The Sonnax 44912-08K oversized TCC switch valve kit eliminates bore wear and renews torque converter clutch (TCC) action in Chrysler 45RFE, 545RFE, 65RFE, 66RFE, and 68RFE transmissions. This kit is designed to address common TCC-related issues including trouble codes, TCC slip, no lockup, overheating, loss of fuel economy, improper lockup, and engine stall conditions.

Key Features:

• Lengthened critical spool provides added stability and wear prevention
• Hardcoat anodized aluminum valve combats premature wear
• Oversized design restores proper clearances in worn valve bores
• Includes valve and spring components

Reconditioning the bore and installing this oversized TCC switch valve kit restores crucial clearances for renewed TCC control and operation. This repair solution addresses excess wear in the TCC switch valve bore that allows vital control pressure to escape the circuit, preventing proper torque converter clutch operation.

Note: Installation requires Sonnax tool kit F-44912-TL8 and VB-FIX valve body reaming fixture (sold separately).
