2021-2023 Jeep/Dodge/RAM D-Clutch Kit Missing Seals

A new manufacturer communication, TSB 21-039-24 REV A, has been issued regarding certain D-Clutch repair kits for 2021-2023 Jeep, Dodge, and RAM vehicles. This bulletin addresses a critical defect where these repair kits are missing essential Carrier Output Shaft Seals. This issue directly impacts the transmission's functionality, specifically preventing the vehicle from engaging reverse gear.

MOPAR is actively working to procure the necessary seals to resolve this problem. Owners and technicians should be aware of this situation to avoid improper repairs and ensure vehicle safety and functionality. This TSB provides crucial guidance on how to handle affected repair kits and what steps to take.

What's the Problem?

The core issue identified in TSB 21-039-24 REV A is that certain D-Clutch repair kits are being supplied with "D-Clutch repair kit missing Carrier Output Shaft Seals." Specifically, the Carrier Output Shaft in these kits is missing two seals. These seals are not currently available for individual purchase, creating a significant challenge for repairs.

Without these seals, rebuilding the transmission will result in a critical malfunction: the "vehicle will not have reverse." This means the transmission will not function correctly, and the vehicle will be unable to back up. MOPAR is working to supply the missing parts, and a solution is expected soon.

Important Warnings for Owners and Technicians

This bulletin includes critical advisories to prevent improper repairs and further issues:

• "Do not rebuild the transmission without these seals otherwise the vehicle will not have reverse." Attempting to complete a transmission rebuild with a defective D-Clutch repair kit will lead to a non-functional reverse gear.
• "Transmission replacement is not recommended as this issue should be solved quickly." Technicians are advised against replacing the entire transmission, as MOPAR anticipates a prompt resolution by supplying correct D-Clutch repair kits.

Repair Procedure Summary

For technicians, the TSB 21-039-24 REV A directs them to refer to STAR Online Publication S2421000001 for detailed instructions on inspecting the D-Clutch repair kit. The procedure involves checking if the Carrier Output Shaft Seals are present on the Output Shaft Carrier Shaft. If the seals are found to be missing, the D-Clutch repair kit should be returned as defective, and a new, complete kit should be ordered.
