Automatic Shifting does not stay long in 3rd gear. What is the cause?
I have a 2006 Jeep Liberty that shifts "improperly." Hard to notice on flat or down hill driving, but up hill driving it is most noticeable. The automatic transmissions shifts from 1st to 2nd appropriately. The shift from 2nd to 3rd feels good, but it does not stay in 3rd gear; the transmission immediately begins to shift into 4th gear, and then eventually 5th. Same thing on downshifting - 4th to 3rd and immediately to 2nd. No TC's. Transmission shop said nothing wrong with transmission. Thank you in advance.
