Required tool kit F-94987-TL17 is no longer in production. Check with your distributor for availability.
Vehicles with an Aisin AW 450-43LE transmission may exhibit wear in the secondary regulator valve body bore from continuous movement of the valve, causing loss of hydraulic control. Depending on the area and extent of wear, this can cause an overheated converter or transmission, loss of power and/or planetary and bushing failure. Sonnax oversized secondary regulator valve kit 94987-17K restores hydraulic control of these circuits.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
A vacuum test at the port indicated fails to hold at least 18 in-Hg.
Note: You must remove spring and push the valve to the bottom of the bore to test.
