Diagnostics, maintenance and repairs to protect your vehicle's performance

Your engine and transmission are essential to the proper operation of your vehicle. Vibrations, a check engine light, loss of power, hard shifting or fluid leaks may indicate a problem that should be inspected promptly.

At Théo Gosselin, our team provides engine and transmission diagnostics, maintenance and repairs to help identify the cause of the problem and recommend the appropriate service based on your vehicle's actual condition.

Accurate Diagnostics

We assess the vehicle's symptoms and behaviour to help identify the source of an engine or transmission problem more clearly.

Preventive Maintenance

Regular maintenance can help protect key mechanical components, maintain performance and reduce the risk of more extensive repairs.

Clear Recommendations

We explain what we find and the recommended solutions so you can make an informed decision about your vehicle.

When Should Your Engine or Transmission Be Checked?

Some warning signs should not be ignored. A prompt inspection can help identify a problem before it becomes more serious or leaves your vehicle unable to operate.

  • Check engine light
  • Loss of power or acceleration
  • Hard starting

Why Should Engine or Transmission Problems Be Addressed Quickly?

Engine and transmission problems can become more serious over time. Having the vehicle inspected when symptoms first appear may help limit damage and make repairs easier to plan.

Our goal is to determine what should be repaired now, what can be scheduled for later and what simply needs to be monitored. This gives you a clearer understanding of your vehicle's condition.
