So I finally got around to dropping the trans on my '92 Talon TSi AWD and took it apart. To my novice eyes it looks to be in good condition, no broken gears, forks or pieces of metal or major shavings, maybe a few tiny case slivers that might have been caused by taking it apart. It needs a good cleaning but that's normal.
The oil, which is still fairly new, maybe a couple hundred miles since I replaced it late last year, is kind of grayish with maybe a tiny tinge of bronze. The magnet had this thick sludge-like goo around it of the same approximate color. I'll post photos of everything later after I take them.
Since the reason for taking it apart was to fix the popping out of 1st issue, I'll start with the intermediate shaft. I haven't taken it apart yet as the bearing splitter I have is too small and I have to order an OTC 1130.
But I took some photos and was wondering what you all think, what's obviously bad and needs to be replaced (beyond the bearings and lock ring of course, and maybe the needle bearings).
It's a little hard to tell but both synchros are clearly shot, with many (but not all) dogteeth totally worn down on one side or the other. I was going to replace them anyway and expected this so no surprises there.
The reverse gear on the slider/sleeve is worn on the pointy side (not sure what the official term is). Is that bad and does this by itself necessitate replacing the hub/slider assembly?
What about the dogteeth on 1st & 2nd? Do either look worn enough to require replacement, or at lease make it a good idea since I have it apart anyway?
Finally, I had the trans rebuild or replaced over 25 years ago by a local dealer. It took them nearly a month as they kept trying to replace this or that, and finally they put in a new trans, which worked fine until this popping out of 1st issue started happening some years ago (at which point I kept driving it for a few months until the clutch wore out and the car sat undriven for 5-6 years, until l started restoring it nearly a year ago).
So I'm not exactly sure what I've got in there since new trans sometimes have different parts even for a specific trans part #. Looking at the invoice (I saved and scanned everything), the new trans part # is MD995651. However at some point, whether before or after they put in the new trans I'm not sure, they put in a new 2nd gear, part # MD743190, new 1st/2nd hub/slider w/synchros assembly part # MD743534, and a new intermediate shaft, part # MD740193. So it's possibly a bit funky in there. Or not.
Any idea which shaft, gears and hub/slider I have, based on these photos? And anything else look bad enough to replace?
