Safety Warnings: Ensure the vehicle is on a flat surface and in "Park" mode before starting work.

2. Address Error Codes

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostics port.
2. Retrieve and record any error codes.
3. Research the codes to identify specific issues related to the transmission or throttle.

3. Transmission Fluid Inspection and Replacement
