Hi Bill,
Not to my knowledge. "Friction Modified" can mean two different things.
IE more friction or less friction. The Healey transmission synchronizer
rings can benefit from an oil that has more friction (less slippery) so
that the synchros can grab harder & quicker when you shift. It also
makes OD engagement more positive. Redline MTL & MT-90 have higher
friction coefficients than some other lubes. On the other hand, motor
oils usually work better with a lower friction coefficient, except
during ring break in.
Some more modern transmissions seem to benefit from a lube that has less
friction, lower friction coefficient. I'm really not sure if the GM
"Friction Modified" has a higher or lower friction coefficient than
standard. If it means less friction, it would be worse in the Healey
transmissions.
I do know that on automatic transmission fluids, "Friction Modified"
means that the lube has less friction to promote smoother shifts.
Regards,
Dave Russell
