Gears do not shift properly sometimes

Shifting to any gear gets troublesome sometimes . Does not happen all the time . I feel it happens if I am in stop and go traffic. But sometimes it has happened in normal traffic also. All fluids are fine, I did top off using brake fluid DOT 3.

Couple times it would refuse to get into any gear and I was holding up traffic .

Took it to a jeep dealer, he did not do any diagnosis , but concluded that clutch system needs to be replaced and gave me an estimate of 1200.

What should I do ? Advice from the experts.
How can this be diagnosed properly ? Would a clutch need to be replaced after 69k of mostly highway miles

Nomad-sal- Hopefully someone answers because my 97 is doing the samething right now. Also- I have noticed that when I am parked and out of gear, there is a low pitch whining sound and my RPM's dip. But if I push the clutch in it is quiet. Does yours do that also?

When standing still at idle with clutch depressed will it go into 1st? Or does it grind its way in? Once you are in gear get it into 2nd, then idle down. Brake as hard as you can, don't push the clutch in, make it stall. If you are stopped and in gear, your clutch is slipping and worn... But from your hazy description, my first thought would be a bad slave or master cylinder.. keeping the clutch from disengaging.. A good test for this would be rolling down a steep hill in 2nd or 3rd, no throttle. Push the clutch in. Can you shift it? When your drivetrain is torque locked it should be just as hard to get it out of gear as into gear.. Don't trust dealerships.. And yes, if a driver is hard on his jeep, the clutch components can fail, even with less miles than you have... Did you buy it used?

That low pitched whining is normal, my throw out bearing has been noisy forever... well at least for the past 85,000 miles and I'm at 93,000..

Thanks for the response rubicondon53. Answers to your questions below

1)When standing still at idle with clutch depressed will it go into 1st? Or does it grind its way in?

Ans) Most of the times it goes into 1st, sometimes it does not, it either grinds its way in and I feel that I am forcing it to 1st. Occasionally it refuses to go into 1st or any gear when standing still, for example at a red light. Then I have to shut off the engine, start is again, then it shifts to first gear.

2)I will try your rolling downhill test and post back. So it shifts, while no throttle, what does it mean ? Does that mean the master is bad ?

3) I bought this NEW. so I have been the only driver on this jeep past 12 years, barring the rare occasions when my wife has driven it, when her car is out for service

@chargervp - I have not noticed that whining sound while idling .

That low-pitched sound is not caused by the throwout bearing, it is the normal sound of the transmission's input shaft & gears being spun by the engine. You can verify that by stepping on the clutch & hearing that sound go away.

Ahhh, any other gear as well as,,, check clutch fluid level 1st, should be at least 3/4 full... Unfortunately it will probably be ok, which indicates the need for a new master/slave kit, about $170,, the kits are a pre-bled sealed unit.... In the old days, if one failed the other was close behind, it's nice that Mopar designed the two to be installed together... That's my best advise, but I'm always willing to be corrected... BTW, do you live where it gets extremely cold? I was brought up in very cold winters and the hydraulic systems on our tractors needed rebuilt or replaced often.
