Exclamation Trany trouble

I have 2006 grand Cherokee Laredo with the 4.7 it has been shifting into drive really hard and feels like its locked in one gear while I'm driving. It also stalls once in a while when I stop. If anyone has had this problem I would appreciate some help.

Re: Trany trouble

First thing to do is to get it scanned, to see if any fault code is set. How is the idle speed? A too high idle speed will cause hard shifting into D.
It feels like it is locked in one gear? So you donīt see the rpmīs dip when driving (if it shifts, the rpm will drop a 400-500 rpm). If the TCM (transmission control module) sees a failure which could harm the transmission, then it will put the transmission in limp mode and it will stay in 3rd gear. If the engine stalls when coming to a stop, than it could have to do with the engine idle itself, but also a not releasing torque converter clutch could be the problem. But most probably the scan will tell more about it.

Re: Trany trouble

Thanks I bought a car scanner and your right the transmission control module was sending an error code. Really appreciate the help

Re: Trany trouble

My 5.7 was having trouble for the longest time. Rough idle (like it wanted to die and it did sometimes), delayed shifts, and random surging upon acceleration. Until a few days ago it just died on me and would intermittently start or would just crank or not crank at all.

I thought it was the transmission; however, i knew it couldn't be because I just had the trans installed last week. I also thought it was the the ignition switch, but I replaced that too. I even thought it was the Gear shifter module(which i also replaced because I was almost certain it was it) because the dash would state it was in gears that I knew it was physically not in.

Nonetheless, after countless hours of research online, I took another shot in the dark based on similar symptoms and feedback and determined it to be a bad crank position sensor on its way out. Voila! all my problems fixed.

I know this might not be your problem, but based on what your telling I had similar symptoms to yours ( even limp mode) before I replaced my crank sensor(24$ part). Sure beats a trans rebuild.

Do yourself a favor, I would check all the small things first. (i.e.) input ouput speed sensors, crank sensor, cam sensor etc before taking to a trans shop.

Did the fault code stored point towards the crank sensor?

For me the there was no fault code related to the crank sensor, the problem was so intermittent. Thinking back the trouble started out slowly, sometimes I would start the jeep and it would sputter and die, until one day I drove to the store came back out and it wouldn't start or crank. Eventually after some cooling down the Jeep would crank over, but once it heated up again it would die on me. When I mean die on me, it literally died on me while driving.

It would advise to google symptoms of a bad crank sensor and see if it sounds like you. The sensors are relatively easy and cheap to replace. It took me 5m do the job.

Donīt have problems with my jeep (at least not related to this thread), was just curious if a fault was stored pointing to the sensor.
The symptoms your jeep was showing, where pointing towards the crank sensor. Only strange that it wouldnīt crank (turn) sometimes, because a bad crank sensor will not prevent that. It will prevent it from starting.
