Oversized 4-3 Sequence Valve Kit Part No. 77964-04K 3-4 Relay Valve 4-3 Sequence Valve End Plug O-Ring GM 4L60-E, 4L65-E and 4L70-E transmissions often have trouble shifting into or holding fourth gear due to excess wear in the sequence valve bore. This wear allows vital fourth gear accumulator oil to exhaust, resulting in deficient servo apply pressure. Consequences are slipping or no fourth gear operation followed closely by a burnt band. Leaking at the OE end plug also allows oil loss that can leave fourth gear inoperable. Re-establish hydraulic control and restore normal fourth gear operation by reconditioning the bore and installing Sonnax oversized 4-3 sequence valve kit 77964-04K. O-Ringed end plug helps prevent 4th gear oil loss Hardcoat anodized aluminum valves combat premature wear use reamer # 77964-RM2
