Stellar Automotive Group 5R55N/S/W Intermediate Servo Cover (use w/56529K) – Compatible for Ford & Mercury 1999-Up
Fix harsh 2-3 & 3-4 shifts, delayed intermediate band apply, and burnt bands with this upgraded intermediate servo cover from Stellar Automotive Group.
This precision-machined aluminum servo cover is designed for use with the 56529K molded piston and replaces the factory cover that commonly warps, cracks, or leaks under heat and mileage — causing inconsistent band apply pressure, slip in 2nd/3rd gears, and premature band failure. This direct-replacement cover restores firm servo operation, delivers smooth and reliable upshifts, and protects your intermediate band for long-term performance in daily drivers or light towing applications.
Perfect fit for popular models including:
Ford Explorer, Sport Trac, Mustang
Mercury Mountaineer
Lincoln Aviator, LS
Ford Thunderbird
Symptoms of a failing intermediate servo cover:
Harsh or delayed 2-3 or 3-4 upshift
Slipping or no 3rd gear engagement
Burnt intermediate band on teardown
Servo cover leakage or low pressure
Don't risk another rebuild on a worn cover — install the Stellar Automotive Group intermediate servo cover (with 56529K piston) and shift crisp every time.
