4L60E 4L65E [82-UP] Automatic Transmission Ring Kit Teflon 2nd Apply Piston

When the outer teflon sealing ring on the 2nd apply piston wears or distorts, apply pressure bleeds past the bore and second gear engagement becomes soft, delayed or inconsistent. This is the replacement outer ring for that specific piston, sized and profiled to restore the hydraulic seal in 4L60E, 4L65E and 4L70E automatic transmission units built from 1982 through 2013.

Teflon sealing rings hold their shape across a wide range of operating temperatures and resist the groove wear that rubber rings can accelerate over time. The outer ring on the 2nd apply piston sits directly against the bore wall during every apply event, so getting that contact surface right matters for consistent shift feel.

This listing is for one ring: the outer sealing ring on the 2nd apply piston. It does not include the inner ring, any other piston rings, clutch packs, steels, or additional seals. If your rebuild calls for more than this position, cross-check your parts list before ordering to make sure each ring is covered separately.

At REMCO, parts like this one are pulled and verified individually against the part record before they go out. There is no pre-packaged bulk here. The item ships with its part identification so you can confirm it matches what you pulled from the unit.

Before placing the order, confirm the transmission code stamped on the unit and the model year, and identify whether you need the outer ring, the inner ring, or both. This part covers the outer position only.

• Restores hydraulic sealing at the 2nd apply piston and helps avoid fluid bypass that causes soft or slipping second-gear engagement in 4L60E, 4L65E and 4L70E units.
• This listing covers the outer sealing ring only. It does not include clutch discs, steels, seals for other pistons, or any additional components. Verify exactly which ring you need before ordering.
• The outer ring is the one exposed to direct piston-bore contact during apply cycles. Replacing it with a properly fitted teflon ring restores the tight bore seal that keeps apply pressure where it belongs.
• Single outer teflon sealing ring for the 2nd apply piston. Covers the 4L60E, 4L65E and 4L70E. Item weight: 1 lb. Picked and checked individually against its part record before it ships.
• Before ordering, confirm the transmission code on the unit, the model year of the vehicle and which ring position needs replacement: this part covers the outer position only, not the inner.
