Clutch troubleshooting

The clutch/gearbox in our Wrangler has acted up for years. It doesn't like to go into 1st or reverse when sitting still. It doesn't grind, it just takes a lot more force that it should. Often I put it in another ,taller, gear and then into 1st as I try to move forward and that works for getting into 1st better.



I and the wife bled the clutch last weekend. It took about 6 "squirts" to have nice clean fluid come out. I did this because the play in the pedal was more than the 1/2" shown as the spec in the manual. At one point, the pedal play felt better and it shifted OK, then I hopped in to move the Jeep back to give be a clear shot to hose off the brake fluid from the drive way. ( The bleed valve is so stubby, I couldn't get a hose on it and still turn the nut. ) When I went to use the clutch it felt less stiff and the play seemed large, but it shifted alright. As the week went and I drove it every day, the pedal git firm again and it now shifts as poorly from the stop, as it did we we started. Shifts just fine while moving.



If the darn slave cylinder wasn't buried in the bell housing, I replace it and the master at the same time.



Anyone been down this road ?

As the years go by the clutch pressure plate fingers can weaken and create that symptom.

Plus, new parts always aren’t good performers.

By now, you also have worn bushings. You may have several aging issues at the same time. There are two bushings inside the shift tower: a 'ball seat cup' and a shift rod cap that can cause a loss of 'throw'. Also, the linkage bushings (under the boot where the linkage connects) can aggravate shifting as they wear out. All simple fixes, and about $15 for parts. With yours being a '92 I'd do that anyway...

Guthans,


Our Wrangler has about 86K on it, so it's low mileage for a 92. It feels solid and not wobbly, when I shift it. If I hold the clutch in for a good bit, or pump it 3 or 4 times, it shifts into 1st. It shifts fine once moving. I would expect that worn bushings would feel sloppy.



Fishadventure,


It is possible, I guess. I know I've had the gearbox off to do something, but it's long enough ago that I don't recall if it was a clutch swap or slave cylinder change.



Sounds like a transmission jack in in my future. That transfer case makes it really hard to handle easily. Very side heavy.

Wouldn't exactly be wobbly...it just limits throw and that is particularly bad on first gear. 2nd is a 'pull' and not so much affected; 3rd/4th get canted and don't suffer because of that either. I'm just suggesting you think on it since you'll be dropping the tranny anyway. I would think the internal slave is to blame for the major portion...which is why a swap up to the external slave could be a good long-term plan? Have you got a BA tranny in there?
