Automatic transmission ?
I just purchased my first corvette 1999 C5 coupe with an automatic and 75,000 miles on it, I have all the maintenance records on the car but noticed the transmission was never serviced, should this be done now? it seems like it should shift faster through the gears when WOT if so what fluids would you recommend?
thanks any help would be appreciated

If your fluid looks and smells ok, then leave it alone. But if you are going to make a fluid change, make sure you use a quality Dexron III non-synthetic oil. (AC Delco, Mobil, etc.) With the pan dropped, look in the bottom of the pan and see what is going on. The magnet should have some fine powdered metal on it and the bottom of the pan should be clean. In otherwords you should not be able to write your name in the bottom of the pan with your finger, if you can then this is clutch/band material. If the material on the bottom is slight or none and you want to keep the transmission alive for awhile, you could add the TransGo modified Shift kit. This will extend the life of the transmission and quicken the shifts at the same time. The modified version offers smooth (but not firm) quick part throttle shifts, and quicker and firmer WOT shifts. If the material is much more than slight, you are probably looking into a rebuild in the near future. Dana
