A failed solenoid pack in the 5R55W, 5R55S, or 5R55N automatic transmission can trigger erratic shifts, pressure faults, and limp-mode conditions that make the vehicle undrivable, and replacing it with a correctly rebuilt unit is the straightforward fix. This rebuilt solenoid pack carries the 56954L specification and extends retrofit coverage back to 2002, which means technicians working on units from that year onward can use this same part without sourcing a different number.
The part ships as a single component. There are no friction discs, steel plates, sealing rings, Automatic Transmission Filter, or gaskets included in this order. If your repair calls for those items, they need to be sourced separately before the job starts. Confirming the full parts list before the vehicle is torn down saves time and avoids a second trip to the supplier.
This solenoid pack applies to the 5R55W, 5R55S, and 5R55N transmission families in applications from 2004 onward, with the retrofit window covering 2002 units as well. Before placing the order, verify the transmission code stamped on your unit and cross-reference the build date on the core tag. The 5R55 family shares similar housings across variants, and ordering against the wrong suffix creates a return.
The assembled weight is 2.811 lb. REMCO has been working in automatic transmission parts since 1991, and each unit that leaves the facility is checked against its item record before it is packed. The box will include a part description so you can confirm what arrived matches what was ordered. SKU.
- Skip the guesswork on a failed solenoid pack: this rebuilt unit addresses shift faults and pressure control failures that leave the vehicle in limp mode or cause erratic gear changes.
- This listing is a single rebuilt solenoid pack only. It does not include friction discs, steel plates, Automatic Transmission Filter, gaskets, or any other transmission components. Confirm the full scope of your repair before ordering.
- Rebuilt to the 56954L specification with retrofit coverage that reaches back to 2002 units, so one part number covers a wider range of applications within the 5R55W, 5R55S, and 5R55N family without needing a separate order.
- Single rebuilt solenoid pack, SKU, weighing 2.811 lb. No additional hardware is included. What you see in the listing is the complete shipment.
- Before purchasing, verify your unit code matches 5R55W, 5R55S, or 5R55N and confirm the build date of your transmission. Units from 2002 onward may be covered under the 56954L retrofit but cross-check your core tag first.
