Product Function

The 2nd-apply servo operates the internal 2-4 band. A Corvette-style servo uses a larger apply-piston design than many stock configurations, supporting stronger band application and a more positive shift feel in properly built compatible transmissions. Comparable Corvette servo kits are commonly sold with the piston, housing/cover, O-rings, and scarf-cut or Teflon sealing rings for this purpose.ebay+2

Service Benefits

Replace servo pistons, O-rings, and Teflon sealing rings when servicing a worn or leaking servo assembly. Damaged seals and worn components can contribute to delayed or soft shifts, shift flare, loss of consistent band apply, or other 2nd- and 4th-gear driveability concerns.
