AODE Transmission

Main Pressure Regulator Valve
Part No. 76948-01

Replaces '95-Earlier 4-spool valves only. DOES NOT replace 3-spool valves.

Vehicles with 4R70W and AODE transmissions often have erratic line pressure, poor line rise and/or throttle-sensitive buzz. This can result in harsh or soft shifts and band/clutch failure as well as other driveability concerns. Worn pressure regulator valve spools allowing pressure escape are a common problem in these units. Installing Sonnax main pressure regulator valve 76948-01 restores normal line pressure operation in all ranges.

If bore is excessively worn, install Sonnax oversized pressure regulator and boost valve kit 76948-16K.

  • Hardcoat anodized aluminum valve combats premature wear
  • Annular grooves help center valve in bore to reduce side-loading

'91–'95 PR valve and '96-later PR valve designs are not interchangeable. For '96-later PR valve, see 76948-09.

Symptoms:

  • Poor shift quality
  • Soft shifts
  • Low line rise
  • Erratic buzz
  • Premature clutch failure
  • Premature band failure
  • Uncontrolled pressure in Reverse
  • Low Reverse boost

Cause:

Regulator valve wear allows critical fluid loss that results in driveability concerns.

Correction:

Renew pressure regulator performance and revive line pressure control by installing Sonnax main pressure regulator valve.
