I am suffering the notorious 3rd gear issue in the 6-speed manual transmission. Car is in good shape, engine excellent, always garaged, body great. 176K miles. Looking for a source for a good re-manufactured transmission. Any references anybody can offer out there?

No need to remanufacture your transmission, simply replace the MTF with 2.3 quarts of ACDelco Synchromesh Friction Modified (that last bit is very important, the non-Friction Modified stuff sucks); this MTF should literally cure your issues the instant you put it in.

 

Thank you. I installed the Friction Modified AC Delco Synchromesh fluid. No improvement. I suspect the gear set is too far gone. Any other ideas? If not, got a source for a rebuilt/remanufactured replacement transmission?
