Sub-steps:
- Using the funnel, add the new transmission fluid through the dipstick tube or designated fill port until the correct level is reached (check with dipstick).
- Start the engine and let it idle for a few minutes, shifting through all gears to circulate the new fluid.

7. Check Fluid Level

Sub-steps:
- With the engine running, recheck the transmission fluid level using the dipstick.
