Solution

1. Preparation

Gather tools and materials before starting.
Tools required: Transmission fluid dipstick (if applicable), clean cloth, funnel, drain pan, jack and jack stands, gloves.
Safety warning: Ensure the vehicle is on a flat surface and the engine is cool before checking fluid levels.

2. Inspect Fluid Condition

Remove the transmission fluid dipstick (if available) from the transmission.
Wipe the dipstick with a clean cloth and reinsert it fully.
Remove the dipstick again and inspect the fluid:
- Color: Fresh fluid should be bright red. Dark or brown fluid indicates degradation.
- Odor: If the fluid smells burnt, it needs to be replaced.

3. Check Fluid Level

With the engine running and the transmission in park (or neutral), pull out the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
The level should be within the marked range; if low, add the appropriate transmission fluid (consult the owner’s manual for specifications).

4. Change Transmission Fluid (if necessary)

If fluid is discolored, burnt, or the level is low, proceed with a fluid change:
1. Drain Old Fluid:
  - Position a drain pan under the transmission fluid pan.
  - Remove the drain plug or pan bolts and allow the old fluid to completely drain.
2. Replace Filter (if applicable):
  - Remove the transmission pan (if necessary).
  - Replace the transmission filter with a new one.
3. Install Pan and New Fluid:
  - Reinstall the transmission pan (or drain plug) with new gaskets if necessary, torqueing to manufacturer specifications.
  - Using a funnel, pour the new transmission fluid into the dipstick tube until it reaches the full mark.
