- VB-FIX
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 oversized line-to-lube pressure regulator valve kit 36424-16K corrects these problems with a patented internal line-to-lube passage with antidrainback check valve and a revised balance-end orifice.
- Hardcoat anodized aluminum valve combats premature 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
- Carbide reamer in tool kit allows bore to be resized despite hardness of pump body material
