GM 4L80-E/4L85-E Transmission Sonnax Overrun Clutch Valve Kit Fits units 97-later. Insufficient holding power in the overdrive roller clutch is the underlying cause of chronic overdrive roller clutch failure in hardworking 4L80-E and 4L85-E transmissions. When the roller clutch fails, the damage can be catastrophic and the only fix is replacing the drum, planetary assembly and mating components. The Sonnax Smart-Tech overrun clutch valve kit 34200-40K offers a hydraulic solution to this known mechanical problem. With unique rerouting of hydraulic fluid pressure, this patent-pending kit keeps the overrun clutch applied at all times (except OD 4th), reinforcing the roller clutch to adequately support heavy loads. Improves OD roller clutch holding power in D4 and Reverse ranges Extends the life of workhorse transmissions while preventing warranty claims and comebacks Installs quickly onto the valve body — no transmission removal needed Range Gear Overrun Clutch with Sonnax 34200-40K Clutch Valve Kit Overrun Clutch with OE Clutch Valve Park Applied Reverse Applied Neutral Applied Overdrive 1st Applied 2nd Applied 3rd Applied 4th Drive 1st Applied Applied 2nd Applied Applied 3rd Applied Applied D2 1st Applied Applied 2nd Applied Applied D1 1st Applied Applied Note: Any other modifications to the valve body should be completed prior to installing Sonnax Smart-Tech® overrun clutch valve kit.
