E4OD - 4R100 Line-To-Lube Pressure Regulator Valve Sonnax 36424-04K


Fits Ford E4OD and 4R100 with F1, F5, F8 and E9 stamped pump castings.


This Listing Is For (1) One Sonnax 36424-04K Valve.



Ford E4OD, 4R100 transmissions often have problems with converter overheat, codes 62, 628, 1744, high line pressure and low cooler flow. The OE 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, leading to converter slip codes, overheat and lube failures.

Sonnax drop-in line-to-lube pressure regulator valve 36424-04K corrects these problems with a patented internal line-to-lube passage with anti-drainback 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 drainback, causing delayed engagement 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.

    Valve is hardcoat anodized to reduce wear
    Internal check valve capsule allows full-time flow to the converter/cooler, but prevents drainback
    An added orifice at the balance end ensures sufficient line pressure is present to balance against EPC and spring pressure


Symptoms:

    High line pressure
    Overheated converter
    Code 62, 628, 1744
    Engine stall on engagement in Reverse
    Engine stumble on engagement in Reverse


Cause:

OE valve can restrict converter charge and cooler flow due to wear, and/or insufficient balance oil keeps the PR valve in the high line pressure position.


Correction:

The Sonnax pressure regulator valve kit has a patented internal line-to-lube passage with anti-drainback check valve that allows full-time flow to the cooler circuit, yet prevents dainback.
