🔧 What is the 7-speed Powershift transmission?

The 7-speed Powershift is a dual-clutch automatic transmission (DCT) that uses two clutches and two concentric shafts to shift gears quickly and seamlessly. Depending on the version, it can use dry or wet clutches. It offers low fuel consumption and quick gear changes, but requires proper maintenance and careful driving, especially in urban environments.

🚨 Typical symptoms of malfunction

• Jerking when starting or maneuvering at low speed.
• Skidding when accelerating or loss of thrust when overtaking.
• Delays in shifting or hesitations between gears.
• Metallic noises or vibrations when shifting.
• Transmission and limp mode lights .

Warning sign: if the jerking increases while the car is hot or in the tailgate, schedule a diagnosis immediately . Early intervention reduces costs.

🧩 Most common causes

• Clutch wear (especially in the city and with frequent starts): causes jerking and slipping.
• Mechatronics/TCM (Hydraulic-Electronic Control Unit) with defective valves or electronics.
• Actuators/forks and gear position sensors out of tolerance.
• Degraded oil and filter (on “wet” versions): temperatures and wear increase.
• Outdated software : suboptimal gear shift logic and pressures.

🛠️ Solutions and repairs

• Software updates and adaptive clutches → often resolve initial cases.
• Replacing clutch kits and thrust bearings → eliminates persistent tearing/slippage.
• Mechatronics Overhaul/Replacement (TCM) → restores shift precision and pressures.
• Oil and filter service (wet versions) → reduces temperatures and noise.
• Remanufactured unit or complete overhaul → for widespread damage or high mileage.

Partner workshop opinion: "In 40–50% of 'mild' cases, a software update and adaptive reset immediately improve drivability. If the jerking persists, we move on to the clutches or mechatronics."

🧰 Preventive maintenance and guidance

• Oil service on “wet” versions: checks at 40–60,000 km (even if the manual indicates longer intervals).
• Avoid long “creeps” with the brake pedal just released: warm up the clutches.
• When going uphill , use the handbrake/hold and put the vehicle in P when stationary.
• Don't accelerate hard in high gears at low revs: it increases slippage.
• Periodic diagnostics (error log, temperatures, clutch slippage) in the workshop.

💰 Repair costs (2025) with indicative times

Intervention	Description	Approximate cost	Time*
Software update + adaptive	Reset changed logic and pressures	€150–300	1–2 h
Oil service + filter (wet versions)	Recirculation, oil and filter replacement	€150–250	1–2 h
Clutch kit	Clutch pack replacement and adjustments	€800–1,500	1–2 days
Mechatronics/TCM	Overhaul/replacement of hydraulic-electronic module	€900–1,800	1–2 days
Complete overhaul/refurbished	Complete unit with warranty	€2,000–3,000+	2–4 days

*Approximate workshop times: vary by model, diagnosis and spare parts availability.

❓ Frequently Asked Questions

Is it normal to have a little tearing when cold?

A slight roughening may occur when cold; however, if the tugging persists when warm or worsens, a diagnosis is needed.

Can I use additives in my gearbox?

Only if expressly compatible with the manufacturer's specifications. In many cases, the correct oil and regular service are preferable.

How do I extend the life of the Powershift?

Avoid long “creeps”, keep the software updated, service the oil (on wet versions) and adopt a smooth ride at low revs.
