This Technical Service Bulletin (TSB 21-026-25) addresses a manufacturing issue in certain 2024 Jeep Wrangler vehicles where the transmission shifter may become inoperative. Owners might see a 'Service Shifter, Stop Safely, Shut Off Engine To Engage Park' message.
Owners of certain 2024 Jeep Wrangler vehicles may encounter an issue where the transmission shifter becomes inoperative. This problem, identified as a manufacturing issue, can prevent the vehicle from being shifted out of Park or its currently selected gear. This concern is addressed by Technical Service Bulletin (TSB) 21-026-25, also released as Rapid Service Update (RSU) 25-041, dated March 20, 2025.
This TSB applies to 2024 (JL) Jeep Wrangler vehicles built on or after September 19, 2024 (MDH 0919XX) and on or before September 30, 2024 (MDH 0930XX).
Symptoms of an Inoperative Shifter
If your 2024 Jeep Wrangler is affected by this issue, you may observe the following symptoms:

The diagnostic process involves attempting to shift the transmission out of Park or its current selected gear. If the automatic shifter is able to shift, the bulletin is considered complete, and an inspection labor operation (21-01-03-94) is used to close the active RSU.
