Wear at the TCC control valve sleeve and limited contact area at the outer spool bore in Mitsubishi F4A and F5A allows line pressure leakage. This prevents the valve from staying in the applied position, leading to converter apply and release issues, excess slip RPM, TCC cycling and high TCC release pressure. Sonnax TCC control valve kit 41954-03K is a drop-in repair featuring an enhanced design and increased sealing capability to stop line pressure leakage and prevent future wear.
May be used in Mitsubishi front-wheel drive, 96-later valve bodies including F4A41/42/51, F5A51 and Hyundai/Kia A5HF1 and A5GF1. However, OE valve spool diameters MUST be measured to verify application.
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.
Valve repair is needed if with gauge on DR pressure tap damper release pressure does not drop and remain at zero when in full TCC supply.
