The Ford Focus Mk3 2013 2.0 petrol (engine code MGDA) uses a 6-speed PowerShift dual-clutch automatic gearbox (transmission code often referenced as 6DCT450/MPS6).

Here’s the detailed description:

Gearbox Type & Design

• Type: 6-speed wet-clutch dual-clutch transmission (DCT), branded as PowerShift.
• Model Code: 6DCT450 / MPS6.
• Clutch System: Two wet multi-plate clutches – one for odd gears (1, 3, 5, Reverse) and one for even gears (2, 4, 6).
• Operation: Electronically controlled, hydraulically actuated via a mechatronic unit.

Main Features

• Smooth gear changes due to pre-selection of the next gear using the second clutch.
• Wet-clutch design allows better cooling and handling of higher torque compared to dry-clutch systems.
• Adaptive learning for shift timing based on driving style.
• Tiptronic/manual mode available through +/- shifter.

Gear Ratios (Typical for 6DCT450 in MGDA)

1st: 3.77

2nd: 2.04

3rd: 1.32

4th: 0.97

5th: 0.77

6th: 0.62

Reverse: 4.38

Final drive ratio: ~4.23 (varies slightly by market).

Fluid Specification

• Oil Type: Ford WSS-M2C200-D2 specification (Motorcraft Dual Clutch Transmission Fluid XT-11-QDC).
• Capacity: ~6–7 liters total fill.
• Service: Ford recommends fluid change every 60,000 km (in harsh conditions) or 100,000 km in normal use.

Common Notes

• Known for mechatronic unit issues and clutch wear if maintenance is skipped.
• Shuddering on take-off often points to worn clutches or contaminated fluid.
• Correct fluid type and level are critical for smooth shifting and long life.
