Product Details

The Sonnax 77917-06 is an oversized pressure regulator valve designed to address pressure regulator leakage in GM 4L60, 700R4, and 200-4R transmission pump covers. This precision-engineered valve allows pump covers to be restored to OE specifications by correcting for wear and leakage at the pressure regulator valve bore.

Key Features:

  • Oversized design compensates for worn valve bores in pump covers
  • Restores control over the pressure regulating circuit by eliminating leakage
  • Corrects low line pressure issues during boost conditions
  • Helps eliminate clutch slippage, reverse chatter, and premature clutch failure
  • Requires Sonnax reamer and guide kit 77917-TL or 77917-TLC for proper installation

Applications:

  • GM 700R4 transmissions
  • GM 4L60 transmissions
  • GM 200-4R (TH200-4R) transmissions

This valve is ideal for addressing worn pressure regulator bores that cause low line pressure during boost conditions, often 50-100 psi lower than specification in Reverse. Installation requires boring the pump cover with the appropriate Sonnax tooling to accept the oversized valve diameter.
