Transmission Manual

Hi, I have been working on a 93 Mazda B2200 and am now starting to rebuild the transmission. From what I can tell it is a model M519, but I have not been able to locate a workshop manual for this exact model. The closest manual I have found is for a M15M-D. Everything physically looks the same, but worried about internal measurements and such. Is there another manual I should be using?

Try this...

That's great, thanks much!
