I recently got an 89 Wrangler YJ(4.2L, 6 cylinder). When I got it it didn't start. Whoever had it previously had left just about everything disconnected. I went over it and cleaned up connections, re-connected everything I found disconnected and it still wouldn;'t start. I then noticed a ground was sparking when I tried to turn it over, there was a loose ground at the alternator. After I tightened this up and set the timing, it started. It drove pretty well, but most of the fluid levels were low. I topped off the levels and took it out for a spin. I noticed that I had to push the clutch to the floor to change gears. It still seemed to have trouble changing gears. Then while I was out, I couldn't get it out of second gear. I got it back home and checked the master cylinder, which appeared to be dry. Once I topped that off, I was able to change gears easily. I went to move it friday and put it in forth gear mistakenly instead of reverse. Now, I cannot get it out of fourth gear. The pedal feels fine and if I push the pedal in it will start just fine and doesn't move or act like it's in gear, acts as it should when you have the clutch pushed in. So, I'm not sure if this is a clutch issue, a transmission issue or a problem with the linkage. And why did the problem clear when I added fluid to the master cylinder and then lock into fourth gear? Any ideas where the problem is or what I should look at?
