Cause:

Bore wear caused by excessive spring rate and side-loading will result in valve sticking and loss of balance in oil pressure.

Correction:

Sonnax oversized converter regulator valve kit repairs the bore and is an improvement over OE design. The spring and side-load have been reduced and the balance circuit is improved.

Warning:

Reamer kit 96201-TL3 is no longer in production but may be available from distributor inventory.

Replaces both the original 4-spooled converter regulator valve and the original 2-spooled version
Hardcoat anodized aluminum valve combats premature wear
Annular grooves help center the valve in bore to reduce future side-load wear
Two replacement springs are included to compensate for the oversized valve, to reduce the excessive spring force that accelerates bore wear and to work with either the original 2- or 4-spooled OE design
Either 96201-TL3 or F-96201-TL23 can be used to enlarge the bore to accept the oversized valves, for all applications.

Note

Works in 2- or 4-spooled OE applications.
