I recently did a few different projects on my 2000 Jeep TJ 4.0L Automatic, one after another. Changed out radiator (old one was leaking), transmission pan (old one dented), cleaned battery terminals, new spark plugs and engine oil change. While doing this work I was able to start the jeep in park / neutral with out problem.
HOWEVER, my issue started a few days later when I decided to go on my first drive since doing this work. I started my Jeep and put it into R, to which I was able to move about 100 ft before the engine stalled, I started the Jeep back up and drove it 100 ft back into the garage and turned it off. A few days later I went back out to the garage to investigate what the issue was. I started the Jeep and put it into R, it stalled right off the bat. I started it again and put it into drive it stalled immediately. The Jeep can only start and stay running in N or P, it idles well and will not cut out in those settings, I give it gas and the engine responds to it well. After a few times of the engine cutting out the check engine light came on. I do not have a reader but have one being shipped overnight from Amazon. Ill be using it to read the code and will report back first thing in the morning.
After reading several articles on this website I decided to take the throttle body off the Jeep and clean it, the IAC control + housing. After re-assembling, I started the car and till had the same stalling issues when putting into gear. I did some more reading and found out that some people were diagnosing this same issue as a Torque converter problem on their Jeeps.
Once I read more about what the Torque converter it had me thinking that maybe I had caused this issues + broke the TC when working on my transmission pan. I say this because when replacing my trans fluid pan I opted with the new high cap skyjacker pan as it was the only pan I could find for my transmission. After reading reviews I was told it would fit fine. However I found that in order to get this pan to fit in-between the transmission and the skid plate I had to remove the skip plate bolts, which I found out to my amazement was also the transmission mount. The mount dropped with the plate for a while before I was able to get a jack to lift it back up. After getting the transmission pan in, I bolted the skid plate back up to the frame. This period where the transmission was un-supported has me thinking that maybe I had put to much strain on the TC and "locked it up".
My questions to the group would be:
1. Do you agree that this could be a torque converter issue?
2. Could I have damaged this part when I changed my transmission pan and accidentally left the transmission un-supported?
3. Any advice on what you would do next to start diagnosing or fix the problem?
