Tranny light came on on dash the other day. My ODB-II scanner showed P1698. Looks like you get that code when there is no communication from the TCM.
It still seemed to be shifting fine...I was about 10 miles from home and running up and down hills on the way and didn't notice anything weird. Coincidentally (???) I just had it in the garage for tires, alignment and and free oil change. I was wondering if the garage somehow knocked something loose so I unplugged the TCU harness and plugged it back in.
Tranny fluid was changed a little under 2 years ago before I drove across country. I usually do that every 30K, so still have a little while. Levels are fine. I reset the code, and it didn't come back on on the 12-mile trip to work, but it came back on when I went out for lunch. I also noticed that the speedo needle was randomly bouncing around, but no pattern to it with the shifts or anything.
Looks like TCMs are ~$35-75 on eBay and my dad has a few junker XJs at his house...just not sure how interchangeable they are year-wise or what years my dad has. I think one is a 98 or 99 and the others are older. Anything else I should check into? Thanks!
