Automatic gearbox operation diagnosis

 

A correct and precise diagnosis is the first and most important step in repairing any automatic transmission. At Automatico, we don’t guess — we analyze. Our advanced diagnostic service accurately identifies the source of problems, from the smallest pressure leaks to complex mechatronic defects.

 

Thus, you receive an objective assessment of the transmission’s condition, a clear list of faults, and a personalized repair recommendation, with no hidden costs or unnecessary interventions.

Benefits of professional diagnostics

 

Time and cost savings
We avoid unnecessary disassembly and “trial-and-error” part replacements, focusing only on the required repair.

Driving safety
A complete diagnosis ensures that all faults are identified, eliminating the risk of a breakdown on the road.

Total transparency
You receive a detailed report with error codes, measured parameters, and a clear, accessible technical explanation.

The foundation of a successful repair
A correct diagnosis is the basis for any durable and guaranteed repair.

Main Steps of Our Intervention

 

1. Reviewing the history and symptoms
We start with a detailed discussion with the driver to understand the transmission’s behavior under real conditions: at what speeds and temperatures problems occur, what types of noises are heard, and the service history. This information is essential to guide the tests.

2. Advanced electronic diagnostics
We connect our specialized equipment to the transmission and engine interface. We read and interpret all stored error codes and real-time parameters from the control units (TCU), analyzing sensor data, adaptations, and the condition of mechatronic components.

3. Mechanical and hydraulic test on the bench
This is a key stage. The automatic transmission is tested on our specialized test bench. We simulate real operating conditions (load, RPM, gear shifts) to evaluate the behavior of gears, clutches, and the hydraulic system under load, checking pressures, temperatures, and overall performance.

4. Transmission fluid (ATF) analysis
We extract a sample of automatic transmission fluid (ATF). We analyze its color, smell, and especially the presence of metallic particles or deposits. The condition of the ATF tells us a lot about internal wear and the health of the components.

5. Report preparation and technical offer
We provide a complete report with all findings, photos (if applicable), and a clear technical explanation. Based on this report, we offer the optimal recommendation: a simple intervention, partial reconditioning, or a full reconditioning, along with a transparent and detailed price offer. The decision is always yours, with all necessary information on the table.

WARRANTY FOR AUTOMATIC TRANSMISSION REPAIRS

2-year or 100,000km warranty, with the following amendments:

  • The 2 years are cumulated as follows: 1 year standard warranty or 100,000km and 1 additional year if the condition of performing an intermediate inspection 6 months after the internal reconditioning of the transmission is met.
  • The inspection is chargeable.
  • 1-year warranty for the reconditioning of any CVT gearbox model.
  • It is necessary to perform and observe the inspection intervals according to the manufacturer’s requirements (e.g. 60,000km for the VAG range).
  • The car is not overloaded in operation, such as car competitions or taxi activities or driving school.

    FREQUENTLY ASKED QUESTIONS

    Have a question? Here you will find answers to the most frequently asked questions.

    How long does a complete diagnosis take, and what does it cost?

    A thorough and reliable diagnosis typically takes between 1.5 and 3 hours. The duration depends on the symptoms and the complexity of the required tests (electronic, bench testing, etc.). As for the cost, the diagnosis has a fixed fee, which is communicated in advance. This investment is essential, as it ensures that any subsequent repair (if needed) focuses only on the real issues, saving you significant time and money in the long run.

    Why is simply connecting to a scanner not enough for a reliable diagnosis?

    The scanner (electronic diagnostics) is a vital first step, but it is not enough. It indicates where an error occurred, but it doesn’t always tell us why. Many faults (mechanical wear, hydraulic pressure issues) do not generate an error code. That’s why our service combines electronic diagnostics with mechanical and hydraulic testing on the bench. Only by testing the transmission under load and analyzing physical parameters (pressures, temperatures, particles) can we provide a complete and accurate diagnosis—the foundation for a definitive repair.

    What exactly do I receive at the end of the diagnosis? Do I have to commit immediately to having the repair done with you?

    At the end, you receive a detailed technical report that includes error codes, test bench results, fluid analysis, and a clear explanation of the identified issues. Based on this report, our specialists will provide a transparent price offer for the recommended repair. There is no obligation to proceed. You are free to take the report and offer to review your options. We believe transparency and accurate diagnostics are most important, and the decision to work with us is based on trust and professionalism.
