Don't actually need to use T/H once you start manually shifting out of D (this is direct from Mark K. from a thread several years back, where he gave me some schoolin')

What is are your ect and eot after a good long (12+ hours) cold soak? The fact that your ect is so much higher than your eot says there is a good chance that there is a problem with the sensors...
Do you have an aftermarket air-to-oil cooler?

Factory oil cooler... generally after a soak they are real close to the outside temp

As a troubleshooting step, I believe you can swap the sensors, we want to see if the temperature follows the sensor or the medium. Please though, can someone verify whether or not you can swap the sensors?

Generally if the sensors are there around the same temperature as ambien temp they are all okay
But you also need to watch them at the truck heats up and make sure that they do not jump around This temperature rise should be steady

Normal operating temps vary from EOT 196-204.....ECT 192-200....They stay pretty close to that. Even pulling today, there was never more than a 10-15 degree difference, until the ECT went way up and wouldn't come down.

Can you hear the fan engaging, increasing speed and going to full on? My guess, because he says the water pump is replaced, and the thermostat is replaced, is the viscous coupling drive or the wires to it are fried. Since he has an sg2 he should see full doran rpm by about 218 or 219 degrees right?

They generally rise together, water temp first, then the oil catches and then passes.

Ok made it home today, finally got to truck. after 11 days of sitting, the EOT 84, ECT 84 outside temp was around 80. Drove the truck about mile and a half to the house, from start up to the house, no idle time straight driving 35mph, EOT 140 and ECT 180.....Did notice the turbo sounded way different like has a bad leak with a whistle sound....

I agree with the guys above thinking it's a sensor. I haven't had to swap them myself but it's been posted many times the two sensors are the same part number. They'll swap right out.

It keeps sounding more and more like a sensor problem. Pull the ECT sensor and check it for any accumulation of silicate or rust.
