SOURCE: 94 jeep grand cherokee will not shift into overdrive

My 97 Jeep Grand Cherokee was doing the same thing. I changed the TPS ( Throttle Position Sensor) Now it is great goes into overdrive fine. It is really easy to change.

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...


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.

1999 jeep grand cherokee tacometer reading???


Cruising rpm even after the OD has engaged has a lot to do with the differential gear ratio and tire size.
There will always be a variation between different vehichles due to that alone.
To see if the OD is working, at about 50mph, lightly touch the brake pedal. If the rpms increase for a moment then the OD was engaged. (touching the pedal momentarily disengages it...good thing to know when hill climbing!

My manual 5 speeds only makes bearing noise when at highway speeds . repairman says it is a bearing but i thought a throw out bearing only makes noise when pushed in ,


Are you sure hes not talking about a wheel bearing for your front wheels. A throwout bearing will sometimes make nosie like a rattleing if it is not engaged. When engaged it will sound like a roaring nosie. I would check in to were this nosie is coming from first.

94' jeep grand cherokee trans. delays in reverse


Hi ray_c_brown, This pause is determined by a time lag test, and you can check this yourself with a stop watch.Engagement time in "D" range should be a maximum of 1.2 seconds and the engagement time for reverse should be a maximum of 1.5 seconds. So with your vehicle warmed up and assuming curb idle speed is correct set the park brake,make sure ac is off (air cond) shift transfer case to 2H or if it is a NP249 transfer case leave in 4H,put your vehicle into neutral and set your stop watch shift to Drive and record time repeat this a couple of times and do the same with reverse,as you said the delay is with reverse so if it takes longer than 1.5 seconds here are a few things it could be:shift cable adjustment,low line pressure,worn direct clutch, first/reverse brake worn or a worn or damaged overdrive clutch.Hope this helps you good luck :)
