Transmission/Clutch Problems?

Hey guys, wondering if I could get some ideas from you. I have a 94' YJ with a I-6 in it and all stock parts (no engine, trans, gear swaps or anything). I will try to explain it the best I can but please bare with me because I am not the most mechanically knowledgable person by any stretch of the imagination.

Over the last 2-3 weeks I noticed a little problem shifting into 3rd and 4th gears. When shifting faster than normal (like getting onto the freeway to merge into traffic quickly), I noticed a slight grinding (still went into gear) that wasn't there before. Slowing down the shifting (like you should be) everything was fine and no problems or grinding.

Fast forward to today and there was no problems.. yet. I pull into a parking lot thinking all is good in Jeepville. Later, I come back out put it in reverse to leave... doesn't quite go in so I go to first gear, let off slightly on the clutch to move forward slightly and back into reverse thinking everything is lined up. So now is the were everything gets hairy...

1. start to back out of the spot and almost feels like the engine is hesitating. I was thinking maybe it was just the fact that I need to change my O2 sensor (~105K miles) and was thinking maybe it was related to that.

2. go forward and am in 1st gear, I hear (for the lack of better terms) what sounds like a baseball card in the spokes of a bike, but on a larger metalic scale. I immediately pull into the next open space in the lot.

3. if I start out in second (know its bad) everything is fine until I go to press the clutch in, and I hear a knocking. The knocking sounds vaguely like it is the throw-out bearing recalling from the past problems I have head with other non-Jeep vehicles.

4. i am sitting in the parking lot still, and I hear the bearing-like noise coming when the clutch is press fully to the floor. As soon as you let off, it goes away and all "sounds" normal.

5. i go to pull out and am going about 15mph in second gear hearing no noise. I let off the gas without pressing the clutch at all and I hear the noise again until it slows to about 5mph.

6. finally figuring I need to get it home, I pull onto the back street and accelerate through 2nd gear w/o letting off gas or pressing the clutch, and shift into 3rd gear... no problems, no noise.

7. same goes all the way through 3rd and into 4th gear. Shifting in 1st and 2nd you can tell there is defiantely something wrong. Shifting from 1st to 2nd is almost impossible and grinds really bad which is why I started out into 2nd to get it back to the house. (huge eletrical storm coming, no tops no doors)

Now... I am just wondering if this triggers any ideas from you guys who are more mechanically knowledgable than myself. I am going to have to take it into some place since I don't have the tools nor the knowledge to get into pulling a transmission to check out all the possible causes. I figured by asking, at least I could go into the local place with maybe a little knowledge so I am not taken hopefully. I definately appreciate any help in advance. I am taking it in and have yet to find a local guy who is knowledgable on Jeeps. [img]images/graemlins/ooo.gif[/img]

Thanks!

Re: Transmission/Clutch Problems?

Wow! Your symptoms sound as simple as a throwout bearing going south, but as bad as a bearing inside the transmission.
My gut feeling is it's the clutch itself. A spring's come loose or broken, causing it not to release and making noise.
No matter what, it'll have to be taken apart and looked at.

Sorry it isn't something simple.

I'd tow it if you aren't going to do it yourself. Trying to drive it like that if it's the trans could do lots of expensive damage.

Re: Transmission/Clutch Problems?

I agree.. drop the tranny...
my vote is the pressure plate, but the plastic throw out bearings werent very impressive.

Re: Transmission/Clutch Problems?

The T/O bearing is plastic? Wow!
I've heard the slave cylinder is plastic too.

Are there "real" replacements available or do we just have to replace them every few years?

Don't trell me the pilot bearing's made of Plaster of Paris.

Thanks guys!

I couldn't believe the TO bearing was plastic either; guess I just expected something a little stronger from my Jeep. [img]images/graemlins/blush.gif[/img] [img]images/graemlins/grin.gif[/img]

I took it into a local guy who was working on a friends CJ, so I feel a little better letting a stranger work on it... even though that doesn't mean a thing in reality, lol. Anyways, they are putting in a new clutch kit and I am keeping my fingers crossed.

BTW... that sure was a long walk home on the shoe-leather express! [img]images/graemlins/shocked.gif[/img]

Re: Transmission/Clutch Problems?

In case anyone was curious...

Got my Jeep on the way back to the house (AAA [img]images/graemlins/frown.gif[/img] ). The guys at the shop said the input shaft was going every which way and apparently wore some grooves in the pilot bushing. The TO bearing was completely ready to be replaced and the pressure plate just fell apart as soon as they lowered it.

Anyways, looks like Monday I get to visit the transmission shop and have more fun. [img]images/graemlins/chair.gif[/img] [img]images/graemlins/spank.gif[/img]
