Possible reasons for automatic transmission kicking during sudden acceleration:
Malfunctions in the valve body:
* Clogged or dirty solenoids
* Worn or damaged valves
*Low fluid pressure or leaks
Problems with clutches and steel discs:
* Worn or overheated clutches
* Warped or cracked steel wheels
Malfunctions in the electronic control unit (ECU):
* Software glitches
* Breaks or short circuits in the wiring
Other possible reasons:
*Low transmission fluid level
* Contaminated transmission fluid
* Speed sensor malfunctions
*Wiring problems
Troubleshooting:
Eliminating automatic transmission kicks during sudden acceleration requires professional diagnostics and repairs. The following steps may help:
1. Check the level and condition of the transmission fluid: Make sure that the fluid level is correct and that it is not contaminated.
2. Connect a diagnostic scanner: Scan the system for trouble codes that may indicate the cause of the kicking.
3. Check the valve body: Remove and disassemble the valve body to clean and inspect the solenoids and valves. Replace any worn or damaged components.
4. Inspect clutches and steel plates: If necessary, remove and inspect transmission clutches and steel plates. Replace any worn or damaged components.
5. Update ECU Software: If there are software updates available, the ECU may need to be reprogrammed to resolve kicking issues.
6. Check Wiring: Carefully inspect all transmission wiring for opens, shorts or other faults.
Note: Transmission kicking under hard acceleration can be a serious problem that can lead to more serious transmission damage. If you encounter this problem, it is recommended that you contact a qualified mechanic as soon as possible.
