Customer Case Study.
A driver from Maidstone contacted A1 Premier Transmissions after their automatic vehicle began changing gear harshly when slowing down and occasionally displaying a transmission warning light.
The fault was intermittent at first but became more noticeable in stop-start traffic and during journeys around Maidstone. The customer arranged a specialist assessment before the gearbox suffered further internal damage.
Diagnosing the Fault
Our technicians carried out an electronic transmission scan, hydraulic-pressure testing and a detailed assessment of the automatic gearbox.
The investigation identified a failing pressure-control solenoid within the valve body, preventing the transmission from regulating hydraulic pressure consistently.
Our diagnosis identified:
Our Repair Solution
The affected valve-body solenoid was replaced and the hydraulic-control system inspected for contamination or related wear.
Our technicians then renewed the appropriate transmission fluid, completed the required gearbox adaptations and tested the vehicle under a range of driving conditions to confirm consistent operation.
Following the repair and recalibration, the harsh downshifts were eliminated and the automatic gearbox returned to smooth, predictable operation.
The warning light did not return during testing, allowing the customer to resume everyday journeys throughout Maidstone with renewed confidence in the vehicle.
If your vehicle is changing gear harshly, hesitating, displaying warning lights or behaving differently once warm, our transmission specialists are here to help.

Harsh downshifts can be caused by valve-body wear, faulty pressure-control solenoids, hydraulic-pressure problems, contaminated transmission fluid or electronic control faults. A specialist diagnostic assessment is needed to identify the exact cause.
A pressure-control solenoid regulates hydraulic pressure inside many automatic gearboxes. If it becomes worn or fails, the transmission may shift harshly, hesitate, slip or display warning lights.
In many cases, yes. Depending on the gearbox and the extent of the fault, an individual solenoid or the valve-body assembly may be repaired or replaced without rebuilding the entire transmission.
Some gearbox faults become more noticeable once the transmission reaches operating temperature. Heat can expose worn seals, hydraulic-pressure loss, solenoid faults or valve-body wear that may be less obvious when the gearbox is cold.
Yes. A warning light that appears and then disappears can still indicate an electronic, hydraulic or mechanical transmission problem. Stored fault codes may remain in the vehicle’s control system even when the light is no longer visible.
Yes. Our technicians repair automatic, manual, DSG, CVT, DCT and Powershift transmissions across a wide range of vehicle manufacturers using specialist diagnostic equipment and established repair procedures.
