Tranny problem - DFW area repair shop???

[Andrey]

Have you ever did exchange of tranny fluid ? not just drain and fill but full exchange. What is your driving habbit - do you shift "manually" while driving ?

That noise might not even be the transmission. Perhaps you could look for a reputable four wheel drive shop rather than a transmission specialist.

Althought I've never used one myself, I've only ever heard bad things about transmission shops in general. It could be a bad rap. I tend to believe that any business that specialized is up to something. Sure transmissions fail, but any competent mechanic can replace a transmission. Heck, if you're careful, a reasonably inclined mortal can rebuild them. I had pretty good luck rebuilding a 700r4 a couple years ago and that's the first one I tore into - drove it like a madman and even pulled stumps with the truck and it's still the strongest feeling unit I've driven. The main trick is having good snap ring tools and a clean operating area.

Oh yeah, and always put red loctite on transmission front seals Nothing like having your truck bleed all over the highway 50 miles from home. (early 700r4's had a too-small fluid return hole at the front seal)
