Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission dipstick, funnel, clean rags.
Remove the transmission dipstick and check the fluid level; add fluid if low.
Inspect fluid color and smell; if it’s dark and smells burnt, a fluid change is necessary.

3. Change Transmission Fluid and Filter

Tools Required: Socket set, torque wrench, fluid catch pan, new transmission filter, new transmission fluid (refer to owner’s manual for specifications).
Raise the vehicle using jack stands and secure it.
Place a fluid catch pan under the transmission pan, remove the transmission pan bolts, and carefully lower the pan.
Remove the old filter and install a new one, ensuring it fits securely.
Clean the transmission pan and replace the gasket if necessary.
Reinstall the transmission pan with the correct torque specifications.
Fill the transmission with new fluid through the dipstick tube.

4. Inspect and Adjust Transmission Linkage

Tools Required: Wrench set, pliers.
Locate the transmission linkage, inspecting for damage or misalignment.
Adjust the linkage as necessary to ensure proper engagement between the gear shifter and transmission.

5. Test Transmission Solenoids

Tools Required: Multimeter.
Disconnect the electrical connectors from the solenoids.
Measure resistance across the terminals of each solenoid; compare to manufacturer specifications.
Replace any solenoids that do not meet specifications.
