Solution

1. Preparation

Gather all required tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands if necessary.
Disconnect the battery to prevent any electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick, if applicable.
Wipe the dipstick clean, reinsert it, and then remove it again to check the fluid level.
If the fluid is low, add the manufacturer-recommended transmission fluid until the proper level is reached.
If the fluid is dirty or burnt, proceed to a fluid change.

3. Replace Transmission Fluid

Drain the old transmission fluid using a drain pan.
Replace the transmission filter (if applicable) by removing the pan (ensure to replace the gasket).
Reinstall the pan and torque the bolts to manufacturer specifications.
Refill with new transmission fluid through the dipstick tube.

4. Inspect and Replace Fuses/Relays

Locate the fuse box and check the fuses related to the transmission.
Replace any blown fuses with the correct amperage.
Test and replace any faulty relays as needed.

5. Repair or Replace Transmission Linkage

Inspect the transmission linkage for wear or disconnection.
If damaged, replace the linkage components.
Ensure proper adjustment of the linkage after replacement.

6. Test Transmission Solenoids

Disconnect the electrical connectors from the transmission solenoids.
Use a multimeter to test for proper resistance according to the service manual specifications.
Replace any faulty solenoids with new components.
