I was thinking about changing from my auto to a manual. I wonder really how much work it is. Does the ecm and pcm need to be changed? I was looking to put a NV5600 into mine but a NV4500 would work to. They have about the same final ratio anyway Just first gear off. I don't do any heavy hauling so. Would anyone like to take on a trade for a auto out of mine for your manual? The trans has DTT part like front drum piston, accumulator, servo, band ratio arm with lever and valve body the t/c is BD. The trans was set to DTT spects for end play and clutch pack spacing. Bill is a very nice and helpful person and so is is family.
