PDM (TSK) Transmission Sleeve Kit - Subaru / Toyota

PDM Transmission Sleeve Kits (TSK Series)

Our PDM TSK kits are engineered to eliminate a common weak point in many manual transmissions—the soft aluminum bearing extension. Each kit includes a precision CNC-machined stainless steel sleeve, a matching oversized release bearing, specialty grease, installation clip and instructions.

For example, the TSK3 Subaru kit (designed for 6‑speed push‑type transmissions from WRX STI, Forester XT, Legacy Spec‑B, and others) delivers rock-solid durability under aggressive driving, preventing noise, vibration, and premature clutch wear. Similarly, the TSK45 Toyota kit (for R-series transmissions in FJ Cruiser, Tacoma, Hilux, Prado, and Land Cruiser 70 Series) replaces the weak OEM bore with a stainless sleeve—installs in minutes and restores smooth, reliable clutch operation.

Key Benefits:

• 🛡️ Reinforces transmission housing before aluminum wears out

• ⏱️ Easy install—no machining or case modifications needed

• 🔧 Oversized bearing + clip ensures proper engagement and longevity

• ♻️ Fully serviceable—remove or replace sleeve as needed

Whether you're servicing a performance build or maintaining reliability in rugged applications, PDM TSK kits provide a permanent fix for clutch-release-related issues and extend the life of transmission components.
