Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid electrical shorts.
Ensure the vehicle is on a level surface and secure it with jack stands if elevated.

2. Check Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add the appropriate type of transmission fluid (consult owner's manual for specifications).
If the fluid is dark or smells burnt, proceed to replace the fluid and filter.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, drain pan, funnel, new transmission filter, new transmission fluid.
Drain the old transmission fluid into a pan by removing the drain plug.
Replace the transmission filter by removing the pan. Clean the pan and install a new gasket.
Reinstall the pan and torque the bolts to manufacturer specifications (usually around 8-12 Nm).
Refill the transmission with new fluid through the dipstick tube as per specifications.

4. Inspect and Replace Sensors

Locate the vehicle speed sensor and transmission output speed sensor.
Disconnect the electrical connectors and remove the sensors using a socket set.
Install new sensors by reversing the removal process. Ensure proper seating and secure connections.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals securely.
Clear any diagnostic codes using the OBD-II scanner.
Take the vehicle for a test drive to ensure proper operation and shifting.
