Got the thermostat putting it in now. What should I use for thread sealant? Thread compound or Teflon tape

The tape is the best route. No mess!

I used Permatex thread sealant, i'm not a fan of tape in these types of applications .

The cooler line is about 30 PSI.

Be VERY careful with any thread sealant! If any gets into the cooler line it will find it's way into the trans where it can stick a valve and cause a transmission failure.

I ended up using only Teflon tape as recommended by company.. so it got it hooked up and went for a test drive all uphill for about 7-10 miles and this is what I ended up with . This is as hot as it got. Never dropped below 150 even coasting.. thought these were 180 thermos...

Ok, the thermostat starts to open at 160* and is fully open at 180*. It always allows 10% of the fluid through regardless of the temperature of the fluid. The other thing to keep in mind is the outside temperature cold air is going to cool better than warm or hot air. You're in the mid 160* so that an improvement. Why would it drop below 150*? Theres 18 quarts of fluid, once it hot it doesn't cool instantly.

Ah I was thinking itíd stay at 180 but I saw the Knick marks and what looked like grease.. wasnít sure if it was a defective part someone had and returned then shipped to me.. ok so 150 is a good temp to rub at as far as condensation issues. Thanks for the help fellas wouldnít have got this far without any of it..

My gage sensor is in the test port and reads 10-15F less than truck (PID).

I agree Brian, the PCM reading gets hotter faster than the test port but the test port eventually catches up and is within 10*.

The ATF in the cooler line is hotter than the temperature in the transmission. The thermostat operates on the temperature in the cooler line. It seems to me that everything is working as it should.
