Manual transmission fluid level

General Discussion

Last year, my rear wheels locked up because my rear output bearing wasn’t getting enough fluid.

I bought another transmission from a junk yard.
Both transmissions are identical. They are both from an 89 4x4 manual justy.
The dipstick in the transmission I just bought is about an inch shorter than my old one, so it takes almost an extra quart to hit the full mark.

How can I determine the proper fluid level?
There is a breather tube at the top of the transmission, so if it’s over filled will it just spit out the extra fluid?

I’d use the one that came with the engine. It’s possible that the shorter dipstick reflects design changes, and even possible that it was implemented to stop problems with output bearings not getting enough fluid. :grin:
