[Healeys] Transmission Oil

[Bob Spidell]

My BJ8 gearbox shifted smoother when I switched to MT90 from 20W-50.  I wasn't expecting any change in shifting--I was 
hoping the O/D would activate a little quicker--so there's at least a little objectivity to my observation.  Oh yeah, 
the O/D does activate a bit quicker, esp. when hot.

Lots of people have made the switch from engine oil to MTL or MT90, and the only complaint I've heard is the gearbox/OD 
leaks more.   MTL and MT90 are both formulated for manual gearboxes; seems like something else is at play here.
