6cyl - 4.0 - Automatic 99 Grand Cherokee Limited - 170k miles.
My transmission was running fine with no symptoms. One morning it suddenly would not shift, it wouldn't come out of first gear. I ran the shifter to 1st, 2nd & Drive plus tried the overdrive button on the stick shift but it wouldn't come out of first gear.
Neutral, reverse and park all work fine.
Oil was clean and full.
Took it to a shop and they rebuilt the transmission, tested and said it worked fine. Cost, 1800 bucks.
However when I drove away from the shop it still had the same problem. Now in shop again.
Could the problem be electrical or some sort of computer module?
It has been having electrical problems for the last 5 or 6 months.
1)No electrical working from steering wheel (horn, cruz control, stereo controls).
2) Driver door electric control buttons won't work when door is open (elec windows, mirror & door locks)
3) interior fan doesn't work. I bi-passed 12 volts to it and it worked. (I believe this is an isolated problem.)
Wondering if it could be same wire bundle or computer mod as transmission if that's the case.
have the same problem?
