Aisin Seiki AS66RC and AS69RC units often suffer overheating and converter slip/code issues caused by excess wear in the cooler, main converter pressure and converter relief bores. This wear allows fluid loss, which can lead to poor cooling, low cooler feed, low converter charge, TCC slip and TCC slip codes. When working properly, these valves dampen/absorb pressure spikes to ensure proper apply and release of the TCC.
Reconditioning the bores and installing Sonnax oversized cooler, main converter pressure and converter relief valve kit 122740-10K re-establishes correct clearances for proper valve function.

Steel valves combat premature wear
Annular grooves, where appropriate, help center the valve in the bore to reduce side-load wear
Springs calibrated to match OE function
