I HAVE A GMC 1/2 TON 4WD. I JUST DID A TRANSMISSION SERVICE ON IT AND THE NEXT DAY I LOST REVERSE AND THIRD GEAR. WOULD THIS BE CAUSED BY THE GOVERNORS IN THE TRANSMISSION?

1986 Chevrolet Silverado

The transmission is a TH400 that has been sitting for roughly 10 years. The transmission was taken out of a truck in the hedge row and place into an everyday driver

You should really put the question in the question area. Check for being low n fluid. If it's around two quarts low then it's toast. You might check the filter because ther eis an o-ring around it and if it doesnt' seal good it causesair to get in and do that. And it may be a bad seal or the low reverse clutch is out as well asn teh direct clutch.
