Gents, thanks again for all the input, I am grateful.
The lines don't show any visual leaks. I am sliding under the SUV with no lift, so a little limited. I overreacted when I saw the problem, it seemed like a lot of fluid was hitting the ground, and I saw a big open hole. Reflecting, I am thinking the fluid may be leaking and building up inside the shell, and when I stop forward momentum the lost fluid exits the transmission housing.
I discovered this in Smyrna, TN earlier this evening. About five miles after I hooked up a 14 foot trailer. I am now in the first town north of Louisville, KY., which is 201 miles from Smyrna, TN. I added one quart of SuperTech Mercron trans fluid. I had no signs of trans issues before discovering the leak, and after adding one quart of trans fluid and driving 201 miles, noticed no issues. But I surely have a leak.
My hope is I can get to another 343 miles tomorrow by adding fluid as needed. BTW, it is very hard to check fluid on the trans dipstick.
