I think the transmission is a 9 speed automatic, based on a ZF design . There won't be too many racers that will be running that transmission , most will run a 727 or a 904 . Just like the engine will be running on an aftermarket controller , all these features that the production car have, are integrated into the factory ecm . With all these factory systems removed , it would be so illegal to have a 727 with a brake , or some sort of traction control ,and claim its stock , that if found , would for sure win you some time off . If the car was totally stock , it would be hard for NHRA to make it illegal , kind of like if you used a rental car . Most probably have traction control , but nobody has gotten bounced for it . Using aftermarket or not original parts , you would have a problem , saying its just stock . A little rambling , but you get the point . If the car has a feature that is stock , how would you prove it is disabled , best to have it totally removed .
