Having problems with your 1999 Jeep Grand Cherokee ?
Replaced transmission seal then on 2 different occasions going down highway at bout 65 to 70 miles hour transmission kept shifting btween overdrive n drive come to a stop n take off didnt do it again fluid level fine 1999 jeep grand cherokee laredo v6
Computer controlled transmissions can get confused at times, from my personal experience. If the problem doesn't happen again, I would ignore it. If it happens all the time, it's most likely the transmission computer. Other things could be the shift linkage, engine vacuum leak, speed sensor, etc... Hope this helps.
