The secondary pressure regulator valve in Toyota A340E and A340F late units receives regulated line fluid pressure from the main pressure regulator valve, and routes it to the converter and lubrication circuits. The continual oscillation of the steel valve within the aluminum casting creates wear, allowing this valuable fluid pressure to exhaust, resulting in converter complaints, burnt apply components and lube-related failures. Sonnax oversized secondary pressure regulator valve kit 97741-18K restores proper hydraulic clearance in a refurbished bore and includes an O-ringed end plug to positively seal the balance pressure circuit.
