I got 230+k out of one, 240+k out of another 4r100, both in trucks that pulled trailers for most of those miles.

I've never heard of anything like a torque lockout sensor. I think it's an engine miss, either a coil or a spark plug.

Do you just change parts on someone's recommendation? Especially someone that hasn't looked at the truck? Don't you think some diagnostics are in order?

Nonsense, we all know he just needs that CarMD thingy that plugs into that thingy under the dash that will tell him what parts he needs to replace.
