What is the role of the gearbox?
The gearbox is essential to the operation of a car: without it, nothing moves! It's attached to the engine's drivetrain, and its role is to transform the engine's rotations into the rotation of the vehicle's wheels. The gearbox is used to select the ratios that control engine power.
So, by changing gear and modifying the coordination of the system's gearwheels, another gear is engaged and the gearbox transmits new power to the drive shafts and then to the vehicle's wheels.
What are the special features of Audi S5 gearboxes?
The Audi S5 is usually fitted with a 6-speed manual gearbox: like the Audi S5 4.2 fsi quattro 4×4.
The latest version of the Audi S5 features an 8-speed automatic gearbox. The Audi S5's V8 develops 354 hp at 6,800 rpm, accelerating from 0 to 100 km/h in 5.1 seconds. Fuel consumption is high, however, at 12.4l/100 km, but the choice of automatic gearbox reduces this to 10.8l.
Audi S5: how do I maintain my gearbox?
To prevent gearbox wear and tear, your gearbox needs an oil change every 60,000 kilometers or every 4 years. In fact, a system that lacks gearbox oil is quickly damaged and can lead to high repair costs. Finally, an overhaul is recommended between 15,000 and 30,000 kilometers, or at least every 2 years.
Timing belt replacement is recommended every 90,000 kilometers, and EGR valve replacement every 150,000 kilometers.
When should I repair the gearbox on my Audi S5?
There are several signs that should alert you to a gearbox problem, especially when driving. A cracking sound when shifting gears, or a gear locking up during shifting, is a sure sign! This type of problem is generally due to clutch failure, worn gearwheels or lack of lubrication.
How do I repair the gearbox on my Audi S5?
The first step is to remove the gearbox. In the case of the Audi S5, it should be noted that the engine block is particularly far back and the front wheels are very far forward towards the nose of the car, in order to promote overall mass balance. For this reason, you'll probably need the help of a third party.
For a manual gearbox, you need to pay attention to the following parts:
- Driveshafts must be checked for proper gearing and lubrication;
- The synchronizer ring, whose teeth must remain well shaped and whose wear can be checked with a thickness gauge;
- Bearings and gears, which must be free of corrosion;
- SPI seals, which need to be replaced when worn.
This initial check should enable you to assess whether the gearbox on your Audi S5 needs changing, or whether you just need to buy new parts. If in doubt, don 't hesitate to call in a professional! He'll tell you whether your gearbox is in good condition or needs replacing.
Should I repair my gearbox or replace it completely?
