My Cavalier's Getrag 5spd has a small annoyance. It growls loudly at low RPMs because of the relatively rough power delivery of the 4 banger. I believe some Opels have this transmission too and they have similar issues. Otherwise, driveability is wonderful and at 120K, all synchros are good as new.

GM's recommended fix is to add additional fluid. The standard fill is 1.8 quarts of automatic transmission fluid, I've got 6 in there to quiet it down. There haven't been any ill effects after 30,000 miles. Shifting effort increased a bit, probably due to the fact that the synchros are submerged, but that's it. Would you guys expect substantial gains from going back to 1.8 quarts?
