Stellar Automotive Group 5R55N/W/S Overdrive Servo Cover with 2-Lip Seal Piston – Compatible for Ford & Mercury 1999-Up
Stop harsh 3-4 & 4-5 shifts, delayed band apply, and burnt overdrive bands with this upgraded overdrive servo cover from Stellar Automotive Group.
This direct-replacement servo cover includes the improved 2-lip seal piston design (use with 56528A) for the 5R55N, 5R55W, and 5R55S transmissions. The factory cover and piston commonly warp, crack, or leak under heat and mileage, causing weak apply pressure — leading to slip in higher gears, harsh engagement, and rapid band failure. This precision-machined aluminum cover with bonded 2-lip seal restores firm servo operation, delivers smooth and reliable upshifts, and protects your overdrive band for long-term performance.
Perfect fit for popular models including:
Ford Explorer, Sport Trac, Mustang
Mercury Mountaineer
Lincoln Aviator, LS
Ford Thunderbird
Symptoms of a failing overdrive servo cover/piston:
Harsh or delayed 3-4 or 4-5 upshift
Slipping or no overdrive engagement
Burnt overdrive band on teardown
Servo cover leakage or low pressure
Don't risk another rebuild on a worn servo cover — install the Stellar Automotive Group upgraded cover and piston and shift crisp every time.
