5R55N [99-UP] Automatic Transmission Friction Clutch Pack Clutch Module

When the clutch pack in a 5R55W, 5R55S or 5R55N automatic transmission wears down or glazes over, engagement becomes inconsistent and shift feel deteriorates. This module addresses that directly: it is a single clutch pack unit with all directional grooved friction surfaces, designed to seat evenly and maintain consistent engagement across the full range of operating conditions. The directional groove pattern on every clutch disc allows transmission fluid to move through the pack uniformly during apply and release, which helps prevent the localized heat that shortens clutch life in high-cycle applications.

This is one individual component, not a rebuild kit. It does not include separator plates, an Automatic Transmission Filter, a band, solenoids or any additional hardware. If your job calls for those parts, they need to be sourced separately. The module weighs approximately 3 lb and applies to 5R55W, 5R55S and 5R55N units from 1999 onward.

Before placing your order, locate the transmission identification tag on the unit itself and confirm the code matches one of the three models listed. Year of manufacture alone is not a reliable way to confirm fitment, because the same vehicle platform sometimes carried more than one transmission family across model runs. Cross-reference the unit code, not just the application year.

REMCO has worked in automatic transmission parts since 1991. Each order is picked and verified against its part record before it ships, and the box includes documentation of what is inside.

• Directional grooves on every clutch surface promote even fluid distribution across the pack, reducing heat buildup during engagement cycles.
• This listing is for the clutch pack module only. It does not include steels, bands, Automatic Transmission Filter, solenoids or any other rebuild components. Verify your full parts list before ordering.
• All directional grooved clutch design means the module works regardless of rotation direction, eliminating the fitment guesswork that comes with single-direction friction material.
• Single clutch pack module, approximately 3 lb. Intended for 5R55W, 5R55S and 5R55N automatic transmission units built 1999 and up.
• Before ordering, confirm the exact transmission code on your unit tag matches 5R55W, 5R55S or 5R55N. Do not rely on vehicle year alone to determine compatibility.
