Transmissions GMC Savanna: How far into a GM transmission should

Customer Question

How far into a GM transmission should the tip of the dipstick extend? Or better yet, where should the HOT hash marks be in relation to the tranny body? I have a 2008 GMC van, 1/2 ton, AWD, that has a 6' dipstick that is twisted from end to end. I think it's too short. I first checked the tranny level in 2010 and found it to be 1.5 qt.s low. After adding to the top of the HOT hash marks, HOT, in park, it has been leaking oil out of the dipstick tube bend/joint near the rear of the engine. (fire hazard) I think it's a ....60-E tranny.
Thanks!

You did NOT answer the question!!! I'm not stupid. I know how to warm up a tranny and use a factory dipstick! But since I added 1.5 qts of oil in 2010 (the first and only time it was adjusted since new), to bring the oil up to the HOT hash marks, on the factory dipstick, it has been blowing oil out the joint halfway up the 6 ft long dipstick tube. Which the shop manual states is the result of overfilling. I believe the factory dipstick was over twisted at the factory and is too short. I specifically asked for the "measurement" inside the transmission where the oil should be when hot and running. So I can check and/or adjust the factory dipstick to be accurate. I believe the tranny IS overfilled because the factory dipstick was made too short, and the leak will stop when the oil level is back to where it should be. Can you or can you not give me that measurement? Is it above or below the gasket line? By how much? Don't tell me I can't adjust the dipstick. As I said, it was twisted at the factory from end to end, all 6 feet of it. I could easily untwist and lengthen the dipstick with the simplest of hand tools.
