Our chief tested this Nissan Qashqai and found the fault was in the gearbox. We did a full gearbox overhaul and fitted a reconditioned valve body. About a month later the gear changes turned very delayed and it would not go into reverse. We opened the gearbox again, replaced a bearing inside and covered it under the warranty at no charge.

The owner brought the Qashqai to us to find out what was wrong, and our chief tested the car. The verdict: the fault was in the gearbox.
We advised a full gearbox overhaul plus a replacement valve body, using a reconditioned part, and quoted both before any work started.
The car is a Nissan Qashqai with an automatic gearbox. It is a popular family SUV in Singapore, the kind of car that does a lot of short trips, school runs and stop-start commuting.
That daily duty is hard on an automatic gearbox. The transmission oil stays hot, the clutches and the valve body inside work constantly, and over the years the internal parts wear. When that wear reaches a certain point, you start to feel it as a jerk on take-off or a gear change that arrives late.
Our chief tested the car and confirmed the fault was in the gearbox. The gearbox needed a full overhaul, and the valve body, the part that directs oil pressure inside an automatic gearbox, needed replacing.
We explained this to the owner and quoted the overhaul and a reconditioned valve body before any work started, so there were no surprises.
Singapore driving is hard on automatic gearboxes. Short trips, constant stop-start traffic and the heat all keep the transmission oil hot. Hot oil breaks down faster, and once it loses its protective quality the internal parts start to wear.
The valve body is full of fine passages and valves that control oil pressure. As the oil ages and tiny wear particles build up, those passages and the bearings inside the box wear too. Pressure drops, gear changes turn slow and jerky, and the wear feeds on itself. By the time you feel a jerk on take-off, the wear is usually well advanced.
Once the owner approved, we did a full gearbox overhaul, not a patch.
About a week after collection, the owner reported a jerk as the car came to a stop and brought it in for us to check. About a month after the overhaul, the gear changes turned very delayed, there was an occasional clunk, and the gearbox would not go into reverse. The owner had the car towed to us. We opened the gearbox again and replaced a bearing inside. The repair was covered by the gearbox warranty at no charge.
The overhaul with the reconditioned valve body came to $3,500 nett, GST included. The overhaul is covered by a 2 year or 40,000km warranty, whichever comes first.
A Nissan Qashqai automatic gearbox overhaul in Singapore depends on what is worn once the box is opened. This job was $3,500 nett for the full overhaul including the reconditioned valve body, GST included. The overhaul carries a 2 year or 40,000km warranty.
What moves the price is how far the wear has spread and whether parts like the valve body need replacing too. A box caught early sits at the lower end. This is why we test the car first and quote before any work begins, rather than replacing everything by default. Diagnosis is free.
Automatic gearbox oil does not last forever, whatever the service booklet implies, especially in Singapore traffic. Changing the transmission oil on time is the single most important thing you can do. Fresh oil keeps the internal parts cool and the valve body passages clear.
The honest part: once the gearbox is already worn and the valve body is faulty, an oil change alone will not fix it. New oil cannot reverse worn parts. At that point a full overhaul is the proper repair. The trick is to act on the early symptoms, a slight jerk or a delayed gear change, before the wear spreads and the repair gets bigger.

A jerk on take-off and a delayed gear change usually point inside the automatic gearbox. Worn internal parts and a faulty valve body drop the oil pressure that makes clean gear changes, so the box hesitates then catches with a lurch. It should be checked.
The valve body is the part inside the automatic gearbox that directs oil pressure to make each gear change. When it wears, gear changes turn slow and jerky. On this Qashqai we fitted a reconditioned valve body as part of the overhaul.
Yes. A full gearbox overhaul carries a 2 year or 40,000km warranty, whichever comes first. About a month after the overhaul, this Qashqai's gear changes turned very delayed and it would not go into reverse, so the owner had it towed in.
