I have a '95 YJ, 4 cylinder with a standard transmission that I bought, used, from a gentleman in late December 2010. It has over 202,000 miles on it, had to have the head gasket replaced as there was a 3/4" gap in the old one and I was losing compression and two cylinders weren't firing. Just a couple weeks ago the oil pan gasket and the oil sending unit blew. It ran fine after some work.
Most recently, namely today, it will not engage when I try to shift into reverse. I was able to back out of the garage this morning with no issues, but in the fifteen minutes it takes me to drive to work, it will no longer engage. All the other five gears work fine.
