Carlos,
I'm no tranny mechanic but I've torn apart and rebuilt a few of them in my time. As long as the fluid is coming out without chuunks of obvious pieces then I would believe that it is just the normal wear of the clutch steels and the friction plates. You don't mention how many miles you have on your Vette but I would guess over 100K. For the most part I would consider this normal. As far as three changes in two weeks ... I don't think this is going to help. Once the frictions are worn and start rubbing the steels it is just a matter of time. I would stop driving it until I could get the tranny rebuilt. A rebuild should only cost around $850 or so for the rebuild kit and labor, this is not including any "hard parts" that may need replacing. And again this would be if the tranny was out and you took it to somebody. The Vete setup is a real PITA to get the tranny in and out, plus adjusted just right, so that may be a large part of the cost you were quoted. If you have the ability, time, facility, and "PATIENCE" I would take the tranny out myself. You will probabally save yourself around a grand or so. Plus you get more familiar with the underside of your Vette.
If you are going to go direct I can suggest a place. These guys have been around for a while and they are very knowlegeable about the 700R4, and they build some stout trannies, they only use parts that have proven themselves. Some of their trannies will tow around 6,000 lbs in OD ... this isn't supposed to be done in a 700R4. You can look them up at
www.transmissioncenter.net I think they are running a special on trannies now with "free shipping" ... I just had to order some stuff from them (no free shipping on my parts
). If you get a tranny from them you will most likely have to replace the tailshaft housing with your original one ... due to the Vette's support beam ... and most likely the speedo gear from your output shaft, theirs may not come with one.
Good luck and hope this helps a bit.
