That's a good idea, but I've really gotten to know the automatic over the last couple of years -- so detecting slippage would be fairly apparent.
The darn TCU/ECU has a mind of its own -- despite meeting (what I think are) all of the requirements for full TC lockup, as documented in the shop manual, it just doesn't want to engage as expected. Especially when first driving on the highway -- it may take several miles before it's "Comfortable" with it.
I think the hill-logic control may have a part in it (it calculates speed, load, and TPS to determine if you're on a hill and to hold a gear or TCLU -- steep ascent or descent). Driving with higher loads and a lower TPS with higher speeds must freak-out the processor. Maybe I need to pull the fuse(s) to reset the processor(s) before trips like this. It happens mostly in cold weather, but sometimes in the summer -- who knows...
