[Tigers] Toploader trans fluid

Actually, Tony said 'synthetic transmission fluid' ... which would be ATF?
The 'world class' T5's use the ATF because of the needle bearings... the
older T5's use gear oil.

The Ford 5 speed requires ATF.   If you put 80w gear lube in a 5 speed don't
expect it to shift easily or at all if it is cold.

It just seemed a bit unclear in your statements.

When I replaced the axle bearings I changed the rear end lube out (80W90).
Thinking it couldnt hurt to add new gear lube and drain the old. But now Im
thinking of changing it again and going to a synthetic gear lube. I dont
believe there will be any problems with it.  Dale A. also says to use
sythentic transmission fluid on the Ford 5 speed. I dont believe sythentic
gear lube normally used(gear lube)in the stock transmisson would create any
problems with the brass syncronizers or any other metals. Just my opinion.
