BMW X5 E53 Automatic Gearbox Jerks When Stopping
Why does the X5 E53 automatic jerk when stopping?
The shift to first gear may happen too late, and the gearbox may have learned bad habits. Resetting the adaptations, an oil change and oil flush, or a software update can help. A software update alone is not necessarily enough.
How are the automatic gearbox adaptations reset?
1. Turn the ignition key to position 2. 2. Press the accelerator to the floor past the kick-down switch for about half a minute. 3. Drive the car, and the gearbox will find the shift points again.
Can an oil leak or a worn gearbox be behind the jerking?
Yes. A leaking electrical connector on the gearbox can cause an oil shortage and jerks; flushing the oils and renewing the connector seal fixed such a fault. If the car kicks forward from speed when braking, the cause can be a completely worn valve body.
What causes a rumble or vibration in D when stationary?
If there is no rumble with the gear selector in neutral, first suspect the engine rubber mount, the driveline supports and the front driveshafts. Play in the front driveshafts is not necessarily felt when the car is standing still.
