Product Description
AS66RC AS69RC RE6R01A Lockup Boost Valve Kit
Sonnax Part Number: 122740-30K
The lockup boost valve/sleeve assembly in Aisin Seiki AS66RC, AS69RC and RE6R01A transmissions is prone to wear. As the sleeve oscillates from vibrational forces and the valve strokes over time, the wear that occurs prevents proper hydraulic control of the lockup control valve, resulting in a multitude of TCC complaints. Some common symptoms of these side-effects can be TCC slip, TCC slip codes and TCC apply and release concerns. Installing Sonnax drop-in lockup boost valve kit 122740-30K will restore normal TCC operations by re-establishing the proper hydraulic integrity of the Lockup control circuit.
- Sleeve is manufactured from highly wear-resistant aluminum
- Hardcoat anodized aluminum valve combats premature wear
- Drop-in Zip ValveTM parts install quickly and easily

CAUSE
Excess wear of the OE lockup boost sleeve/valve assembly allows main line pressure to cross-leak further down into the bore. This prevents proper hydraulic control of the lockup control valve.
CORRECTION
Restore proper hydraulic control and renew line pressure performance by replacing worn OE parts with a Sonnax drop-in lockup boost valve kit.
