• Description:

  This Genuine Ford transmission spring fits 20-22 F-250 and F-350 Super Duty trucks with the 10R140 ten-speed automatic transmission and serves as a return spring at a specific clutch hub or drum position. Return springs ensure that the apply piston retracts fully when hydraulic apply pressure is released, restoring clutch pack clearance and preventing drag. A weakened or broken return spring can leave a clutch partially applied, causing tie-up between gears, harsh shifts, or unexpected codes. Each return spring assembly uses a specific spring rate, free length, and seated height matched to the apply pressure target for that clutch. non-OEM springs sometimes use the wrong wire diameter or coil count, altering apply behavior. This Genuine Ford spring is built to factory specification. When servicing the clutch drum, replace the spring assembly any time the unit is opened, set clutch pack clearance to the published specification, and verify clutch apply and release on the bench before reassembling the drum into the case.
