1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, transmission fluid pump, funnel, clean rag.
Check the transmission fluid level through the dipstick; add fluid if low.
If the fluid is burnt or contaminated, drain the old fluid:
1. Place a drain pan under the transmission.
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan and allow fluid to drain completely.
Replace the filter if applicable.
Reinstall the transmission pan using a new gasket and torque to manufacturer specifications.

3. Inspect and Adjust Shifter Linkage

Locate the shifter linkage:
1. Inspect for alignment issues or damage.
2. Adjust or replace any misaligned or damaged components.

4. Check and Repair Transmission Control Module (TCM)

Tools Required: OBD-II scanner, multimeter.
If error codes indicate TCM issues:
1. Reconnect the battery and start the vehicle.
2. Use the OBD-II scanner to check TCM functionality.
3. If faulty, replace the TCM according to manufacturer specifications.

5. Final Assembly and Testing

Reassemble any components removed during inspection.
