Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, funnel, torque wrench
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during work on electrical components.

2. Check and Replace Transmission Fluid

Inspect Fluid Level:
- Locate the transmission dipstick (if applicable).
- Remove the dipstick, wipe it clean, and reinsert it to measure fluid level.
Fluid Change:
- If fluid is low or dirty:
  - Place a fluid catch pan under the transmission pan.
  - Remove the transmission pan bolts and carefully lower the pan.
  - Drain the old fluid completely.
  - Replace the transmission filter if applicable.
  - Clean the pan and magnet inside for debris.
  - Reinstall the pan with new gasket material and torque bolts to manufacturer specifications (usually around 8-10 Nm).
  - Refill with new transmission fluid (check owner's manual for type and amount).

3. Inspect and Replace Transmission Mounts

Visual Inspection:
- Inspect transmission mounts for cracks or separation.
Replacement:
- If damaged, unbolt the old mounts and replace them with new ones.
- Torque the bolts according to manufacturer specifications.

4. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and allow it to reach operating temperature.
Test drive the vehicle to check if the jerking issue has been resolved.
