Has anyone tried rebuilding one of these transmissions? I have a transmission I want to use that broke a 3rd gear synchro I think. As far as I can tell and going by the book, I've got to take everything off starting from the drive shaft side taking apart the entire thing in order to get to it. Right now I'm stuck with a large lock nut on the main shaft that you need a 1 1/2 foot deep socket to get out. I looked on mazdamotorsports.com and couldn't find it. If anyone has delt with these things, how did you get that thing off? Unless there's a way to get at the sychros from the other side, but as far as I can tell you'd have to take out both shafts at the same time, and that's not happening unless this lock nut comes off.

The lock nut I believe is holding in 5th gear and is in the 5th gear casing of the transmission. Has my do it yourself strategy hit a road block?

Thanks
