FYI: it makes perfect since to have a rev limiter in P and N. the first vehicle i ever owned was '76 ford LTD when i was 17. i was leaving work when i got this BRIGHT idea to rev the motor while it was in N and pull it down into first. i ended up breaking both u joints and carving up my driveshaft real good. so it was a lesson learned. BTW i was taching about 5k when i done that........
