Transmission Slip Out Of Gear problems of the 2017 Jeep Wrangler

Bought the vehicle new in 2017, and in mid-2018, had a synchronizing arm repaired, as the transmission was slipping out of reverse. In 2019, had it looked at again because it was slipping out of 4th gear, and nothing was found. In late 2020, had it in to check a creaking noise when depressing the clutch (local transmission repair shop), and it was full of rust, they said it needed replaced sometime soon. So we took it in now (Feb. 2021) and they suggested that the transmission needed replaced as well because it slipped out of 4th for them when they drove it. Called the dealership, they recommended calling Chrysler, who opened a case, and now I'm taking it in to have it diagnosed at the dealership and followed up through the case at Chrysler. This seems to be an issue, as I've read several complaints about the same problems and fixes.

Reverse would jump out of gear and grind while driving in gear every time. This required manually holding it down to remain in gear and properly drive in the reverse gear. Fields cjdr in sanford, FL said I would have to agree to pay +$1000 in labor for them to diagnose this if it turned out not to be a valid warranty issue. I declined and accepted living with it. On 12/05/2017, during normal driving suddenly the gearshift could not be put into any gear and the transmission completely failed. My brand new Wrangler with 5000 miles sat at the dealer for service for * days** waiting on two parts: - part: gear-reverse idler 5134496aa - part: synch-reverse 5134498aa fca failed to return the vehicle to me until 03/30/2018. Four months. Not only is that unacceptable, I was treated like garbage throughout the wait by both fca and the dealership service department. I have filed a lemon law claim requesting arbitration with the state of florida attorney general's office and will see a full refund for this ordeal as entitled. Really looking forward to castigating fca at the hearing.
