This customer contacted me because their automatic Nissan wasn't changing gears. After a quick investigation I found that the gearbox oil cooler was leaking and the lack of oil was stopping the gearbox from changing gear, we had to carry out the repairs to be able to test the gearbox. Replaced the gearbox oil cooler and pipes then refilled the gearbox with oil and retested. The car drove a lot better after this, but did still occasionally get stuck in a gear. These Nissan gearboxes are prone to internal faults and the lack of oil has unfortunately caused problems. The customer was advised to speak to a gearbox specialist to quote for stripping and repairing the gearbox internals.
