Noise from Transmission

I drive an 85' CJ7. Early in the morning I let my rig warm-up for about 10-15 minutes EVERY morning before I go to work. When it's warmed up, I start hearing this loud ticking noise comming from the transmission (right under my stick shift. I have no idea what the hell this is and it annoys the hell outta me!
I also might add that lately I've been getting ALL KINDS of wierd noises comming from down below my stick. Grinding noises, clicking noises.... Now here's the catch, when I push in the clutch, all the noises go away! I've even been having a REAL hard time shifting from gear to gear too, but it does shift eventually :-(... Any suggestions folks? Am I gonna need a new transmission?

Re: Noise from Transmission

Since it's an 85 I would assume you have a T5, and it has quite a few miles on it. The T5 is not very heavy duty, and after 100,000
miles they usually need a rebuild, or better yet a replace. A common problem on the T5 is the bearing on the input shaft, and yes
the noise will go away when the clutch is disengaged. Part of your shifting problem, though, may be clutch not disengaging properly,
when is the last time the clutch was replaced and the flywheel resurfaced.

Re: Noise from Transmission

I had the clutch replaced, and flywheel resurfaced about 1 year ago! Another thing I should add is that my shocks are gone to HELL. I mean I practically have NO shocks... Is it possible that I have just shaken my clutch to death?

"No" to the shaken my clutch to death,,, You may even have a bad throw out bearing not letting your clutch disengage properly but my money would be on the bad input shaft bearing as they are quick to wear out on some models of trannies. If they go long enough in bad shape they will eventually take out the syncro's and then the gears in the gearbox, (sounds like this may have already happened). just my thoughts on this

Re: Noise from Transmission

Jim's probably on the right track. His insight applies to any manual trans. If it's chattering and it stops when you put in the clutch .... it's usually your input shaft bearing. It's obviously too late ...... but when is the last time you checked the fluid level? I drove my Ford Ranger (4cyl 5 speed) too fast for too long and either threw the gear oil out the vent or .. since it was low .... heated the gear oil to such a state that a good bit of it "vaporized".(no leaks)... topped it off and drove it until the rest of the vehicle died
