Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Locate the Transmission Dipstick: Open the hood and locate the transmission dipstick.
Check Fluid Level: Remove the dipstick and clean it with a cloth. Reinsert and remove again to check the fluid level.
Add Fluid if Necessary: If low, add the manufacturer's recommended transmission fluid through the dipstick tube.
Inspect Fluid Condition: If the fluid appears dark or burnt, a complete fluid change is necessary.
Drain Old Fluid: Place a drain pan under the transmission pan and remove the drain plug (if equipped) or the pan itself to drain the old fluid.
Replace Fluid Filter: If applicable, replace the transmission filter while the pan is off.

3. Inspect Transmission Components

Inspect Solenoids: Disconnect the wiring harness and remove the transmission pan. Test each solenoid with a multimeter according to manufacturer specifications.
Replace Faulty Solenoids: If any solenoids fail the test, replace them with new parts.
Check Linkage/Cables: Inspect the transmission linkage or cables for any signs of damage or misalignment. Adjust or replace as necessary.

4. Reassemble and Test

Reattach Transmission Pan: Clean the pan gasket surface and apply new gasket or RTV sealant if required. Torque the pan bolts to the manufacturer's specifications.
Refill Transmission Fluid: Using a funnel, refill the transmission with the appropriate fluid until the correct level is reached.
Reconnect Battery: Reconnect the negative battery terminal.
Test Drive: Start the vehicle and test drive to ensure proper shifting and behavior.
