I just took apart my last transmission, and I carefully documented the disassembly with notes and pictures. I did it so I could put one back together, but I might as well post it here for all to benefit from. It is not intened to replace Red-Beard's article, more to supplement it. The parts diagrams and Red-beard's article are not enough to turn a pile of parts into a transmission. (There are three similar tapered washers that are all different thicknesses, for example) You either have to just know where everything goes, or take very good notes while disassembling. I did not fully disassemble the transmission, just the most confusing parts that usually have to come off. I left a bearing race on the input shaft, and a bearing on the pinion shaft. I did not remove the differential. Without further adoo, (I don't even try to spell french) here's step one:
1. Drain the gear lube! Very important! Here's what happens when you don't: Attached image(s)
