd it would do nothing but rev like it was in neutral until I slowed down then it would engage back to 2nd gear.
