Stellar Automotive Group FNR5 Reduction/OD Brake Clutch Bonded Piston fits Mazda

Stellar Automotive Group FNR5 Reduction/Overdrive Brake Clutch Bonded Piston – Compatible for Mazda & Ford 2006-2012

Stop slipping in 4th & 5th gears, delayed upshifts, and burnt reduction/overdrive brake clutches with this precision bonded piston from Stellar Automotive Group.

This direct-replacement piston is the critical apply component for the reduction/overdrive brake clutch pack in all FNR5 transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens brake apply — leading to flare on upshifts, slipping under load, and rapid clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers crisp 4th & 5th gear performance, and protects your brake clutch pack for reliable daily driving or light towing.

Perfect fit for popular models including:

• Mazda 3, 5, 6
• Mazda Tribute
• Ford Escape, Fusion

Symptoms of a failing reduction/OD brake piston:

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

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