Aston Martin DB9 Gearbox

Real sports cars are fitted with manual gearboxes. That’s the view held by driving enthusiasts right across the world – and it is a serious problem for Aston Martin.

Since its launch last year, the firm’s DB9 has come in automatic guise only. And predictably, the system has been criticised by some drivers, who want greater involvement. The good news is that the message has got through to the Ford-owned maker, which has finally added a manual to the line-up. We took control to see if the new box can shift the supercar’s thrills up a gear.

The heart of any Aston is its engine, and the DB9 manual shares the same 6.0-litre V12 unit as its self-shifting brother. With 450bhp and 570Nm of torque fed to the rear wheels, the auto is very fast. However, enthusiasts will be pleased to find that the manual gearbox makes the DB9 even faster.

Slot the short-throw lever into first and unleash the power via the accurate clutch pedal, and the Aston accelerates like a drag racer. The company claims a 0-60mph time of 4.8 seconds, which is 0.1 seconds quicker than the auto.

But more than that, the DB9 offers true supercar performance in any gear. In fact, sticking to the 70mph motorway limit is a challenge.

The DB9 accelerates from 0-100 km/h(62 mph) in 4.9 seconds on a manual gearbox and it will keep accelerating until it reaches its top speed of 300 km/h(186 mph). The DB9 will also produce 80% of the V12 engine’s torque from 1500 rpm. In result, mid-range performance is astonishing, giving instant power almost regardless of engine speed or gear. The DB9 comes with two kinds of gearboxes, a 6 speed manual gearbox with twin-plate clutch and a 6 speed “Touchtronic 2” fully automatic gearbox with dashboard-mounted buttons to select Park, Reverse, Neutral and Drive modes. A flappy paddle gearbox made from magnesium is also optional sited behind the steering wheel.

Buyers who choose the manual do at least get a £3,000 discount over the auto, although at £103,000 this DB9 is not cheap. Yet while your average grand tourer might be better off with an automatic gearbox, we reckon swapping the DB9’s cogs yourself is a wise move but pricing for this small surgery can be costly.

But the real fun doesn’t begin until you get familiar with the magnesium paddle shifters located just ahead of the steering wheel. Like any “auto manual” design, they allow you to easily upshift and down shift the six-speed transmission without removing your hands from the wheel. But unlike any other system tried, this one works with the responsiveness and fluidity of a true manual…even though it has a torque converter instead of a clutch. While you can order your DB9 equipped with a traditional manual transmission, this is the first high-performance car we’d happily take in automatic form. It offers all the seamless gear changes you’d expect when left in “Drive,” but it responds instantly when you tap the paddles and even rev-matches with spot-on accuracy when downshifting. If the Aston Martin folks had told us it was a true sequential manual transmission, we would have believed them.

The difference between a manual and an automatic gearbox

The key difference between a manual and an automatic gearbox is that the manual gearbox locks and unlocks different sets of gears to the output shaft to achieve the various gear ratios, while in an automatic gearbox; the same set of gears produces all of the different gear ratios. The planetary gear set is the device that makes this possible in an automatic gearbox.

We are the gearbox specialists, it’s all we do, and we do it well and we are the best at offering any make or model of gearboxes such as Audi, BMW, Chrysler, Citroen, Fiat, Ford, Honda, Jaguar, Mazda, Mercedes, Mitsubishi, Nissan, Peugeot, Porsche, Renault, Rolls Royce, Rover, Saab, Seat, Skoda, Subaru, Toyota, Vauxhall, Volkswagen, Volvo and much more.

Maintenance

The DB9 Gearbox fluid should be changed periodically. Your owner’s manual should give you the recommended intervals which could be anywhere from 15,000 miles to 100,000 miles. Most DB9 Gearbox experts recommend changing the fluid and filter every 25,000 miles.

Few DB9 Gearboxes have drain plugs to drain the old fluid. In order to get the fluid out, the technician removes the gearbox oil pan. This is quite a messy job and generally not recommended for the casual do-it-yourselfer. Even if the gearbox has a drain plug, the only way to also change the gearbox filter is to remove the pan. When the pan is down, the technician can check for metal shavings and other debris which are indicators of impending gearbox problems.

In most cases during these DB9 Gearboxes services, only about half the oil is able to be removed from the unit. This is because much of the oil is in the torque converter and cooler lines and cannot be drained without major disassembly. The fluid change intervals are based on the fact that some old fluid remains in the system.

When the DB9 Gearbox is serviced, make sure that the correct fluid is used to re-fill it. Each gearbox manufacturer has their own recommendation for the proper fluid to use and the internal components are designed for that specific formula. GM usually uses Dexron, Fords prior to 1983 use Type F while later models use Mercon. Late model Chrysler products use ATF +3 +4 (Not using the correct fluid for Chrysler gearboxes is the most common reason for their gearbox problems.) Toyota sometimes uses Type T which is only available through Toyota and Lexus Parts departments. Honda also specs out their own formula which is available from Honda or Acura parts departments. A gearbox will not work properly or may even slip or shudder with the incorrect fluid, so make sure that you double check. Your owner’s manual will tell you which fluid is required. Naturally, the owner’s manual will try to convince you to only use the manufacturer’s branded fluid, but they will also provide you with the specs for the oil. If the aftermarket product indicates on its container that they meet or exceed the specs for a particular type of gearbox fluid, it is generally ok to use that product.
