My 1999 chevrolet 1500 4x4 wont get into overdrive when driving down the road and the reverse wont engage at all.it has apprx. 130000 miles on it and has been very well maintained.any suggestions other than to put a new tranny.
Not true it is a solenoid problem and most likely an easy fix. Po766 is the code correct?
Sounds like a 700r4 tranny thats usually what happens when they decide to quit you loose overdrive and reverse. About 900 to 1000$ to rebuild.

I had tranny checked out by a tranny guy. He went through and checked the bands. Worked fine when we put it back in. Now after 15 miles its doing it again. Oil doesn't smell burnt but is black. Could it be the bands or something else. Started doing it when we backed it out of the garage but we took off the battery cable and it reset itself. We are stumped too. Spent 400 on engine and 150 on tranny check. What else could it be???
changed my overdrive housing added fluid, reverse shifts but won't engage
