Stellar Automotive Group 4F27E/FNR5 OD/Direct/3-4 Clutch Piston fits Ford

Stellar Automotive Group 4F27E/FNR5 Overdrive/Direct/3-4 Clutch Bonded Piston – Compatible for Ford & Mazda 2000-Up

Stop slipping in 3rd-5th gears, delayed upshifts, and burnt overdrive/direct clutches with this precision bonded piston from Stellar Automotive Group.

This direct-replacement piston is the critical apply component for the overdrive/direct/3-4 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 clutch apply — leading to flare on upshifts, slipping under load, and rapid friction failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers crisp 3rd-to-5th transitions, and protects your clutch 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 OD/Direct/3-4 piston:

• Flare or slip on 3-4 or 4-5 upshift
• Delayed engagement in higher gears
• Burnt overdrive/direct frictions on teardown
• Harsh shifts when clutches finally grab

Don’t let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group bonded OD/Direct/3-4 piston and shift strong through every gear.
