A-833 Lube help

Using 90W, you might experience hard shifting in cold weather until it warms up a little. I run 50W motor oil in the Borg Warner T-18 4 speed in my 75 F250.......like the book says. Mine is hard to make that first 1-2 shift in cold weather. I haven't tried ATF, although I am sure it would work well.

I have heard good things about the Pennzoil Synchro-mesh stuff. We sell it at work and people say it's very good. Probably the best of both worlds, so to speak.

Modern lubricants have really come a very long way. I am sure you'll have no trouble finding something that will work well.
