So I just did my valve body on my 2014 2500, and I filled the tans back up got it to operating temp and checked the fluid with the truck in neutral and it’s just about to the hot mark.

That’s how the dipstick tells you to check it but I’ve been reading things and they say to check in park.

If I check it in park the fluid is barely on the dipsticks.

Any help would be great.
