Overview
The ZF 4657.262.001 STATOR is a critical hydraulic torque converter component engineered specifically for the WG210 series. Positioned between the turbine and pump within the converter assembly, this OEM genuine part redirects fluid flow to multiply engine torque during low-speed operation. The stator, identified by SKU 4657.262.001, utilizes a precision-machined blade geometry to optimize stall ratio and lock-up performance. When integrated with the 4657101042: TRANSMISSION HOUSING, it ensures seamless power transfer through the drivetrain. This genuine ZF component is manufactured to exacting tolerances to maintain hydraulic efficiency across the entire WG200 and WG210 transmission range.
Symptoms of Failure
- Torque converter shudder during acceleration — A worn stator fails to redirect fluid properly, causing vibration between 20-40 mph as the converter struggles to multiply torque.
- Delayed engagement from neutral to drive — Degraded stator vanes reduce hydraulic pressure buildup, resulting in a 2-3 second lag when shifting into gear.
- Overheating transmission fluid — A seized or slipping stator increases fluid turbulence, raising operating temperatures above 240°F and triggering warning lights.
- Intermittent gear slipping under load — When the stator fails to hold its one-way clutch position, the transmission loses torque multiplication on inclines or during towing.

Compatibility
This stator is designed for ZF WG series transmissions, specifically the WG210 and WG200 models. It also fits the WG180 series with minor adapter modifications. The 4657.262.001 stator interfaces directly with the 4657201028: HOUS.FRONT SECT and the 4657201013: HOUSING REAR PART to form the complete torque converter assembly. For secure mounting, use the 0631306792: CYLINDRICAL PIN to align the stator hub with the pump drive. This part is not compatible with ZF Ecomat or AS Tronic series transmissions.
