Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Ensure the engine is cool before starting any work.

2. Replace Transmission Fluid

Drain Old Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket set and carefully lower the pan to drain the old fluid.
- Clean the pan and inspect for metal shavings or debris.
Replace Filter:
- Remove the old transmission filter and discard it.
- Install the new transmission filter, ensuring it is seated properly.
Install New Fluid:
- Reattach the transmission pan with a new gasket and torque the bolts to manufacturer specifications (typically around 10-15 Nm).
- Using a funnel, refill the transmission with new fluid as specified by the manufacturer (usually T-IV or equivalent).
- Start the engine and allow it to idle to circulate the new fluid, then check the fluid level again and adjust as necessary.

3. Reconnect Battery

Reconnect the battery terminals and ensure they are secure.
