Hey guys,

New to the forum. Have been searching and reading a lot of posts and replies. I have a 2003 Jeep Grand Cherokee 4x4 with 4.7l. Bought the jeep with it in limp mode. Replaced solenoid pack and both input and output sensors. Cleared the codes and took for a drive. Wouldn't shift out of 1st with p0731. Pulled input and output sensors out and took readings with multimeter. Input was open and output was 540 ohms. Replaced input with one that read 540 ohms. Cleared codes and went for a drive. Shifted from 1st to 2nd and when it was about time to shift to 3rd... Kick down into limp mode. Checked codep0733. I read somewhere that the TPS sensor could cause this code. Sounds like a long shot. Any help would be greatly appreciated.

Thanks

 

Well, I changed TPS and no change. Got a donor trans I'm going to swap in a few days.
