Re: Help! Trans Problem

If ya need a tranny rebuilder, I have one in the Austin area. He rebuilds tire killing trannys.

Check for a loose line or broken line. Check the fluid. Is it burnt? Smell bad? Does it look nice and red?

Oh yeah.. it could be a broken cooler line.. I had a pinhole in one of mine on my 77 Scottsdale.. I probably lost 4 quarts of fluid in 20 miles..

Re: Help! Trans Problem

i just helped replace a tranny in a burban a couple of weeks ago.. now its back with a bad tranny.. on the left rear side, on the back of it that round thing that has the metal flip thing holding it on, forget the nameof it. it has been pushed out enough that you can see the rubber oring behind it, and where it would normaly be seated at... look at that while you are under it...

You mean the governor cover?

Check the rear seal as well. If the trans is jumping out of gear, dropping to the next gear, or doing weird things like that, its due to a lack of fluid at the clutches. Low fluid level, due to a leak or foaming from over filling, or a clogged filter preventing fluid from being pulled from the pan are typical reasons for dry clutches.

Actually check everywhere something bolts to, sticks in, or protrudes out of the case for leaks.
