The mark on the dipstick corresponds to the level at temperature listed there. I am not sure why transmissions seem to make more difference than crankcases. It must have to do with the ratio of surface area at the top to the capacity. Normally the oil level is close to the top of the oil pan, its widest part. A little more or less oil is spread over a larger area. I think the fluid level in the transmission is much higher, maybe reaching the point where the round top has less area than lower. 15 quarts of fluid are going to expand more than 5 quarts of oil. More expansion and less area will give more vertical rise.quote:
