The gearbox of the Nissan 350Z is put through its paces like few others in this sports coupé, produced from 2002 to 2009 and sold in excess of 250,000 units. Built for performance and proven in competition by the Nismo arm of the brand, the 350Z uses rear-wheel drive, prioritising driving feel and sharp acceleration.
On the transmission side, the 350Z most commonly comes with a six-speed automatic gearbox — widely fitted on the North American market where the model sold best — or a five-speed manual. In either case, spirited driving demands exemplary maintenance. Our experts share their advice.
Gearbox Oil: Your Performance Ally
A Fluid You Cannot Afford to Overlook
Often forgotten, gearbox oil is nonetheless critical in a sports car like the Nissan 350Z, where the transmission runs hot and works hard. It performs three essential functions:
- detergent properties that keep the internal components clean;
- a thermal role, dissipating the heat generated under sustained driving;
- proper lubrication of every moving part.
Check the oil level and condition regularly. If it has turned very dark, it is saturated with particles and needs changing. If it is below the dipstick marks, this may indicate a leak that should be addressed without delay. As a general guide, the oil should be changed every 60,000 km or every two years on an automatic gearbox, and approximately every five years on a manual.
Carrying Out the Oil Change Yourself
The job is manageable with a basic set of tools. Park the 350Z on a flat, raised surface, place a drain tray beneath the sump, then unscrew the drain plug and allow the oil to flow out. Replace the O-ring if necessary, then refill with oil that meets the specifications in the vehicle's service manual, using a funnel. Check that the level sits between the two marks, run the engine, then drive carefully through all gears — including reverse — before checking for leaks. If in any doubt, a mechanic can take care of it quickly. To understand why a gear lever can become stiff, read why my gearbox is stiff.
Gearbox Failure: Your Options
The Mechanic's Diagnosis
Before any repair work, the source of the problem must be identified. Describe to your mechanic the symptoms you have noticed while driving your 350Z:
- unusual vibrations inside the cabin, particularly in neutral;
- various noises (grinding, clunking, squealing);
- resistance from the clutch pedal or gear lever;
- a burning smell;
- a feeling of sluggishness (harder acceleration, engine revving higher than usual).
The majority of problems can be dealt with at the garage. However, if time or budget is limited, the mechanic may recommend a complete gearbox replacement.
The Reconditioned Exchange Gearbox
You do not have to buy a new gearbox — reliable, but expensive and often with a long lead time. A second-hand unit, on the other hand, can never be tested before fitting. Our reconditioned gearboxes offer the best of both worlds: every unit is stripped down, cleaned part by part, and tested by our experts. The process is also environmentally responsible, as your old gearbox is taken back for recycling. Browse our gearbox catalogue and the Nissan range.
Frequently Asked Questions
The 350Z is rear-wheel drive — does that change how the gearbox should be maintained?
The principles remain the same, but spirited driving puts greater demands on the transmission. Regular oil checks and close attention to any noises or vibrations are therefore especially important.
Can I really do the oil change myself?
Yes, with a few basic tools and oil that meets the manufacturer's specifications. If you would rather leave it to someone else, a mechanic can handle it without any difficulty.
How do I make sure a replacement gearbox is compatible?
Locate the gearbox code on the casing, or provide your number plate so that compatibility can be confirmed before you order.
Where can I find more guides for Nissan sports cars?
See our advice on the Nissan 370Z gearbox or the Nissan GT-R gearbox.
