Tools Required: Socket set, funnel, fluid catch pan.
Sub-steps:
1. Locate the transmission dipstick (if equipped) or access the transmission fill plug.
2. Remove the dipstick or fill plug and check the fluid level.
3. If the fluid is low, add the recommended transmission fluid (consult owner’s manual for specifications).
4. If the fluid is dark, burnt, or contaminated, perform a fluid change:
  - Drain the old transmission fluid into the catch pan.
  - Replace the transmission filter if applicable.
  - Refill the transmission with the correct amount of new fluid through the dipstick tube or fill plug.

3. Inspect and Replace Torque Converter (if necessary)

Tools Required: Transmission jack, socket set, torque wrench.
Sub-steps:
1. Remove the transmission from the vehicle by disconnecting it from the engine and supporting it with a jack.
2. Disconnect the torque converter from the transmission and engine.
3. Inspect the torque converter for any signs of wear or damage.
4. If damaged, replace with a new torque converter, ensuring proper alignment and connection.
5. Reinstall the transmission, ensuring all bolts are torqued to manufacturer specifications.

4. Check Transmission Mounts

Tools Required: Socket set, pry bar.
Sub-steps:
1. Inspect transmission mounts for cracks or excessive wear.
