I drained and refilled my ATF fluid today. But I was unsure how long to warm the engine before I check the level. A guy on You Tube said to start the engine and stop it when the cooling fan turns on, wait 90 seconds, and then check the level. What say you guys about this? One person even said to check it while the engine is running. I put in a little less than 3.5 quarts,drove around the block,stopped the engine and after a minute or two checked the level and I was overfilled. I will recheck it tomorrow. I looked in the manual and found nothing on how to check the level. BTW,I used the Funny Pipe and the fluid fill aperatus from Hopkins as described earlier and it was a breeze. 2017 Pilot EX 6 speed.
