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

Owners of 2021-2023 Jeep, Dodge, and RAM vehicles should be aware of a critical issue identified in Technical Service Bulletin (TSB) 21-039-24 REV A, issued on July 17, 2024. This bulletin concerns D Clutch repair kits that may be missing essential Carrier Output Shaft Seals. This defect can impact transmission functionality, specifically the ability to engage reverse gear.

The TSB highlights that some D Clutch repair kits, intended for various Jeep, Dodge, and RAM models, have been delivered to dealerships with two crucial Carrier Output Shaft Seals missing. These seals are not available for individual purchase through MOPAR, complicating repair efforts.

The Issue: Missing Transmission Seals

The core problem described in TSB 21-039-24 REV A is the absence of two Carrier Output Shaft Seals within certain D Clutch repair kits. These seals are vital components for the proper operation of the transmission. If a transmission is rebuilt using a kit that lacks these seals, it will not be able to engage reverse gear.

This issue primarily affects the repair process rather than indicating a widespread manufacturing defect in vehicles already on the road. However, if a repair involving a D Clutch repair kit is performed using a defective kit, the vehicle will exhibit a clear symptom: the inability to go into reverse.

Important Warnings for Owners and Technicians

This bulletin includes crucial advisories to prevent improper repairs and ensure vehicle safety and functionality:

• "Do not rebuild the transmission without these seals otherwise the vehicle will not have reverse."
• "Transmission replacement is not recommended as this issue should be solved with replacement kits."

These warnings emphasize that attempting to rebuild a transmission with an incomplete kit will lead to immediate operational failure. Furthermore, the TSB explicitly states that replacing the entire transmission is an unnecessary and costly measure, as the problem can be resolved by obtaining a complete and correct D Clutch repair kit.

Affected Parts and Kits

The D Clutch Repair Kit is the component identified as potentially missing seals. The specific part numbers associated with this issue include:

• 68239499A$
• 68676887A$
• 68676890A$
• 68676891A$
• 68676892A$
• 68676893A$
• 68676894$

These part numbers are critical for technicians to identify potentially defective kits. MOPAR is actively working to address the availability of these seals.

Repair Recommendation

For technicians, the TSB provides clear instructions. If a D Clutch repair kit is found to be missing the Carrier Output Shaft Seals, it should be returned as defective. A new, complete kit should then be ordered. Technicians are advised to consult STAR Online Publication S2421000001 for detailed instructions on how to inspect for the presence of these seals on the Output Shaft Carrier Shaft.

This process ensures that any repair involving a D Clutch repair kit, such as for a Jeep Wrangler D Clutch repair kit, is performed correctly, restoring full transmission functionality.

What Owners Should Do

If you own a 2021-2023 Jeep, Dodge, or RAM vehicle and are experiencing transmission issues, particularly if a D Clutch repair has recently been performed or is scheduled, it is important to discuss TSB 21-039-24 REV A with your service center. Ensure that your technician is aware of this bulletin and follows the prescribed inspection and replacement procedures for the D Clutch repair kit. This will help prevent issues like the loss of reverse gear.
