CJ5 transmission issue

Bought a CJ5 a few months ago, test drove it but it needed a complete fuel system overhaul (carb, fuel lines etc.) Got it running and backed it out of the shop to check the carb wile running. When I got back in a minute later the jeep would only creep forward at full throttle. Not sure if the clutch is completely engaging. Checked the transfer case fluids and everything seems to be in order. Not too sure where to go from here before completely dismantling the drive train. Has anyone had this problem or have any possible solutions?

Welcome to the forum! I'm just across the road from you.

Engine is running strong, it sounds like. And rpms are doing...what? Options are, from another recent thread:
1) You're in the wrong 4wd gear - i.e. 4Lo - check to make sure your in the right gear
2) Your clutch is burnt out - does it do the same in forward and reverse? You could maybe disconnect the rear driveshaft, throw it in 4Hi, and see if it does the same thing.
3) You spun your rear hubs - None of the above lead anywhere.

How's the clutch pedal feel when you press it down?

Won't engage? Like you engage the clutch and can't shift it, or it grinds too much when you try so you stop before you kill it?

Lumpy, clutch pedal is consistent but soft, re-worked part of the clutch linkage attached to the frame as the problem came up. Jeff, The clutch pedal doesn't seem to change the dynamic, weather the clutch is depressed or not you can shift the transmission into any gear with only a small amount of resistance and grinding.

I agree with Lumpy. Just replace mine and it was sort of the opposite - no matter how hard I pushed on the clutch, regardless of how it was adjusted, the pressure plate wasn't doing much of anything.

Any estimates on how much time and cash this might take to fix. I've replaced similar parts but never on a jeep and don't have much time during the summer to dedicate to a problem like this (I farm).

How do you know for sure it's the clutch?
How do you know for sure it's NOT the tranny?
"We" sure don't, and WON'T, till the tranny is out.

Assuming it's the clutch (pressure plate, etc.), a clutch kit from Napa runs about $135. Plan for a gallon of 90 weight GP4 to refill the transmission and transfer case, about $25. Not having done it before, say 4-6 hours to pull it all apart and about the same to put it together again. Of course, if that *doesn't* fix the problem, then it'll likely have to come apart again to dive into the tranny. Figure $80-$150 an hour at a shop (but they'll be much faster) and you'll still save a few hundred bucks doing it yourself - and learn something new!

Have'n done this many a time. Plan on the entire weekend from early Sat morn.
Hope you have the alignment tool for the clutch disc. You'll also will NEED a rolling floor jack. One with a tranny-mount adaptor is a big plus.
Get a top line (Gold Line)clutch from NAPA with new pilot bearing(roller)and Throw out bearing.
The biggest PITA is get the tranny back in!
Don't forget the band-aids

Most clutch kits come with an alignment tool. I would split the xmsn and transfer case to make it lighter. You should have an inspection plate around the xmsn in the tub pull it for more room. By the way check your clutch linkage sometimes it causes problems.

I know NAPA does. Not sure about other outfits.

New thought. Anyone with a cj5 have a diagram or picture of the linkage from foot pedal to the arm leading into the side if the bell houseing? From the adjustable cable link and link arm I may be missing a spring connected to somewhere foreword of the linkage. But where to connect this spring and how long it is I do not know.
