After years of problem free operation, it happened while in the mountains camping last weekend. 04 TJ. 50,000 miles.
Jeep worked fine all day Saturday. No weird shifts, business as usual. Sunday morning while on the way to the trail, it would not shift out of second and the CEL came on. Good thing cause I would of needed 1st gear on that trail.
Generic code P0700 on the odometer. Hooked up an OBDII reader when I got home and got an additional P0605 code. TCM?
Fluid is full and doesn't smell burnt. All connections look good. No blown fuses. I've even unhooked the battery and let it sit for a couple days.
Edit: The light on the OD off button also does not light up.
According to the dealer, I need a DRBIII reader to pinpoint the problem. Conveniently for them, they are the only shop around for miles that has one.
I guess my question for the pros is if there is anything else I may have missed before I haul it to the dealer? It has not been there since new. I've done all repairs and mods myself, but am no transmission guy. Thanks.
