Every thime that the 91 th700 changes gear at around 93-100mph it makes a sound a little like a dremmel!
Do I need to be worried?

Does the 91 th700r4 have 4 gears?

I have already posted this but mixt everithing up and posted th400r4.

Anibody frequently driving the th700r4 105mph-up without using additional trans cooler?

Id appreciate any advise or sugestions.
