ATF Replacement for Older Corvettes
Hi. I am the owner of a 1994 lt1 6-speed Corvette. I'm also a member of a very large Corvette forum. We in the C4 (84-96) Corvette community have a rather large issue involving the fluid in our 6-speed manual transmissions. A few years ago GM discontinued the recommended replacement transmission fluid (GM p/n 1052931) and replaced it with a far less superior multi-use type. Now us 100,000+ '89-96 Corvette owners are stuck with finding a quality replacement fluid. We have been forced to use a fluid offered by BMW with questionable results. Neither GM nor the transmission manufacturer has any helpful info. Since the original GM fluid (GM p/n 1052931) was basically 5W-30 motor oil with additives to help with the brass parts and since Mobil 1 is the stock Corvette motor oil, we in the Corvette community are wanting to know if Mobil 1 has a solution to our problem? Or if we could use the full synthetic Mobil 1 5W-30 motor oils? Thanks for your time.
