Diagnostic Checks for Automatic Gearbox Repairs in Croydon

 

 

If you are experiencing problems with your automatic gearbox, such as poor response times or rattling sounds, the technicians at Wavertree Automatics are trained to resolve faults with modern automatic gearbox repairs in the Croydon area. We use cutting-edge diagnostic equipment to undertake fault-finding techniques for your DSG gearbox and other traditional automatic gearbox systems.

 

To identify the root cause, and to fix, replace or recondition defective components, we examine the Transmission Control Module (TCM) and Engine Control Unit (ECU) for accurate readouts. Whatever the issue may be, motorists in Croydon and the wider London, Surrey and Kent areas can rely our expertise as a leading automatic gearbox specialist.

State-of-the-Art Diagnostic Equipment

 

 

Before we undertake automatic gearbox repairs, we connect to the Engine Control Unit (ECU) and Transmission Control Module (TCM) to check the condition of the automatic transmission system from the stored data. State-of-the-art diagnostic equipment allows us to patch into traditional and DSG gearboxes to assess where issues lie. Any slight electronic fault will be recorded, including out-of-the-ordinary activity detected from defective hydraulic or mechanical components.

 

This modern approach to automatic gearbox repairs has revolutionised how technicians perform fixes, restorations and reconditioning techniques, which are extremely complex in design. Because of the precise and efficient way in which automatic transmission and DSG gearboxes can be repaired, there is greater demand for automatic gearbox specialists in Croydon and throughout London, Surrey and Kent too.

 

It is important that automatic gearbox repairs, including fixes for a DSG gearbox, are conducted by a professional who is trained to interpret stored fault codes and to carry out the correct course of action.

Maintaining an Automatic Transmission Control Unit (TCU)

 

 

It is equally important for Croydon motorists to monitor the condition of their automatic Transmission Control Module (TCM) and to get in touch with an automatic gearbox specialist as soon as there are signs of a problem. This is because the TCM effectively calculates multiple inputs received from the Engine Control Unit (ECU) and other sensors, then converts those inputs into outputs which power automatic transmission components.

 

Common input parameters received and calculated by a TCM include the following:

 

  • Cruise Control Systems
  • Brake Light Switches
  • Fluid Pressure Sensors
  • Kick-Down Switches
  • Throttle Position Sensors (TPS)
  • Transmission Fluid Temperature (TFT) Sensors
  • Vehicle and Wheel Speed Sensors (VSS/WSS)

 

An automatic gearbox electronically controls the valve body through electrical solenoids. These Pulse Width Modulation (PWM) linear solenoids need to be calibrated to keep the automatic transmission system running smoothly. Modern diagnostic equipment allows us to maintain the smooth functioning of a DSG gearbox and all other automatic gearbox models for our valued Croydon customers.

 

If your automatic transmission encounters a failure, it can cause long-term damage if not resolved quickly, so don’t risk things escalating to a roadside breakdown. Most TCMs in need of automatic gearbox repairs will provide fault codes, which an automatic gearbox specialist can read. Once connected, we can check these fault codes to fully understand the issue.

 

This can often be a sensor or component malfunction between the input and output process.
