When solenoid-related faults bring an automatic transmission into the shop, replacing the full solenoid pack assembly is often the most direct path to restoring normal shift behavior and pressure control. This listing is for a single, new solenoid pack assembly designed for 5R55W, 5R55S, and 5R55N units built from 1999 forward, cataloged internally under the 5R55N model designation.
The assembly ships as one complete unit weighing 5 lb, ready to install without the need to source individual solenoids separately. Because the entire pack is replaced at once, the technician avoids the back-and-forth of testing each solenoid individually, which saves time at the bench and reduces the risk of leaving a marginal solenoid in place that could cause a comeback.
This solenoid pack is the only item included in this listing. There are no gaskets, seals, Automatic Transmission Filter, or other components packaged with it. If your repair also requires sealing components or an Automatic Transmission Filter, those will need to be sourced separately. Reviewing your parts list before ordering will prevent delays on the job.
To confirm fitment, locate the transmission code on the unit itself and match it to 5R55W, 5R55S, or 5R55N. The application covers 1999 and up. REMCO has been working in automatic transmission parts since 1991, and every item is checked against its part record before it ships, so what arrives matches what was ordered.
- Restores correct shift control and pressure regulation, addressing erratic shifts, harsh engagement, or solenoid-related codes that make the transmission unreliable.
- This listing covers the solenoid pack assembly only. No gaskets, seals, Automatic Transmission Filter, or additional components are included. Verify this is the exact part your repair requires before ordering.
- A new solenoid pack replaces the entire assembly as a unit, eliminating the need to test individual solenoids and reducing diagnostic time on the bench or in the vehicle.
- Single solenoid pack assembly, new, weighing 5 lb. Applies to 5R55W, 5R55S, and 5R55N units. Cataloged under model 5R55N for reference purposes.
- Before ordering, confirm the transmission code stamped on your unit matches 5R55W, 5R55S, or 5R55N, and verify the build year falls within the [99-UP] application range.
