Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Locate the transmission dipstick or fill port.
Remove the dipstick, wipe clean, reinsert, then remove again to check fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.
Inspect fluid condition; if burnt or contaminated, a fluid change may be necessary.

3. Inspect and Replace Fuses

Identify the fuse box location and remove the cover.
Check the transmission fuse for continuity using a multimeter.
If blown, replace with the same amperage fuse.

4. Examine Gear Shift Linkage

Remove the gear shift boot to access the linkage.
Inspect the linkage for any bends, disconnections, or wear.
If damaged, replace the gear shift linkage assembly as necessary.

5. Test and Replace Transmission Control Module (if needed)

Locate the TCM, usually found near the transmission.
Disconnect the electrical connector and perform a visual inspection for damage.
If necessary, replace the TCM following manufacturer instructions and reprogram as needed.
