Has any one use this in a 4-Speed?
That's what I use
I had a slight gear clash in 1-2 when cold. Went to the factory recommended SAE 140. Had gear clash in all 4 gears. Tried Sta-Lube 85/90 GL4 from Napa and it was better, but still had the cold clash from 1-2. Was advised by a local Mopar guy to try Penzoil Synchromesh before replacing the synchros. It all but eliminated the problem. I'm sold on it.
Thanks for the reply's, I just read some where the it might be to light duty for and older 4-speed. My 69RR is a driver and will never see the 1/4 mile or hard uses
Thanks Tom C.
Hey Tom. If I had a question on what to use would call Brewer's. Here they are the guys to talk too. If you have any doubt's. Not to step on any toe's. Brewer's PH. Number is 937-947-4416.
I’ve had good luck with Lucas 90 wt gear lube in every manual I’ve ever run until I had a Tremec that reqired ATF, and my Passon 5 gear that gets 75w140 synthetic. Not cheap!! Worth it though.
I have a '70 RR w/ a 4 speed 833. Some of the local old Mopar guys swear by GM Vehicle Care Synchromesh, that is currently available at Chevy dealerships. At $15.00/Litre, it is quite pricey. Have others heard of this recommendation?
