When solenoid failure takes down shift feel in a 5R55W, 5R55S or 5R55N automatic transmission, replacing the entire solenoid pack as a rebuilt assembly is the direct path back to correct electrical operation. What sets this unit apart is that it covers all three variants of the 5R55 platform in a single rebuilt assembly, rebuilt and inspected before it ships, not a raw used pull handed off as-is.
The solenoid pack controls hydraulic circuit switching through electrical signals. When one or more solenoids inside the pack fail, the transmission responds with delayed engagement, harsh or missed shifts, or sets pressure control and shift solenoid codes. Swapping the full pack removes the need to test each solenoid individually on the bench and rules out intermittent failures that a single-solenoid swap can leave behind.
This listing is for one rebuilt solenoid pack assembly weighing 2.15 lb. It does not include friction clutch packs, steel plates, an Automatic Transmission Filter, gaskets, seals or any other component. If your overhaul requires those parts, they need to be sourced separately. Read the application carefully: the 5R55W, 5R55S and 5R55N share the same transmission family but were installed in different configurations depending on year and drivetrain. Confirm the code cast or stamped on your specific unit before placing the order. Coverage runs from 1999 forward. REMCO has worked in automatic transmissions since 1991, and every unit that leaves here is checked against its own specification before it goes out.
- Restores electrical shift control in 5R55W, 5R55S and 5R55N units, addressing erratic shifting and solenoid-related fault codes that cause drivability failures.
- This listing covers the solenoid pack only. It does not include friction discs, steel plates, Automatic Transmission Filter, gaskets, seals or any other transmission components. Verify what else your repair needs before ordering.
- A rebuilt solenoid pack returns the electrical assembly to working condition as a complete, ready-to-install unit, avoiding the guesswork of testing and replacing individual solenoids one at a time.
- One rebuilt solenoid pack assembly, 2.15 lb. Pulled, inspected and rebuilt to restore proper solenoid function across the 5R55W, 5R55S and 5R55N platform.
- Before ordering, confirm the exact transmission code stamped on the unit, the model year and the engine application. The 5R55W, 5R55S and 5R55N share a platform but are not interchangeable in all applications.
