Oil ??

I have a Borg Warner T-10 that I just installed in my Hemi Ford truck. Was wondering if anyone knows for sure what oil to use. Seems like these old 4 speeds used 90w gear lube, but I'm just not sure. Anyone know??

in my 0ld GMs i used 90w

Yep, the new stuff reads 80-90, but it is what I use in the transmission in my 27.

Thanks Pat and Don I thought that was correct but just wasn't too sure. Figured you guys would come to my rescue. Thanks again

try to find GL-4 gearlube as gl-5 is corrosive towards the brass. i remember reading 3 or 4 forums on this subject on muncies and BW t-10's

Are they still scraping oil up of the beaches,you may be able to get some really cheap with free additives to lube your gearingbox so that it has that gear drive sound to it. Just imagine you could start a new trend, gear drive whine from the motor, a nice whine from your gearbox followed by the whine from your quickchange, just wear earmuffs for those longer trips.:LOL:
