Can the AT diagnosis show problems?

[longrunQ]

Or is it just checking that sensors are working?

I was wondering if the onboard diagnosis could tell if you AT lines were clogged, leading the transmission to overheat

No.the way to check for clogged lines and the resulting problems is a line pressure check.
