Multimeter
Basic hand tools (screwdrivers, sockets, wrenches)
Torque wrench
Transmission fluid (as specified by the manufacturer)
Funnel

Repair Instructions

Step 1: Address any DTCs

If you found DTCs using the OBD-II scanner, research each code to determine the specific issue.
Clear the codes and take a test drive to see if they return. If they do, address the underlying issues.

Step 2: Check and Replace Transmission Fluid

Check Fluid Level and Condition:
- Follow the above instructions to check the fluid level.
- If the fluid is low, top it up with the appropriate type of transmission fluid (check the owner’s manual for specifications).
- If the fluid is dirty or has a burnt smell, a fluid change is required.
Fluid Change Procedure:
- Raise the vehicle securely on jack stands.
- Place a drain pan under the transmission.
- Remove the transmission pan bolts and carefully lower the pan. Allow the fluid to drain completely.
- Clean the pan and replace the filter if equipped.
- Reinstall the pan with a new gasket and torque bolts to manufacturer specifications.
- Refill the transmission with the correct fluid through the dipstick tube.

Step 3: Adjust or Repair Linkage

If the shift linkage is misaligned:
1. Inspect the linkage for any damaged parts.
2. Adjust the linkage as per the service manual specifications.
3. Test the shifter to ensure smooth operation.

Step 4: Inspect and Test the TCM

If the TCM is suspected to be faulty, consider the following:
1. Disconnect the battery.
2. Locate the TCM (usually found near the transmission).
3. Disconnect the TCM harness and inspect for corrosion or damage.
4. Reconnect and test. If faults persist, consider reprogramming or replacing the TCM.

Step 5: Replace or Repair TPS

Testing TPS:
- Disconnect the TPS connector and test with a multimeter for proper voltage readings.
- Replace if out of spec.
Installation:
- Install the new TPS and reconnect the electrical connector.
- Clear any DTCs and check for proper operation.

Step 6: Vacuum Leak Inspection

Inspect all vacuum lines connected to the intake manifold and transmission for cracks or disconnections.
Repair or replace any faulty hoses.

Conclusion

If the issue persists after following these diagnostic and repair steps, it may be prudent to seek professional assistance, as deeper internal transmission issues could be present, requiring specialized tools and expertise. Always refer to the manufacturer's service manual for specific instructions and torque specifications.
