5R55W [02-UP] Automatic Transmission Bushing Overdrive Servo Bore Pin

When the overdrive servo bore pin seat in a 5R55W, 5R55S, or 5R55N unit has worn beyond acceptable limits, replacing the full servo housing is not always the only path forward. This sleeve goes directly into the bore, restoring the seating surface so the pin can hold pressure and move as it should, which matters for overdrive engagement and overall shift behavior in these units.

This is a single piece, not a kit: one overdrive servo bore pin repair sleeve sized for the 5R55W, 5R55S, and 5R55N automatic transmission family, covering applications from 2000 onward. The listing does not include seals, pistons, springs, servo covers, or any surrounding hardware. A technician working this repair will need to source those items separately if they are also needed.

The sleeve weighs approximately 1 lb. REMCO has been working in automatic transmission parts since 1991, and each order is assembled and checked against its part record before it ships. A part list is included in the box.

Before purchasing, locate the transmission identification code stamped on your unit and confirm it reads 5R55W, 5R55S, or 5R55N. Also verify the bore condition and the pin diameter against your service specifications, because the sleeve must fit correctly to restore proper function. If the bore damage is beyond what a sleeve can address, this piece will not resolve the problem. Confirm all measurements first.

• Addresses worn or damaged overdrive servo bore pin seats in 5R55W, 5R55S, and 5R55N automatic transmission units, restoring proper servo function and stopping pressure loss at that bore.
• This listing is a single repair sleeve only. It does not include a servo assembly, seals, pistons, springs, or any other components. Verify your exact need before ordering to avoid a return.
• A bore pin repair sleeve corrects the bore itself rather than replacing the entire servo assembly, targeting the worn surface directly so the pin seals and travels as originally designed.
• One overdrive servo bore pin repair sleeve. Item weight: 1 lb. Piece count is one unit; confirm quantity needed for your job before purchasing.
• Before ordering, match the transmission code on your unit: this sleeve fits 5R55W, 5R55S, and 5R55N. Confirm the code, build year, and bore condition with your own measurements first.
