One problem related to transmission pump has been reported for the 2014 Jeep Wrangler. The most recently reported issues are listed below.
Approximately 8 months ago, I had my first experience with my jku shifting incorrectly while going up & down the streets which I live on in kailua kona, hawaii. I live on a volcano & thus the streets are at a great degree, up to 25% grade. My first experience with the transmission shifting on its own was coming up a street where I downshifted to 2nd gear. . . . The Jeep then shifted into 1st on its own and then upshifted to 3rd, then down to 2nd & then to 1st, all on its own. I then came to a stop sign & put it back into drive for automatic hoping that it would stop. For about 2-3 weeks after that, it seemed that the transmission slipped every once in a while & then nothing. It drove fine. I never took it to the dealership from that one or two instances. On 8/5/19 I took my Jeep in for a regular oil change. Kona kwik lube looked at everything & said that everything on the jku looked great. I then had to leave town for a week & upon return from the mainland, I had numerous drops (of what I thought was oil) on the floor of my carport. I took my Jeep to repair shop for diagnostic & was told that they saw signs of oil leak from the oil filter housing, but were unable to pinpoint location of leak. As I knew the manager of kkl, I took it back there. They cleaned up the area & stated that it was not oil leak. Upon returning home, I had no leaks coming from the Jeep for 2 weeks. Then the leaks started. I went back to kkl on 10/9/19 where they put dye in the engine to find the leak. On 10/14/19 they saw no dye in the engine, thereby noting that it was transmission. I went to transmission technology right after, & I was advised that I had a german transmission & the transmission pump, seals, etc. Were all leaking & it would be over $2,000 to fix the transmission. I only have 37,933 miles on this 2014 jku. At 37,000 miles, this transmission should not be leaking. Jeep declined cover.
