There is a possibility my original 4-speed may need a rebuild. It is my understanding that rebuild kits for the type "A" transmission are NLA, at least in the US. Some questions for our talented membership:

Are any of the components of the "B" kit usable in the "A" transmission?

Has anyone identified susbstitute components - bearings, bushings, synchros, ...etc.? Roadster parts?

Any thoughts on where else to search for a type "A" rebuild kit?

I really want to keep my driveline orignal. Swappng to a type "B" transmission is undesireable due to the potential for damage to the console and underlying body to accomodate the change in the shift rod location.

I'm open and welcoming to any comments, suggestions and recommendations.

Thanks,

Jim

EuroDat has written a bunch about rebuilding transmissions. Here's one link from Tech Articles. The Resources area is really hard to get through, can't figure out where things are. Really just need a long clean list of every title in the area. Had to use Google to find it. There might be more out there. Search EuroDat's name.

@jfa.series1 I've had good luck getting all the parts through amayama, partsouq or nissan parts deal. You'll have to assemble the kit yourself, that's what I did.

If the problem is synchros grinding it might be worth a shot to try Pennzoil Synchromesh. If it's bearings that another story. If it's both try the Synchromesh to see if it stops the grinding and put in new bearings if you can't find the synchros. Some thoughts. You did say possibility.
