Automatic & CVT Transmission Service Gladstone & Calliope
Automatic and CVT transmission servicing, diagnosis and repairs for cars, 4WDs, SUVs, utes and light commercial vehicles.
Total Mobile Mechanical Services supports customers across Gladstone, Calliope and surrounding Central Queensland areas with workshop-based transmission servicing and connected mechanical and electrical diagnosis.
The correct procedure and fluid depend on the transmission fitted to the vehicle. We identify the transmission and assess its condition before recommending service or repair work.
Automatic Transmission Servicing
Transmission servicing requirements vary between manufacturers and transmission designs. Some systems have replaceable filters, removable pans or specific temperature-based fluid-level procedures.
Depending on the vehicle, service work may include:
- Transmission-fluid condition assessment
- Fluid replacement using the specified fluid type
- Transmission-pan removal where applicable
- Filter replacement where serviceable
- Pan and magnet cleaning
- Seal and gasket replacement
- Fluid-level setting using the applicable procedure
- Scan-tool checks and service resets where supported
- Road testing before or after service where appropriate
The recommended service procedure is based on the transmission design, condition, history and available manufacturer information.
CVT Transmission Servicing
Continuously variable transmissions require the correct CVT fluid and service procedure for the transmission fitted to the vehicle.
CVT servicing may include:
- Fluid-condition checks
- CVT fluid replacement
- Filter replacement where applicable
- Pan inspection and cleaning where applicable
- Fault-code and live-data assessment
- Adaptation or relearn procedures where supported and required
Using an unsuitable fluid or treating every CVT as the same design can cause operational problems.
Transmission Fault Diagnosis
Slipping, shuddering, delayed engagement or harsh shifting may be caused by fluid condition, hydraulic control, solenoids, wiring, sensors, control modules, cooling problems or internal wear.
Diagnosis may include:
- Fault-code scanning
- Live transmission-data analysis
- Fluid-level and condition checks
- Electrical circuit testing
- Solenoid and sensor assessment
- Cooling-system inspection
- Road testing under the conditions that produce the fault
- Inspection for leaks, damage or abnormal noise
A transmission fault code is evidence of a detected problem, not automatic proof that the complete transmission must be replaced.
Transmission Repairs
Depending on the diagnosis and transmission design, repairs may include:
- Pan, seal and gasket-leak repairs
- External sensor and wiring repairs
- Solenoid or valve-body work where appropriate
- Transmission-cooler and hose repairs
- Transmission removal and refitting
- Replacement transmission installation where required
The available repair path depends on the transmission, the failed component, parts availability and the condition of the remaining unit.
Transmission Cooling for Towing and 4WD Use
Towing, heavy loads, heat and low-speed off-road operation can increase transmission temperature.
Transmission-cooling work may include:
- Factory cooler and heat-exchanger inspection
- Cooler-hose and line repairs
- Auxiliary cooler installation where suitable
- Cooling-system and airflow checks
- Transmission-temperature monitoring options
Cooling changes must suit the vehicle and transmission. Related 4WD work is available through our 4WD upgrades page.
Transmission Problems That Need Inspection
- Delayed drive or reverse engagement
- Shuddering or vibration
- Slipping or engine-speed flare
- Harsh or irregular shifts
- Transmission warning lights
- Fluid leaks
- Overheating warnings
- Unusual whining, grinding or knocking noises
