Any guesses as to why the manual transmission would be noisy in neutral, 1st, 2nd, 3rd, and 5th? It only sounds normal with the clutch pedal engaged, or in 4th gear.
Shifts fine. Drives fine.
I thought it was an internal bearing of some sort, but it's become more prominent and obvious where...
I found this pretty nice looking 99 trooper with the MUA-5 manual transmission for sale on Facebook marketplace in Bessemer, Alabama for $2,650. Seems clean. It would be cool if it went to an enthusiast!
