mine has just std 90 wt gear oil.Tom

same as above in mine

LOL Short story, I had a manager move from South Florida to Memphis TN back in 1987. He had a Ford Torino with a top-loader 4-speed; for some reason it wouldn't shift after the move?! Well, that's because he had it filled with straight STP which apparently worked in South Florida but not so well in Memphis during the winter! LOL It took FOREVER to get that STP to drain out of the tranny it was very thick. JD

That is funny.....
Thanks for getting back to me with the info on the lube tom s and performerrpm....Chris

Manual lube
 

I allways used 90w gear oil in my 70' Muncie 4sp, but I was with my brother-in-law when he bought a super T-10 for his camaro and the guy he bought it from told him to use ATF for smoother and faster shifts. That is what was in the tranny when he bought it. We were going to try it, but he sold the car before we got a chance.

We have used Redline MTL 90 manual transmission oil in the racecar's ST10 for 15 years.

In real life, you can run about anything that will keep the bearings wet, temperature willing, with varying degrees of synchromesh response. Some additives are too slippery and the gears will grind. Some are too grippy and the gears will grind. Some are just right.

Yep 90 weight is it.
