6T30 6T40 Gen 2 6T45 Gen 2 6T50 Gen 2 O-Ringed End Plug Kit

  • 6 End Plugs
  • 9 O-Rings (3 extra)

Description: OE end plugs are designed to capture the valve train in the bore, retain critical oil pressure and function as a spring or valve stop. Repetitive spring movement, valve impacts and abrupt fluid pressure variations promote wear of the end plug circumference and bore ID surface, eventually allowing vital oil pressure to escape the circuit.

GM 6T30 and second generation 6T40, 6T45 and 6T50 valve bodies have end plugs at the various clutch regulator valve bores that are susceptible to the wear conditions described above. When actuator/solenoid feed pressure leaks out of the affected circuit, various shift concerns and burnt clutches will result. A worn TCC regulator end plug or clutch select valve end plug allows critical oil pressure loss leading to drivability complaints. Reduce or eliminate leakage and restore hydraulic integrity by installing this end plug kit.

Renews hydraulic control and restores critical circuit pressures by installing the this Sonnax kit.
