Possible causes of kicks when switching automatic transmissions in Subaru:
Mechanical problems:
* Wear of friction clutches
* Worn or damaged solenoids
* Contaminated or low transmission fluid level
* Torque converter problems
Electrical problems:
* Faulty sensors (speed, selector position)
* Problems with wiring or electrical connectors
* Failure in the transmission control module (TCM)
Software problems:
* Outdated or incorrect TCM software
* Incorrect shift control settings
Other reasons:
* Excessive load on the transmission (towing, off-road)
* Inadequate maintenance (not regularly changing transmission fluid and filter)
* Driving in an aggressive style (sharp acceleration, braking)
How to fix the problem:
1. Check the level and condition of the transmission fluid.
2. Scan the vehicle for transmission-related trouble codes.
3. Conduct diagnostics of solenoids and other automatic transmission components.
4. Consider reprogramming the TCM.
5. If necessary, replace faulty components (for example, clutches, solenoids).
6. Reset TCM adaptive values.
Adviсe:
* Maintain the automatic transmission regularly (change the transmission fluid and filter).
* Avoid aggressive driving.
*If you notice any kicking or slipping when shifting, contact your mechanic immediately.
* Use only high-quality transmission fluid recommended by the manufacturer.
