Thanks Mark. I wasn't aware of that. I have also read it could possibly be the fan clutch.?. Is there any way of diagnosing before diving in? There is a shop close by with an AE scanner. Would that tell me? Also, is the TRS easy to get to after dropping the pan? I know my way around the 6.0 a little bit with the usual hpop, oil cooler and egr problems but have never tackled anything with the tranny. I really appreciate your expertise and advice!

There are diagnostics in the shop manual. I don't have a manual to share that with you.

The TRS is not hard to change once the pan is off.
