WK sputters around 30mph and wont manually shift
I've got a 2008 Grand Cherokee w/48k miles. Recently I was driving about 30mph and the car would not automatically shift. It felt like it was stuck between 3rd and 4th gear and just sputtered. Also I am unable to manually shift when that happens. The only way to fix this is to stop the car and restart it.

Ever since my car has driven diffrently. Almost as if im missing the 1st gear. When manually shifting 1st feels like 2nd, 2nd like 3rd etc.... It also doesnt always automatically shift to a lower gear when slowing at a stop light like it use to. :(

Anyone had or heard of this problem? Would love to figure out before taking it to Jeep.

Re: WK sputters around 30mph and wont manually shift
it sounds like you have a trans fault putting the trans into limp in mode. sometimes the no manual shift is the electronic shift module fault that requires a new "shifter bezel" to repair, and that may be able to put the trans into limp in (not sure though). Also consider the no shifting will happen if it is already in limp in, it goes to a preset gear and wont change out.

Thanks for the quick response!

Limp in does sound like the issue im having. Is the only way to find out why it's being put into limp mode, to take it to Jeep service?

There's no check engine light when the problem occurs- so a code reader wont do much....?

Thanks again!
