k so i found a really cheap tranny on the parts trader, seller says it grinds 3rd above 8k rpm. what would be needed to fix that grind, assuming it’s only the 3rd gear that’s got problems? TIA!
Rebuild the tranny. Specifically you’ll need to replace the 3rd gear syncro, but since you’re in there you might as well replace them all.
Call around to price how much its going to cost.

so would i just need to put in new synchros, or gears too?
also what synchros would work in a j1 tranny? (it’s JDM) 
Yes just syncros. And I think Bseries syncro’s are all the same, but I’m just guessing there.

rock on. i THINK the dealership is open tomorrow. i’ll give 'em a call. thanks steve. again…you is da man. 
edit: ugh i just checked…they’re open 8:30 till noon. dammit! i wanna sleep in!!!

Hahahaha…just make sure you ask them about syncros. I’m not sure if they are all interchangable.
