I have my 5 speed tranny and it is totally disconnected sitting in my garage. My 5 speed swap is coming up and I was daydreaming of shifting and I can shift from 5th to reverse. Does anyone else have a 5 speed tranny that is not connected and just sitting and can you try to shift from 5th to reverse? I am just wondering if once the tranny is mated to the motor and ds if it locks it out. I hope so because it may seem stupid but I don't wanna mess up and shift into reverse from 5th. It would be greatly appreciated.
