Clutch

[Omarmartinez33]

I’m having a hard time shifting into different gears. I have to double shift to basically get into the next gear. Also have a hard time going into reverse. It has shifted well before this so idk what the problem is.

Can you put it in gear from a standstill?

Yes

This tranny issue was left hanging. Any ideas?

It is curious that no one wanted to venture an answer to this question when originally posted in April or a few days ago when reposted.  I don't think the poster is still active on CC.  It seems like a legitimate question. I recall decades ago if a car or truck jumped out of gear, the first thing many did was put a heavier oil or even grease in a straight transmission. I assume  an MJ came along way too much later for anyone to have done that. When I was 15, I would drive a big old 1948 Ford truck with 8 foot slatted sides around the county with two or three mules loaded.  The old truck had a ragged transmission and it would jump out of gear. . The solution was to drive with one hand and hold the floor gearshift with the other hand to keep it from jumping out of gear.  It was not as much trouble as it might seem, because I started driving at 8 years old off road. I grew up in a small town, but  my Dad raised tobacco on the side. Mules were used much later than with other crops because they could maneuver in tighter places better than a tractor. I still have vivid recall of walking behind a mule and have it fart in my face. Then  take a dump. Piss like no tomorrow.  Mules did not know about political correctness.A friend's father ran the school bus repair yard and I learned from him how to get a transmission out of gear if it seemed totally locked. I also learned how to drive without using the clutch and prided myself on how smoothly I could shift even the most ragged transmissions without using the clutch and without any scraping the gears.  That skill came to good use  later when a friend and I went to Datona for Spring break in college in his MG Midget.  Things kept going wrong with the car and the local dealership could not manage to get things fixed.  When the clutch went out, I drove the car 230 miles from Datona, FL to Savannah GA with the clutch not working at all. Some one in Savannah fixed it and we made our  way back to VA.  Now after all that, does anyone want to give the original question a try?

That's an interesting story.

 

The problem with this thread was the described symptoms didn't fit anything specifically.  Trouble with one or two gears is typically synchros/wear or an actual internal failure (you need to rebuild, that's that).  Trouble with all gears is typically the clutch hanging up, or some other reason the input side is not being disengaged, however this problem is typically confirmed by trying to put it into gear while not moving (it will not want to), and he says that isn't an issue.  That leaves operator error, or operator error induced by tolerance stackup, as in he's not actually getting the clutch disengage while moving.  I'd feel that likely is/was the case, worn bushings in the pedals/linkage, carpet or floor mat buildup interfering with the pedal, a weak master/slave and soft hose, along with a worn clutch and dry pilot bearing, will mean you have to very deliberately push the pedal to the FLOOR in order to get a decent disengagement to allow gear change.  The other factor here is we don't know what style of driving/shifting he follows, people who regularly shift without the clutch will likely not notice clutch issues (even when using it) as they will instinctively rev match instead of making the clutch work, however these people tend to notice synchro issues much faster.

 

If OP had returned again to say "I tried this or that, or it only does it this time" and bumped it again, people likely would have replied.

 

Is your transmission doing the same thing?

 

Edit, above comment had assumed people would do obvious things like check fluid level and condition, I probably should have told him to do that the first time around but it seems like a no brainer to me that when a component acts up you should see if it has oil in it and if the oil is not glitter or grit.

Dirty, you stand as a man alone that addressed the issue. Not once but twice. I realize that not enough is known from the original poster but your answer is expansive and provides some theories about a truck transmission that we probably will not know more about.  I have no tranny issues but I am drawn to manual transmission malfunction mysteries and electrical issues. I had wondered if there might be a mechanical issue with the shifter or something gummed up or blocked internally. I assume he meant double clutch when he wrote double shift.Your ideas make as much sense as any offered.  Lol.  Thanks for your answer.

No, not really. 

 

 

Masters, slaves, TOBs, pressure plates, clutch discs, shifters, nylon bushings, they all wear out. 

 

One must be present to discern. 

 

One must have general mechanical ability and knowledge and aptitude. 

 

Whether it takes me an hour or a few minutes, with some effort I can always work through a problem or at least determine what my problem is. 

Getting information from some of you is worse than pulling teeth, too much effort, has become a bore. 

 

 

And further, in my experience, and in the experience of others, moving to the Hurst/Core solved my shifting problems. Hurst/Core will cost you $250, Jeep people are cheap and I get tired of repeating myself to deaf ears. 

 

If you have an AX15 or an AX5/4 and you have a shifting problem and you know for a fact it is not in the case/gears-

 

Replace-

Clutch disc, TOB, pressure plate- LUK

Master/slave unit- Mopar

Shifter- Hurst/Core

Fluids/seals

 

And you'll be good for another 100K++++

 

Now get off your @$$ and get to work.
