I am looking for some advice from INGOers who know transmissions. I have a 2006 Jeep Liberty with a 4 speed automatic. It has 91k miles and hasn't been abused but I have pulled a small 4x8 trailer with it occasionally and had it off road on my property in Kentucky a few times but nothing serious like rock climbing or water crossing. Anyway my wife was driving it and it stopped going into 3rd gear. First and second work fine and when it goes to shift into third it's like it goes into neutral. Most of the time it won't throw a check engine code but I do get incorrect 3rd gear ratio occasionally. The transmission fluid is clear and clean and level is ok. I have never had to add any fluid to it and yes, I know how to check it. I have replaced some clutches in my lifetime and replaced a manual transmission once but haven't dealt with automatics much.
So, any ideas? Can third gear just be obliterated with no signs of anything in the fluid? Could it be a shift pack or transmission speed sensor? Any advice would be appreciated.
