Electromagnetic coil (solenoid) 477/00824 by GX-AFTER. This is a control element for the drive (transmission) solenoid valve, dedicated to JCB machines. The coil works with valve number 25/104700. It features a distinctive square 2-pin connection socket. It is responsible for controlling oil flow in the transmission system, enabling direction changes or gear shifts.
GX-AFTER electrical components feature high winding precision, guaranteeing the generation of a sufficiently strong magnetic field to move the valve stem, even after the transmission oil has warmed up.
| Machine Group | Types / Models |
|---|---|
| Backhoe Loaders | 1CX, 2CX, 3CX, 4CX |
| Telehandlers | Loadall (various series, e.g., 520, 530, 540) |
| Tractors | Fastrac |
| Others | ROBOT Skid Steers, Rough Terrain Forklifts (RTFL) |
The coil is compatible with the 25/104700 solenoid valve. Before purchasing, check the plug shape (square).
The product is the coil only. If the hydraulic stem is also damaged, the entire solenoid valve (cartridge) must be replaced. When installing, it is worth checking the condition of the electrical plug in the machine's harness.
Transmission coil failure can cause sudden loss of drive or the machine getting stuck in gear. If the coil does not work correctly, the machine may not respond to direction changes (reverse), which poses a collision risk.
Coil 477/00824 converts an electrical signal into mechanical movement in the hydraulic valve.

Coils with this number in JCB machines typically operate on 12V. However, it is always worth checking the marking on the old coil or machine specification.
No, the coil fits a specific type of solenoid valve (25/104700). Transmissions may have different valves depending on the model and year.
No, the offer applies to the coil (electrical component) only. The hydraulic part (valve) must be purchased separately if damaged.
