An oil analysis leading up to the overhaul showed that the engine oil sheared down quite a bit. So, I did some research and switched to Red Line MTL that is made specifically for manual transmissions and was recommended for this application. Now at 460K miles everything is still quiet and working like new. I learned my lesson.
That's why I avoid multigrades gear oil (like a 75Wxxx) like a plague.
Often times people are 'made to pay' for using multigrades gear/transmission oils (blindly follow manufacturer recommendation with unnecessary VII's) and I don't.
