Sub-steps:
1. Locate the transmission dipstick (if equipped) and remove it.
2. Check the fluid level; if low, prepare to add the correct type of transmission fluid (refer to owner's manual for specifications).
3. If fluid is discolored or has a burnt smell, prepare to replace it:
  - Drain the old fluid using a drain pan.
  - Replace the transmission filter if applicable.
  - Refill with new transmission fluid through the dipstick tube using a funnel, ensuring to use the correct type and amount (typically around 6-8 quarts).
