Customer Case Study.
A customer from Wolverhampton contacted A1 Premier Transmissions after noticing increasingly harsh gear changes and a transmission warning light, particularly during slow-moving traffic and longer journeys.
Although the gearbox initially returned to normal once it had cooled, the symptoms gradually became more frequent.
Diagnosing the Fault
Following a comprehensive transmission diagnostic assessment, hydraulic testing and temperature analysis, our technicians identified restricted flow through the transmission oil cooler, preventing the gearbox from maintaining normal operating temperatures.
Our diagnosis identified:
Our Repair Solution
The faulty transmission oil cooler was replaced before the transmission fluid was renewed and the gearbox cooling system thoroughly inspected. The gearbox was then recalibrated where required and extensively road tested to verify stable operating temperatures and smooth gear changes.
Following the repair, transmission temperatures returned to normal, gear changes became consistently smooth and warning lights were eliminated.
The customer returned to everyday driving throughout Wolverhampton with complete confidence in their repaired gearbox.

Automatic gearboxes can overheat due to restricted transmission oil coolers, low transmission fluid, cooling system faults, excessive towing, heavy traffic or internal transmission wear. Specialist diagnostics are required to identify the exact cause.
The transmission oil cooler regulates the temperature of the transmission fluid, helping prevent overheating and protecting internal gearbox components. If the oil cooler becomes restricted or fails, gearbox temperatures can rise rapidly and affect performance.
Yes. Excessive transmission temperatures can cause transmission fluid to break down, reducing lubrication and increasing wear on internal gearbox components. Continuing to drive with an overheating gearbox can lead to more extensive and expensive repairs.
Common symptoms include harsh gear changes, delayed gear engagement, transmission warning lights, overheating, fluid leaks or a burning smell after driving. A professional transmission inspection can confirm whether the oil cooler or another component is at fault.
In many cases, yes. If the problem is caused by the transmission oil cooler, cooling system or another individual component, repairing that fault may restore normal operation without requiring a complete gearbox rebuild.
