I have a Ford Ranger 1996 4.0L OHV 4WD

Question:  I have a M5R1 5 speed that was making noise and a little hard to shift but worked ok. I pulled it and replaced bearings, seals, and synchronizers. The 5th and reverse slider teeth were worn on the tips so I replaced that slider. It works shifts and sounds good. But it now will jump out of 5th gear. I was sure I put that slider in correctly, the dot to the rear of trans, but wandering what else it could be? Would appreciate some advise.

Answer: From your description of the problem we suspect that the 5th gear engagement teeth are worn... you will need the following part:

• MWTF1TZ-7158B-R 5th gear (counter shaft) your cost is $72.80 plus S&H.
