So I'm trying to fix the issues with my transmission on my 1990 Nissan 240sx that I picked up a year ago. I haven't drove it with this issues. I pulled apart my
Transmission because it was making noise while in neutral. I found a few problems. also, it looks like this transmission has be opened before.

My main drive gear, Sub-gear, and Counter drive gear are damaged, but what I found odd was the Sub-gear wasn't really lined up with the counter drive gear.
So it messed up the main drive gear. This can't be correct right? Is the sub-gear incorrect because some spots seem to line up and others don't

almost looks like it's on backwards...lol. Without the bearing off it's hard to say. It could be a wrong one (there were so many variations of that transmission that someone could of easily put on the wrong part).

also some of that engagement looks very harsh based on the tooth wear...not only the pointed out damage...

Yes, The input shaft gear has a lot of wear and counter gear. I'm going to replace them. I just wanted to make sure that sub-gear ( the small washer gear thing in front of the gear) was in correct. I was just looking over everything and that really just stood out to me.
