Stability, comfort and precision — the foundation of safe driving

Noises from your suspension? Jerking while shifting gears? Car pulling or vibrating? These are clear signs of issues in the transmission or suspension system. At Mario Garage, we perform precise diagnostics and handle all types of faults with expertise and care.

Common symptoms reported by our clients:

- Clunking or knocking when going over bumps

- Vehicle pulls to one side while driving

- Floating sensation, poor handling

- Vibrations during acceleration or braking

- Rattling, grinding or whining while driving

- Jerking, hesitation, or slow gear shifts

- Oil leaks under the car or from the transmission

What we do:

Transmission:

- Automatic, manual and robotic gearbox oil changes (with or without full flush)

- Replacement of clutch, dual-mass flywheel and release bearing

- Programming and adaptation of DSG, EDC, 7G-Tronic, ZF and other gearboxes

- Repair of CV joints, driveshafts, transmission mounts and engine supports

- Replacement of oil seals, bushings, central bearings

Suspension:

- Replacement of shock absorbers, struts, mounts and springs

- Repair/replacement of control arms, ball joints, bushings

- Repair and calibration of air suspension systems

- Full alignment: camber and toe adjustment

Good to know:

- Automatic transmission oil should be changed every 60,000 km. Otherwise → overheating and jerking.

- Clutches wear around 120,000–160,000 km. Always replace with flywheel.

- Air suspension is sensitive to sensors and valve blocks. Requires adaptation after service.

- Bushings and control arms are common sources of steering noise.

Real repairs at Mario Garage:

- BMW 5 Series G30: gearbox jerking — ZF 8HP oil change + adaptation. Smooth shifting restored.

- Mercedes GLC X253: rear knocking — shock absorber and ball joint replaced.

- Audi A4 B9: vibrations while accelerating — CV joint replaced + wheel balancing.

Frequently Asked Questions:

Should I change the transmission oil even if everything works?

Yes. Old oil loses its properties and causes hidden damage.

Do I need an alignment after suspension repairs?

Absolutely. Without it → uneven tire wear, poor handling.

Why does my car feel like it’s floating?

Often caused by worn shocks or rear suspension.

Can you repair mechatronics?

Yes. We program DSG, EDC and more in-house.

Common mistakes made by other garages:

- Replacing clutch without flywheel

- Using generic oil in gearboxes → causes jerking

- No gearbox adaptation after repairs

- Installing cheap shocks → car bounces excessively

- Failing to replace bushings with control arms

Pre-visit checklist:

✔ Any noise while driving?

✔ Jerking when shifting gears?

✔ Last alignment done?
