Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
Gregg Nader
Constant oscillation of the pressure regulator valve can cause excessive wear at the balance line end of the bore, allowing balance line pressure to exhaust and preventing the pressure regulator valve from stroking to the lower line pressure position. Severe wear prevents line from entering the converter apply circuit, which will also restrict valuable cooler flow. Sonnax pressure regulator sleeve kit 37947-05K mates with the OE anodized aluminum valve or optional Sonnax pressure regulator valve 37947-54. Use of this sleeve allows the valve bore to be oversized, and the hydraulic integrity of the bore to be restored.
