Transmission or Clutch?

Alright so I have been doing a rebuilt and yesterday I fired it up and it started fine. I didnt try to drive it at all yesterday, I just let it run for a little while so that I could make sure there were no fluid leaks and things like that. So I go back out there today and start it up to test drive it some.

Here is what it does. Before I moved it I cycled through all of the gears with the clutch in just to make sure everything was smooth and it was. So I put it in reverse and back up about 20 yards. I had to do a 3 point turn to get it out of my driveway so after backing up some I stop, push the clutch, put it in first, and pull forward about 10 yards. I stop again, press the clutch, and put it in reverse. As I let go of the clutch nothing happens. The jeep wont move. So I try to put it back into 1st and it wont come out of reverse.

I checked and changed the transmission fluid, I bled the clutch, and I tried rocking the jeep and taking it out of gear and still nothing . Any ideas on what could be going on here? Its an 88 Wrangler with a 4.2L 6 cylinder and a 5 speed manual transmission.

From what I read, it is stuck in reverse? First thing I would check would be linkage. How is the feel of the clutch pedal when you depress and release it? Post up and let us know.

If u can shift it out of gear with your jeep turned off then I'd say something with the clutch. If I won't go out when its turned off then probley something with your trans is not right.

You said you did a rebuild, what exactly did you do? Did you do anything clutch related?

No I didnt do anything clutch related...I do have an update...it will go into reverse and the jeep will back up just fine...however, it will not go into any other gears...so im thinking its time for a new transmission or a rebuild of this one...

Quick question...I have heard a lot of bad things about the ba10/5 and quite a few good things about the ax15..would the ax15 be a good transmission to swap in? and if so would it take a lot of modifications if any at all? I can get one from a you pull it place for about $130

AX15 is a good transmission and that is a good price, however, make sure it has the same number of splines. Also, get the TC with it, you may have to have the driveshaft shortened or lengthened. Don't know about transmission mounts or whether the holes will line up where the transmission bolts to the engine. Also, it would be a good idea to get one with the external slave cylinder. Lots of things to think about before trying the swap. Maybe someone else will chime in.

Throw that peugoet piece of junk away. It is not worth the aluminum it was made out of. Pure junk.

That being said, the AX15 is a good tranny as CMike357 said. Couple of things. If you reuse your transfer case, which assumes that the output shaft has the correct splines, it will be clocked lower than it was, which means you will have to modify your belly plate.

It also means that your transfer case shifter will also be clocked lower, as the bolt holes are different from the ba5/10. You will have to modify your floor board about an inch in the left rear corner.
This sucks, ask me how I know.

3rd. As CMike357 said, if you can, score one out of a 93 or up, as they had an external slave cylinder. You will also have to replace your master cylinder, but you can get the whole master/line/slave assembly from rockauto for just over $100.

If you get one with an internal slave, you will not be happy. I've had to pull mine 4 times in 4 years due to the O-rings where the lines go into the slave cylinder going bad. To do this, you have to drop the trans. Big PITA.

In a nutshell, If I were investing in an ax15, I would get one out of a 93 or newer wrangler, with transfer case and shifter included in it. You can use one out of a xj/zj, but I'm not sure how the clocking and I think the shifter assemblies are different on those. My zj has a different shifter, but I haven't looked at the shifter assembly on it to see how different it is.

Hope this helps.

21 spline for automatic and 23 for manual trans? If I remember correctly? Been a while. Everything everyone else said. I'd upgrade to a newer external slave for sure. So much less hassel. I'm almost positive the mounts are the same too.
