[Healeys] Transmission Oil

[PG]

Ok..for those of us who have been on this list for more than a couple of
years, we all know that trany oil has been beaten to death...

 

However, here's an observation..I recently switched from 30wt non-detergent
oil to Redline MTL and what I found surprised me...

 

I found that my gearbox ground going into both second and third both in
upshifting and downshifting.it's like the syncros can't grip.  Keep in mind
that I rebuilt the transmission last year.

 

I'm wondering if the MTL is too thin an oil for the transmission..  I'm
thinking of switching to MTL 90

 

Thoughts??
