Stellar Automotive Group CD4E 2-4 Servo Piston (No Ring) fits Ford 94-09

Stellar Automotive Group CD4E 2-4 Servo Piston (No Ring) – Compatible for Ford 1994-2009

Fix harsh 2-3 & 3-4 shifts, delayed band apply, and burnt 2-4 bands with this upgraded molded 2-4 servo piston from Stellar Automotive Group.

This direct-replacement piston (no-ring design) is engineered for the 2-4 servo in all CD4E transmissions. The factory piston commonly cracks or loses seal integrity under heat and mileage, causing weak or inconsistent band apply — leading to banging shifts, slip, and rapid band failure. This molded piston with permanently bonded rubber seal restores firm, reliable servo operation, delivers smooth 2-3/3-4 transitions, and protects your 2-4 band for dependable daily driving.

Perfect fit for popular models including:

• Ford Focus, Contour, Escort, ZX2
• Mercury Cougar

Symptoms of a failing 2-4 servo piston:

• Harsh bang or flare on 2-3/3-4 upshift
• Delayed then hard 3rd/4th engagement
• Burnt 2-4 band on teardown
• Low servo pressure during testing

Don’t let a cracked piston cost you a band — install the Stellar Automotive Group no-ring 2-4 servo piston and shift smooth again.
