Automatic transmission diagnostics can show the following parameters:
Current settings:
*Current transmission mode (P, R, N, D, S, L)
*Transmission fluid temperature
* Transmission fluid pressure
* Rotation speed of input and output shafts
* Clutch slippage
* Torque converter lock
Stored fault codes:
* Codes indicating problems or malfunctions in the automatic transmission
* Information about when and under what conditions the malfunction occurred
History data:
* History of fault codes previously stored in the automatic transmission memory
* Automatic transmission operating parameters at the time of malfunction
Tests and checks:
* Gear shift tests: check for proper gear shifting in various modes
*Torque Converter Lockup Tests: Checks torque converter operation and fluid coupling lockup
* Transmission fluid pressure tests: checking pressure under various automatic transmission operating conditions
Adaptive values:
* Parameters that the automatic transmission adapts to driving style and operating conditions
* For example, gear shift points, shift pattern, clutch pressure
Other options:
* Transmission fluid level
*Transmission fluid quality
* Information about automatic transmission firmware
These parameters allow automatic transmission diagnostics to identify faults, assess the condition of the gearbox and make a decision on the necessary repairs or maintenance.
