Description   700R4 4-3 Sequence Valve Kit. Corrects no 4th gear problem. Restores hydraulic integrity to the circuit. Tool 77964-RM is also required.   Features A worn 3-4 relay/4-3 sequence valve body bore can cause a no 4th gear situation in a 4L60 or 4L60-E. Due to the constant valve oscillation, wear occurs at the 4th accumulator circuit. This can lower 4th gear pressure by as much as 20-25 psi, resulting in lower servo apply pressure or no 4th gear. Leakage also occurs at the end plug, due to valve hammering. This allows 4th signal oil loss which can result in a no 4th gear situation. Sonnax now offers two oversized 3-4 relay and 4-3 sequence valve kits, 77964-01K for the 4L60 and 77964-04K for the 4L60-E.
