6F35 Transmission Oil Pump Assembly

The 6F35 Transmission Oil Pump is a replacement front pump assembly designed for selected Ford 6F35 six-speed automatic transmissions. The oil pump is responsible for circulating automatic transmission fluid and generating the hydraulic pressure required for lubrication, clutch operation and valve body control. This product is intended for professional transmission workshops, rebuilders, distributors and wholesale customers repairing worn or damaged 6F35 hydraulic pump systems.

6F35 Transmission Oil Pump Function

The 6F35 Transmission Oil Pump is located at the front section of the automatic transmission and is driven as part of the transmission input system. Ford service information identifies the pump assembly under the basic component number 7A103, positioned behind the torque converter housing and associated with the torque converter hub seal and pump sealing components.

During transmission operation, the pump draws automatic transmission fluid and supplies pressurized fluid to the hydraulic control system. This hydraulic pressure supports clutch application, lubrication of rotating components, torque converter operation and other transmission functions.

A properly operating oil pump is therefore essential to maintaining stable transmission pressure.

Ford 6F35 Oil Pump Applications

The Ford 6F35 is a six-speed automatic transmission used in a range of front-wheel-drive and all-wheel-drive Ford and Lincoln applications. Transmission parts suppliers list applications including selected Ford Escape, Fusion, Edge, Explorer, Taurus, Transit Connect and Lincoln models.

However, the 6F35 was produced in several generations, and the oil pump design was updated during production. A pump should therefore not be selected only by the vehicle model or the 6F35 transmission designation.

The original pump configuration should be inspected before ordering.

Early and Late 6F35 Pump Versions

Correct version identification is one of the most important considerations when ordering a 6F35 Transmission Oil Pump.

Transmission parts catalogues identify an early pump used from approximately 2009 onward where the front seal is retained without a snap ring. A later version introduced around 2013 uses a snap ring to retain the front seal. Some later pump assemblies are catalogued as retrofit replacements for earlier 6F35 units.

Other identifying details can include the number of threaded holes, pump casting configuration and front seal arrangement.

For example, specialist catalogues distinguish a 23-threaded-hole early pump configuration from a later 22-hole pump using a retained front seal.

For this reason, customers should compare the original pump before ordering.

Symptoms of Oil Pump Problems

A worn or damaged transmission oil pump can affect hydraulic pressure throughout the gearbox.

Possible symptoms may include delayed engagement, abnormal shifting, insufficient hydraulic pressure, transmission noise or lubrication-related problems. These symptoms are not exclusive to the pump, so professional diagnosis should be completed before replacement.

Valve body wear, solenoid problems, internal leakage, damaged seals or mechanical clutch components can produce similar transmission behavior.

During rebuilding, technicians should inspect the complete hydraulic system rather than replacing the oil pump without confirming the cause of the problem.

Professional 6F35 Transmission Rebuilding

When rebuilding a 6F35 transmission, technicians should inspect the oil pump together with the torque converter hub, pump bushing, front seal, transmission filter and associated sealing surfaces.

Excessive wear inside the pump body or damaged pump components can reduce hydraulic efficiency. The pump should also be checked for scoring, contamination and abnormal wear caused by metal debris circulating through the transmission fluid.

When transmission contamination is present, related hydraulic passages and cooling circuits should be cleaned according to professional rebuilding procedures before the replacement pump is installed.

Correct assembly and lubrication are important for reliable pump operation after installation.

Compatibility and Ordering Information

Because several 6F35 oil pump configurations exist, customers should confirm the exact pump version before purchasing.

Useful identification information includes:

• Transmission model and generation
• Vehicle production year
• Number of threaded mounting holes
• Front seal retention design
• Pump casting number
• Original pump photographs
• Existing manufacturer or supplier reference numbers

Some transmission suppliers use references such as 46500B and 46500BA to distinguish different 6F35 pump configurations. These are industry or supplier references and should not automatically be treated as Ford OE numbers.

6F35 Transmission Parts Supply

The 6F35 Transmission Oil Pump is suitable for automatic transmission rebuilders, repair workshops and wholesale distributors requiring replacement hydraulic pump components.

Kaisheng Transmission supplies transmission oil pumps, valve body components, friction parts, piston kits, seals, electronic control components and other automatic transmission repair parts for professional customers worldwide.

For wholesale inquiries, customers are encouraged to provide clear photographs of the original 6F35 pump and transmission information. This allows the pump generation and physical configuration to be checked before quotation and shipment, reducing the risk of receiving an incompatible transmission component.
