Mayolives Posted August 24, 2020 Share Posted August 24, 2020 (edited) There was a transmission repair shop advertising here on the opening page. I believe it was in Charleston, SC but I can't remember their name and haven't been able to find it. Does anyone remember who they were? I have the 5 speed out of my 79 280zx and pulled it apart to find out what was making a little noise in 1st and 2ed. The gears look good but one of the bearings is in really bad shape. I have a rebuild kit from Zcar Depot with all the bearings, syncros, seals, etc but I've decided not to tackle it myself. Does anyone have a recommendation of a good shop that knows these gear boxes? I'm in SC. Edited August 24, 2020 by Mayolives Quote Link to comment Share on other sites More sharing options...
Mayolives Posted August 28, 2020 Author Share Posted August 28, 2020 Answering my own question! The transmission shop that advertised here is Alpha Transmission. I called them, spoke with the owner who told me he didn't advertise here on this site and the he "didn't fool with old Datsun transmissions" Too much! So here I go again, off into another adventure rebuilding it myself with the help of my FSM. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 29, 2020 Share Posted August 29, 2020 (edited) I don't know what kit Z Car Depot is selling, but I've heard bad things about the cheapo RPM kits, and my friend had hers rebuilt 3 or 4 times due to bad synchros with that kit. It's been at least 20 years, so thinks may have changed, but I think factory Nissan synchros was the answer, the bearings in the cheap kits were fine buy synchro rings weren't up to snuff. EDIT--the other tricky part was the nut at the end of the mainshaft. Seems to have a propensity to loosen, despite being staked. My plan with mine was to tig weld the nut to the shaft in a couple spots and hope it didn't warp the shaft too much. Wonder if you might be able to tighten and then drill a hole and put a roll pin through to keep it from moving.

The parts are made in Japan so I feel ok about them. It's too late for me to search but I thought the parts fron Nissan were NLA. As to the mainshaft nut, I'm aware of it's potential to losen. I have a new one to use and the original one was still tight when I removed it with 144k miles driven. Perhaps the problem is how it's installed by the rebuilder? Fingers crossed!
