I've had this M2A4 Prelude trans sitting around for about 3 years now. It was removed from a customer's car because of no reverse engagement and I installed a h22a LSD trans into his car. He told me to just keep this trans. I've decided to take it apart and I can't figure out what kind of diff this is. There is no bar indicating Non-LSD and it is not completely hollow like a Honda LSD. Anyone know?
