Overview
The ZF 4651.351.057 is a precision-engineered OEM genuine component designed specifically for the WG 110 Series transmission. This part serves as a critical interface within the hydraulic control system, ensuring consistent oil flow regulation and pressure stability during gear shifts. Positioned in the valve body assembly, the 4651.351.057 directly influences shift timing and clutch engagement. As a factory-spec replacement, this SKU restores original performance and extends transmission service life. When paired with a robust TRANSMISSION HOUSING, the entire assembly maintains structural integrity under high torque loads.
Symptoms of Failure
- Delayed or harsh shifting — Worn valve body components cause erratic hydraulic pressure, leading to noticeable lag or jarring gear changes.
- Intermittent gear slipping — A failing 4651.351.057 may allow oil to bypass, resulting in temporary loss of drive power under acceleration.
- Hydraulic fluid seepage — Degraded seals around this part create visible oil leaks near the transmission pan or valve body area.
- Erratic neutral-to-drive engagement — Drivers may experience hesitation or clunking when shifting from park into drive or reverse.

Frequently Asked Questions
Q: Can the 4651.351.057 be reused after removal?
A: No. This OEM part is a wear item that should always be replaced with a new unit during valve body service. Reuse risks internal leakage and shift quality degradation.
Q: What tools are needed for installation?
A: Standard metric socket set, torque wrench (range 8-12 Nm), and a seal pick for O-ring removal. Always replace the O-RING simultaneously.
Q: Does this part fit the ZF WG 180 transmission?
A: Yes, the 4651.351.057 is cross-compatible with WG 180, WG 200, and WG 210 series hydraulic control units, though valve body casting variations should be verified.
