PDM Transmission Sleeve Kit (TSK)

Our TSK Kits include everything you need for a superior clutch repair: an oversized clutch release bearing, a stainless steel sleeve, special high-temperature grease, and detailed instructions for easy installation. Important Note: Failure to use the included clip will void the warranty.

Common Symptoms Addressed by the TSK Kit:

• Clutch chatter
• Excessive noise
• Sticky or stiff pedal
• Rough pedal travel
• Premature wear or failure of clutch components

Traditionally, the only solution for these issues was to replace the damaged or worn transmission case. However, this approach merely restarts the cycle, as the throw-out bearing continues to wear down the new aluminum surface.

The PDM TSK Difference: The PDM Transmission Sleeve Kit (TSK) offers a permanent, more effective solution by directly addressing the root cause—the soft aluminum surface of the transmission case extension. The TSK provides a durable, long-lasting stainless steel sleeve for the throw-out bearing to ride on, eliminating the issue once and for all.

Key Benefits of the PDM TSK:

• Prevents further damage by replacing the weak aluminum surface with a robust stainless steel sleeve.
• Offers a lasting solution that doesn’t just mask the symptoms but cures the problem at its source.
• Simple installation: the PDM TSK can be installed in under 5 minutes, without any modifications to the transmission case.
• Fully removable for future repairs as needed.

By using the PDM TSK, you’re not only ensuring a smooth, noise-free clutch operation but also extending the life of your transmission components.
