Yes, just equates back to pressure on the gear face. And what Art mentioned how the gears are cut can affect both how much the gears must actually slide against each other and the actual amount of contact area they have. As for a 1400 hp FWD car using ATF could it be due to necessity as the transmission and differential share the same oil?
