No, it is the gears too. Go over to the forums at fastcougar.com and talk to Leo Capaldi who is currently driving a Cougar in the Speedvision World Challenge. He has stripped the teeth right off the gears. Granted he probably puts more wear on his transmission in one race than many people on the street put on theirs in an entire year. (Porsche uses a generalization that 1 mile of racing is equivalent to 1000 miles of driving on the street.) But with turbo/supercharged 3L SVT's coming soon probably putting out a fair amount more than the 300hp Leo puts out, I think we'll start to see some new types of failures in transmissions.
