At what temperature does this occur?

Best Answer Mark helpful

not sure of actual temp but once the the transmission gauge shows it has come up to temp

as thought - electronics are subject to this type of failure, ckt boards, caps, etc. Could this be related to the tcm? is there some other component in the circuit that might be subject to temperature failure?

I also suspect a control issue. This is a job for a good transmission shop.

What condition is the ATF in?

transmission if in great condition where is the control fuse located - in fuse panel under what name or #

by control issue to you mean the tcm or is there an other component that is in the ckt/

Controls = electronics.

transmission if in great condition since the tow haul button is basically a gnd to the tcm which then changes the shifting algorithms . This signal once the temperature gets hot does not get sensed or that portion of the tcm ckt has a failure. is there a way to test the tcm to determine if it is ok?

Testing transmission controls is past my pay grade which is why I suggest a transmission pro.

The tow/haul feature is electronic. What it does is it alters the shift patterns of the transmissions. It also prevents the overdrive feature from kicking in. When engaged, the vehicle will also not coast, meaning the transmission is used as a braking feature. What you will need is someone with a live data recorder to check the perimeters of the transmission under driving conditions and under load.
