I got my car running last night and I had it in the park position but the wheels kept spinning. I have one of those fancy b&m ratchet shifters. The car was on jack stands so i put the brakes on and it really didn't slow the engine, i then put it into drive and put the brakes on, it did slow the engine. I really dont know whats going on. My dad said there being some park part in the trany that could be bad but? It is an fmx by the way.
