Tranny trouble

I have always thought something was alittle funny about my transmision!! Got a 06 2 whelldrive with a 4.7 motor, when I go to slow down I can feel the tranny down shifting, especially to the lower gears, seems to be getting worst. Also have had a couple of times where it will down shift going down a small hill with the cruise on, was wondering if anyone else has had this problem, and what is the solution?? Thanks for the help

Re: Tranny trouble

I know mine has the hill descent feature (4.7L, 4x4) which I feel holding the vehicle back sometimes as I coast down hills.

I thought only the 2008's had the hill descent feature.

Re: Tranny trouble

As 5253 said though, if you're "coasting" downhill with the cruise on, the cruise is dedicated to keeping the Jeep a constant speed. That means up and down shifting as necessary.

Re: Tranny trouble

I am having similar problems with the tranny. It shifts funky when slowing down at stop signs red lights etc. The biggest thing that it has started recently is when traveling down the road with the cruise on. We were on the interstate when it did it the first time it shifts up and down for no reason we were on flat land. It runs the rpms sometimes to almost 6k. So it is going to be looked at tom. I am dropping it off at the dealer tonight. It does this odd shifting at any speed put only with the cruise on of course. I also find it slipping when I first put it into gear after sitting. You put it in gear and nothing happens. You give it gas and nothing. I have had this problem for sometime but the dealer I was going to said they did not see anything wrong and it had no problems. So new dealer same problems we will see what they can find. However, when I was at the dealer last week and described my problems the man was not suprised to hear some of my complaints. So I feel much better about this dealer already. I will let you know how it goes.

I have the same issue with mine - '06 4x4 Hemi Limited. I have had the dealership look into several times and they claim the shifting is "normal" and the tranny is shifting based on my driving habbits (which are pretty harsh)

The tranny went at 850 miles and had to be rebuilt. I still think it has minor issues but get the same "we cannot find a problem" out of the service department. I guess that is why I have an extended warrenty

Re: Tranny trouble

My 3.7 4x4 has hill descent with cruise, I usually cancel the cruise to let it coast.
I also get the trans holding a shift to 6K with cruise and even if I try to upshift, it won't but that's usually only when I'm on the highway.
Yesterday without the cruise it wouldn't shift out of 4th

Hill Ascent control assists the driver when starting a vehicle from a stop on a hill by maintaining the same level of brake pressure the driver applied for a short period of time after the foot has been removed from the brake pedal. The system will release the brake pedal in proportion to the amount of throttle applied. If the throttle is not applied within a short period of time after the foot has been removed from the brake pedal, Hill Ascent Control will release brake pressure.

Hill Descent control allows a smooth and controlled hill descent on rough or slippery terrain without the driver needing to touch the brake pedal. This system applies the brakes to each wheel individually when needed to reduce forward motion while negotiating down steep grades.
Right, that's why I said hill descent with cruise and not all cars have it. All cars will let up but not slow them down.

Re: Tranny trouble

My 06 Hemi Limited does slow me down on a descent with the cruise on in order to maintain speed. I like it.

RIP - Silver '06 Limited; 5.7 Hemi; 2" TerraFlex Lift; 255/70R17 Bridgestone Dueler REVOS, Horizontal Inclinometer, Signal Frog Antenna Ball, Surco Safari 50"x50" Roof Rack, GetLost4x4 bumper, Bulldog 9k Winch, GetLost4x4 Rock Rails - (should have added a snorkel)
