An essential component of the drive system – a transmission pump (gearbox pump), designed for newer JCB models. It is the heart of the gearbox hydraulics, responsible for generating the oil pressure necessary to control clutches, shift gears, and lubricate and cool the entire system. Precision manufacturing and the use of high-quality materials guarantee that factory pressure and flow parameters are maintained, which is crucial for the smooth and failure-free operation of the Powershift transmission.
By choosing GX-OEM parts, you are choosing the uncompromising quality of the original assembly. Our products are made with the highest precision, guaranteeing a perfect fit and parameters identical to the original. This is the best investment in the long and trouble-free operation of your machine.
| Brand (Machine Type) | Model |
|---|---|
| JCB (Backhoe Loaders) | 2DX, 3CX, 4CX |
| JCB (Telehandlers) | 531-70, 533-105, 535-125, 535-140, 540-170, 550-170, 540-140, 536-60, 535-90 |
The list above is for reference. Before purchasing, we recommend verifying the part number in the parts catalogue for your machine.
Before starting work on the transmission, ensure the engine is off and the machine is secured against rolling. Hot transmission oil can be under residual pressure and can cause severe burns. Use protective gloves and eyewear.
The transmission pump is responsible for the pressure in the entire gearbox. Its wear leads to a drop in pressure, which results in clutch slippage, shifting problems, and oil overheating. A sudden pump failure will immobilize the machine.
A weak pump is a direct path to a burnt-out transmission.
Operating on low pressure causes the clutch packs to slip and burn, which ends in a very expensive overhaul. The cost of a new pump is negligible compared to repairing the entire gearbox. Don't risk the most expensive failure – order a new, OEM-quality pump and restore the correct pressure and smooth operation to your transmission.

The transmission pump operates in a closed circuit and is solely responsible for the operation of the gearbox (changing direction, gears, lubrication). The main hydraulic pump powers the working equipment - the loader and backhoe. These are two separate, independent systems.
2. The gearbox "jerks" when changing direction. Is it the pump's fault?It could be. Jerking is often due to the pressure in the clutch packs building up too slowly. This can be a symptom of a wearing pump, but also of leaks at the solenoid valves, worn seals on the clutch packs, or a clogged filter.
3. Can I operate with a weak transmission pump?It is extremely discouraged. Operating on too low a pressure causes the clutch plates to slip, which leads to them rapidly overheating, burning out, and creating a huge amount of metal filings that contaminate and destroy the entire hydraulic system of the gearbox.
