This idea has been lingering the back of my head for a while, but I want to get some more definitive information on the subject. I have found that there have been a few people that have swapped their "B" transmission to a "C" transmission, and I have also discovered that rebuild kits for the B series transmission are difficult to source. I have been thinking about this because my truck ('86 720 4x4 with a "short" transmission) really hates going into reverse, like, really hates reverse. I come to a complete stop, put it in neutral, clutch in, clutch out, clutch in, then slowly, and I mean SLOWLY feed it into reverse. I feel the gears catch, and eventually it goes in, and that situation certainly doesn't give me any warm fuzzies. My worry is that eventually there will be some sort of catastrophic failure and my transmission will be toast. My questions are as follows:
Should I be concerned about my reverse gear? To my knowledge it is an unsynchronized reverse gear, so maybe this is just normal operating procedure.
If I need a new transmission, and elect to change from a "B" to a "C", which vehicles should I source my transmission from? It seems a lot easier to source a rebuild C than any condition B.
The B and C are two different lengths, so some driveshaft modifications will need to be made. Does anyone know any details on that?
I haven't driven my truck for a few months because I have been in Germany studying abroad, but this is just something that was in the back of my mind. I haven't seen a Datsun anything since I've been out here, so I am on the forums almost every day because I miss driving my 720 so much. You guys are giving me my fix until I get home at the end of December, so much appreciation for that.
