Product Description
A5GF1 F4A41/42/51 F5A51 R4/V4A51 R5A51 V5A51 TCC Control Valve Kit
REPLACES OE VALVES WITH .405'', .531'' AND .344'' SPOOL DIAMETER. APPLICATION UNITS NOTED MAY LOOK DIFFERENT THAN THE TWO VALVE BODIES PICTURED HERE. 41954-03K SHOULD FIT ALL UNITS WITH MATCHING SPOOL DIAMETERS, EVEN IF LOCATION OF BORE DIFFERS.
Sonnax Part Number: 41954-03K
NO TOOLING REQUIRED
In listed Hyundai/Kia and Mitsubishi units, wear at the TCC control valve sleeve and limited contact area at the outer spool bore 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.
-
- Hardcoat anodized aluminum valve combats premature wear
- Highly wear-resistant alloy aluminum sleeve incorporates an O-ring to provide positive sealing against valuable line pressure leakage to exhaust
- Critical valve spools are lengthened by almost 15%
- More than 80% more sealing contact area at the outboard line port area during TCC apply, while the critical outside diameter of the sleeve provides more than twice as much sealing capacity
- Drop-in Zip Valve™ parts install quickly and easily
PACKAGE CONTAINS

- Sleeve
- O-Ring
SYMPTOMS
- Excess TCC slip
- TCC apply & release concerns
- TCC cycling
- High TCC release pressure
CAUSE
Wear at the TCC control valve sleeve and limited contact area at the outer large spool bore allows line pressure leakage, preventing the valve from staying in the applied position.
CORRECTION
Sonnax drop-in TCC valve kit provides significantly more hydraulic sealing capability with enhanced designs, and prevent future wear with upgraded materials.
