A worn or failed solenoid pack in a 4R100 unit causes shift complaints that no software update or fluid service will fix, and this direct-replacement assembly with the PWM solenoid already included gets the unit back to proper hydraulic control without hunting for an extra component. What sets this part apart from a bare solenoid pack is the integrated PWM solenoid, which is required on 4R100 automatic transmission applications from 1998 and up and is often sold separately elsewhere, adding cost and the risk of a mismatched part.
This is a single-piece solenoid pack assembly, not a rebuild kit. It does not include friction clutch packs, steel plates, an Automatic Transmission Filter, gaskets, sealing rings, or any other overhaul components. If you are doing a full rebuild, you will need those parts under separate listings. This listing covers the solenoid pack with PWM only.
The part number is and it applies to 4R100 units built from 1998 forward. Before placing the order, verify that the code stamped or tagged on the actual transmission case reads 4R100 and that the vehicle model year falls within the supported range. Do not rely on general vehicle year alone, since unit codes and production dates do not always line up exactly with calendar years.
The assembly weighs 4 lb and is packaged with a part record that lists exactly what is inside the box, so receiving inspection takes seconds. REMCO has been working with automatic transmission components since 1991, and every part that leaves the facility is checked against its listing before it ships.
- Replacing a failed solenoid pack restores proper shift timing and helps avoid erratic gear changes that lead to further damage inside the unit.
- This listing is for the solenoid pack assembly only. It does not include any friction discs, steel plates, Automatic Transmission Filter, gaskets, or rebuild kit. Confirm you need this specific part before ordering.
- The solenoid pack ships as a complete new unit with the PWM solenoid integrated, so there is no need to source that component separately or adapt a generic assembly.
- Single solenoid pack assembly with PWM solenoid included. Packaged and verified against its part record before shipping. Weight: 4 lb.
- Before ordering, confirm the transmission code on the unit is 4R100 and that the build date falls within the 1998-and-up range. A mismatch in unit code will result in the wrong fit.
