In the 9G-TRONIC, the individual gears are engaged by three multi-disc clutches and three multi-disc brakes. The purpose of the multi-disc clutches is to transfer the drive torque between two components as a friction connection.

When did Mercedes introduce 9G-Tronic?

The 9G-Tronic was the first rear-wheel-drive 9-speed automatic gearbox with a torque converter, and it made its debut in 2014. In manual mode and S mode in particular, the gearbox responds more spontaneously because of its shortened shift and improved reaction times compared to the old 7-speed.

What is AMG Speedshift TCT 9G?

The inline 6-cylinder engines are coupled with the AMG SPEEDSHIFT TCT 9G (TCT = Torque-Clutch Transmission) transmission. On the one hand, this guarantees maximum comfort during pulling away and shifting, while on the other, it allows for AMG-typical rapid and emotive shifting to suit the selected drive program.

What is 9 speed automatic w OD?

The new 9-speed has a wider gear ratio, including two overdrive gears, and a new clutch design that reduces the overall size of the transmission to fit into current cars equipped with the 6-speed automatic gearbox. A deeper first gear ratio should provide those cars with quicker acceleration, GM engineers say.

Is 9G-Tronic a torque converter?

The 9G-TRONIC automatic transmission from Mercedes-Benz is the world’s first automatic transmission to feature a hydrodynamic torque converter. The transmission transfers torque using a fluid, rather than a mechanical clutch.

Are Mercedes transmissions reliable?

Unlike many other car manufacturers, Mercedes only use automatic transmissions they have built themselves. These are generally very reliable, as long as these transmissions are serviced regularly.

How good is Mercedes 9G Tronic?

The 9G-TRONIC automatic transmission offers smoother shifting for a more comfortable drive. The nine-gear transmission also improves fuel economy dramatically, with a reduction of fuel consumption around 6.5 percent.

Who makes 9G Tronic?

Daimler AG
Mercedes-Benz 9G-Tronic transmission

How does the 9G-Tronic work?

The 9G-TRONIC, an upgrade from the legendary and innovative 7G-TRONIC, utilizes a similar drive program, keeping engine revs low by shifting gears early, offering imperceptible gear changes for the most comfortable ride imaginable. While increasing comfort, the lower revs also reduce the noise level.

What is 8G DCT?

The 8G-DCT has a new, fully-integrated direct control with potted electronics. This uses small magnets to aid faster actuation for shorter response times at reduced weight. The 8G-DCT has dry sump lubrication. A light-weight transmission oil with lower viscosity is used.

Is a 9 speed transmission good?

The nine-speed does a great job hiding its gear count and for the most part doesn’t give much indication it has that many gears. The 6th, 7th, 8th and 9th gears are all overdrive gears, and the top two engage at brisk highway cruising speeds.

What is a Mercedes-Benz 9G-Tronic?

9G-Tronic (codename 725.0) is Mercedes-Benz’s trademark name for its nine-speed automatic transmission. This transmission was introduced in 2013.

What does w9g-tronic stand for?
