I didn't take anything personal John, I appreciate any feed back I can get to help solve the problem. I'm not what I would call a tech, I have been doing general repairs on everything from weed eaters to WWII Russian subs, literally since I was old enough to carry tools out of my dads tool box, which he didn't appreciate then. Like I said your comments/suggestions are always welcome, thanks Mark
Ok, might be pump noise. Really bad pump noise. I'm sure the extreme mode maxes out line pressure in attempt to make the clutches hold, so may have overtaxed the pump. I'm pretty sure that it also disables lockup converter functions which will make more heat, especially towing.
With 30 yrs experience as a tech, I'm sure you're correct about where the noise is coming from. I certainly didn't intend to suggest that you didn't. Sometimes noises are hard to pinpoint. I have 26 yrs myself.......and have chased noises a time or two.
