It has more friction.? This fluid has been recommended by many people whith modern cars that have developed shifting problems.? I have a case of the stuff for my Honda S2000.? I'm going to try it in the Healey.

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,?
