727 A727 904 A904 Lube Regulated Pressure Regulator Valve Sonnax Number 22771A-10K. Fits 1962–1977.

Under extreme pressure or temperature conditions, the converter/lube circuit in listed Chrysler RWD units can be restricted by the PR valve. The practice of drilling a hole between passages is problematic. This outdated technique contributes to slow engagements or — if the hole is improperly drilled — excessive converter pressure and low line pressure.

The best way to improve oil flow is to replace the OE valve with Sonnax lube regulator pressure regulator valve 22771A-10K, which ensures oil flow under extreme operating conditions and prevents drainback when the truck is off.

  • Improves converter feed/lube oil flow at critical low RPM and high load conditions
  • Redesigned valve prevents fluid drainback and slow engagements
  • Helps charge the converter in Park
  • Drop-in Zip Valve™ installs quickly and easily

No valve body modifications required.
