Possible reasons for a strong kick when engaging reverse gear in an automatic transmission:
Mechanical problems:
*Low transmission fluid level
* Contaminated or old transmission fluid
* Wear or malfunction of gears, clutches or other internal components of the automatic transmission
* Malfunction of valve body or solenoids
* Problems with differential or rear axle
Electrical problems:
* Faulty shift lever position sensor
* Problems with wiring or other electrical components that control the automatic transmission
Other reasons:
* Worn or damaged engine or transmission mounts
* Faulty driveshaft (if the car has rear-wheel drive)
* Rear brake problems (due to pads seizing or sticking)
What to do:
1. Check the transmission fluid level: Low fluid levels can cause slippage and shock when shifting gears. Add fluid according to the manufacturer’s instructions.
2. Inspect the transmission: A mechanic can inspect the transmission and check for leaks, wear, or other problems that could cause kicking.
3. Check sensors and electrical components: Check the shift position sensor and other electrical components that control the automatic transmission for problems.
4. Contact a Technician: If you are unable to diagnose the problem yourself, contact a qualified automatic transmission mechanic who can perform further diagnosis and repairs.
