Servo Piston Overdrive 5R55N 5R55S 5R55W 2.915" 56529JA 2000-Up NEW
🇺🇸 Overdrive Servo Piston for 5R55N / 5R55S / 5R55W (2.915") – IND: 56529JA
This is a brand new Overdrive Servo Piston, used in the Overdrive servo apply circuit of the 5R55N, 5R55S, and 5R55W transmissions.
The original servo pistons in these units are known to wear out at the sealing surface, causing pressure loss, which leads to:
• 2nd–5th gear slipping
• Harsh or delayed shifts
• No overdrive engagement
• Transmission flare when accelerating
Replacing this piston is mandatory during rebuild or when correcting OD / shift flare issues.
Size: 2.915" (Check before ordering).
