Inspect Fluid Level:
- Remove the transmission dipstick and wipe it clean.
- Reinsert the dipstick fully and remove it again to check the fluid level.
Add Transmission Fluid:
- If low, use a funnel to add the recommended type of transmission fluid (refer to owner's manual).

3. Inspect and Repair Transmission Linkage

Visual Inspection:
- Locate the transmission linkage and visually inspect for any damage or misalignment.
Adjustment:
- If necessary, adjust the linkage according to manufacturer specifications.
Replace Worn Components:
- If any components are damaged, remove them using the appropriate socket and replace with new parts.

4. Scan for Error Codes

Connect OBD-II Scanner:
- Plug in the OBD-II scanner to the diagnostic port and retrieve error codes.
Analyze Codes:
- Identify any codes related to the transmission and address any specific issues indicated.

5. Test Drive

After repairs are made, take the vehicle for a test drive to ensure that the transmission engages smoothly and does not slip.
