Product Details
E4OD/4R100 transmissions often have problems with converter overheat, codes 62, 628, 1744, high line pressure and low cooler. The OEM valve can close off critical converter/cooler circuit under high-demand situations, causing the TCC to drag on and glaze the lining at idle, or restricting converter cooler charge during high load causing converter slip codes, overheat and lube failures. flow. Sonnax now offers an upgraded Line-to-Lube Pressure Regulator Valve 36424-04K with a patented internal line-to-lube passage with anti-drain back check valve, and a revised balance-end orifice. While drilling the pump casting will allow full-time flow to the cooler circuit, it is not precise and allows converter drain back, causing delayed engagements complaints. A revised balance end orifice is built into the valve and ensures sufficient oil is fed to the end of the PR valve to keep the valve in the proper regulating position and further preventing converter/ cooler flow restrictions.
