In Ford E4OD and 4R100 applications, the OE pump gears often become worn, allowing pressure and volume to drop. This results in problems such as low line pressure, repeat converter failure, pump noise and fault codes related to pressure loss. Sonnax oversized pump gear set 36438AX-01K features precision-machined and matched inner and outer pump gears to restore full pump capacity in affected units. Machining of the pump is required for installation.
