Trans tranny noise

[jsherman@brockmanheating.]

I read a post a couple days ago that made me join the group. I also have a whine in 1st,2cd,and 3rd gear. goes away in fourth.
I have a 4 speed manual. btw 1984cj7. Just wondering if that ever got figured out? I can actually feel this in the shifter, so I think its in the tranny. checked all fluids already. Maybe this is normal?

Check your rear axle pinion bearing, years ago I thought my Transmission bearing was shot and it turned out to be pinion bearing

also recheck the actual Transmission plug for fluid level. I have known mechanics and owners to confuse the Transfer Case as the only fluid site and miss the Transmission . Not saying you have, but I've known it to happen with terrible results that didn't need to happen. Good luck, noises of unknown origin suck

My first thought is a bearing. In 4th gear, the input shaft is locked directly to the output (1:1). In other gears, you are transferring power through the gears/shafts. You didn't mention if it does it in reverse also. But if it's a bearing, I would guess it would.
