Can't confirm B distance = 1/2 qt. I wouldn't assume it. It probably is quite variable with temp since SM doesn't say; on a cold trans, it says to add until the the dipstick level is below both the A and B hatchmarks. I bet if you were in the A area cold, remeasuring it jsut idling at the correct temp would take you into the B area.4.) I may regret it later, but I decided to add an additional 1/2 qt taking me up to a total of 6.5 qts. You can see that a little goes a long way on the dipstick. A 1/2 qt raised the level about the same distance as the "A" and "B" hash areas on the dipstick. Can anybody confirm that the "B" hash distance on the dipstick is calibrated to equal a 1/2 qt?
Then drive and with the car idling and temp at the specified value, add or remove fluid until it is at the top of the B hatched area.
I've read on other threads that TorquePro will give you trans temp if you add a customized PID .
These modern transmissions seem extremely particularly about fluid levels and measuring them. So it seems it me that I would follow at least that final measuring procedure as per the SM; correct temp, idling. Which means your earlier question of "is fluid going to spray everywhere if I remove the dipstick with the engine" should be a no.
What is the purpose of the "A" hatched area? Maybe the A area is a "cushion" zone so you don't overfill? i.e., don't go into the A area when filling it cold?
BTW, if you used the correct front jacking point using a floor jack like I do, where do you position the second supporting jack?
