Stellar Automotive Group 4F27E/FNR5 Reverse Clutch Piston fits Ford 00-Up

Stellar Automotive Group 4F27E/FNR5 Reverse Clutch Piston (1.475" Long) – Compatible for Ford & Mazda 2000-Up

Fix delayed or no reverse, slipping in reverse, and burnt reverse clutches with this precision molded reverse clutch piston from Stellar Automotive Group.

This direct-replacement piston (1.475" length) is the critical apply component for the reverse clutch pack in all 4F27E and FNR5 transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens reverse apply — leading to no reverse, harsh clunks, and rapid clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers instant, firm reverse engagement, and protects your reverse pack for reliable daily driving.

Perfect fit for popular models including:

• Ford Focus, Escape, Fusion, Transit Connect
• Mazda 3, 5, 6, Tribute

Symptoms of a failing reverse piston:

• Delayed or no reverse engagement
• Slipping or weak reverse
• Harsh clunk when reverse grabs
• Burnt reverse frictions on teardown

Don’t let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group bonded reverse piston and get reverse back instantly.
