Howdy,
I always wondered why ATF must be checked at a certain temperature range and figure it must expand quite a bit. Old dip stick method had a ~2" of variance. My new Tundra uses the "open valve" method like a differential but needs to be in a specific temperature range that makes it a PITA compared to dip stick although more accurate..
So if I have a 15 qt capacity how much would it measure at 50°F vs 120° F ? As temperature rises does it expand more? Does it even expand or need to be thin enough to fully immerse all the little ports and be flowing fully?
Thanks
