How do you deal with gearbox failure?
Understanding the constitution of a transmission
The transmission system extends from the gearshift to the wheels. The gearbox consists of the following components:
- The sliding gear locks the gear ratio by attaching one of the idler gears to the shaft it occupies;
- The selector forks move the shifter to engage the gear by locking one of the pinions on the secondary shaft;
- Synchronizers enable smooth gear locking;
- Theinput shaft, connected to the crankshaft via the clutch, rotates at the same speed as the engine;
- Thesecondary shaft contains the pinions for each gear;
- Theintermediate shaft links the primary and secondary shafts;
- The differential distributes speeds to the left and right wheels;
- Bearings are used to rotate drive shafts.
Parts external to the gearbox include the linkage, universal joints, clutch and flywheel.
Know the specifics of the Mercedes E-Class gearbox
Depending on the version, transmission is either rear-wheel drive or all-wheel drive.
Whatever the type of engine chosen - petrol, diesel or hybrid - the gearbox can be manual or automatic. On the first two generations, it features four or five gears on the W124 phase 3 and the W210.
Both the 200 D EXECUTIVE 9G-TRONIC and the 200 FASCINATION 4MATIC 9G-TRONIC feature a 9-speed G-Tronic automatic gearbox with hydraulic torque converter and electronic control.
The mechanical gearbox is available with up to six speeds, and offers 180 hp on the 200 FASCINATION.
