Yes, they are and can rebuild. Also, Southern Gear in Smyrna, GA.

Rebuilding these is actually not that hard of a job. You just need a set of punches, a couple of snapring pliers, a torque wrench, and the manual. The difficult part is finding some of the parts as most are NLA.

What kind of problems are you having?

I can send you a PDF of the manual if you like. Just need to know what year/model gearbox you have FS5W60A or FS5W60L.

thanks all for replies so far!

The issue is in fact finding the parts.
Got the original rebuild, and after it was put in, started hearing grinding noises. I don't do this kind of work, so took it to a mechanic who works MG's and in dismantling he found it needed some new parts. has not been able to locate for several months.
so, my last meeting with him we decided to 'send it out'.

here is a video I posted a good while ago with the original 'diagnostic clues'.........

That is noisy. What parts does your mechanic think you need? Some of us may have them.

Rich, you forgot bearing pullers and having a press doesn't hurt either. My guess is that nut that holds the gear at the end of the countershaft came loose and there is a lot of end-play. Sounds to me like there's bearing damage and probably gear damage as well. If I'm correct about the cause, that gearbox is likely toast. I can get rebuild kits for them, but you can forget about pretty much any other parts except what you might find used. Except for ball bearings (4), synchros (5) and a few consumables like seals, dust boots, and shifter bushings; there's pretty much nothing else you can find new. I think you'd be better off finding a new one. The ones right out of an original car don't always need rebuilding and I don't recommend doing it as a "matter of course". If you do source a new one and decide to rebuild it, have someone experienced with manual gearboxes do it. Run, don't walk from a shop that does mainly automatic transmissions. They seem invariable to screw these up.
