1992 Chevrolet Corvette

Dear Doctor: I am the original owner of a 1992 Chevrolet Corvette with 65,000 miles and a six-speed manual transmission. The car runs and shifts perfectly. I have never changed the transmission fluid and have been advised that at this age changing it could potentially create problems. What do our recommend? Adam
Dear Adam: You would not do any harm or cause any problems with a transmission fluid change. I would also suggest changing all the fluids, including rear differential and adding the GM posi-fluid additive. This will prevent chatter during tight cornering at slow speeds and prolong rear end life. You should also change power steering and brake fluid. This can be done with a turkey baste to draw out the fluids. Note: do not use the same baste for the brake fluid or power steering fluid. This would contaminate either fluid, resulting in expensive repair work. When changing the coolant, use the Dexcool, if available or good multi-use antifreeze.
