Possible causes of automatic transmission emergency mode in Ford Explorer:
Mechanical problems:
* Wear or damage to internal automatic transmission components (for example, friction discs, planetary gear)
* Faulty torque converter
*Transmission fluid leak
Electrical problems:
* Faulty automatic transmission control solenoid
* Automatic transmission speed sensor
* Gear selector position sensor
*Transmission control module (TCM) problems
Software problems:
*TCM software failure
How to determine the cause:
1. Check the transmission fluid level and condition: Remove the transmission dipstick and check the fluid level. If the level is low or the fluid is dark and smells burnt, it may indicate a leak or internal problem.
2. Scan for trouble codes: Connect the OBD2 scanner to the diagnostic port to check for trouble codes related to the automatic transmission. The codes may indicate a specific faulty component or system.
3. Perform a Transmission Diagnosis: Have a qualified mechanic perform further diagnostics, which may include checking the transmission fluid pressure, checking the solenoids, and inspecting internal components.
Solution:
The solution to the problem of automatic transmission emergency mode depends on its cause. This may include:
* Repair or replacement of internal automatic transmission components
* Replacing the torque converter
* Finding and eliminating transmission fluid leaks
* Replacing a faulty solenoid or sensor
* TCM software update
Important: Do not continue driving in limp mode, as this may cause further damage to the automatic transmission. If your car loses power or is difficult to shift gears, take it to a mechanic as soon as possible.
