1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Replace Transmission Fluid

Sub-steps:
- Locate the transmission dipstick and remove it to check fluid level.
- If fluid is low, top up with the manufacturer-recommended ATF (Automatic Transmission Fluid).
- If fluid is dark or smells burnt, drain the old fluid using a fluid pump.
- Replace with fresh ATF, ensuring the correct type and quantity are used.
Tools Required: Fluid pump, funnel.

3. Replace Transmission Filter

Sub-steps:
- Remove the transmission pan (if applicable) by unscrewing the bolts.
- Take out the old filter and replace it with a new one, ensuring proper alignment.
- Clean the pan and magnet (if equipped) to remove debris.
- Reinstall the pan with a new gasket and torque to manufacturer specifications.
Tools Required: Socket set, torque wrench.

4. Inspect Electrical Connections

Sub-steps:
- Check the connector to the transmission for any corrosion or damage.
- Clean or replace any damaged connectors.
- Ensure all relevant sensors (including the throttle position sensor) are functioning and correctly connected.
Tools Required: Multimeter, wire brush.
