Transmission Won't heat up

[BBGun242]

Anyone else experience their transmission not coming up to "normal" operating temp in the cold (<30°F). I can drive 40 miles down the highway and the transmission never comes up to normal operating temp. Looking for if anyone else has this experience or noticed, before i go back to the dealer that argued the rear axle click was from the wheel slipping on the brake rotors.

The thermostat could be stuck open…that would cause an extended warm up time for the trans.

I've thought the same, however above 30°F it warms up in under 10 miles. Just doesn't seem linear enough to be a stuck thermostat to me. Also I would think it would throw a code since the engine did that to me.

I’m not even sure if the transmission t-stat will throw a code if it sticks open like the engine t-stat will. How are you monitoring the trans fluid temp?

It shows up under the tach in towing mode.

Recently got a COBB AP. My trans never gets over 175°F during my normal driving. Typically runs about 165°F.

I've done some googling however I cannot find any actual part lists that call for a transmission thermostat.

Transmission Cooling - Overview

The transmission fluid cooling system consists of a heat exchanger mounted to the transmission. The heat exchanger has both transmission fluid and engine coolant flowing through it in separate chambers. When the transmission fluid is cooler than the engine coolant, the heat exchanger warms the transmission fluid. When the transmission fluid is warmer than the engine coolant, the heat exchanger cools the transmission fluid. A coolant control valve controls coolant flow to the transmission fluid cooler.

Thanks Wafer.

So watched the old coolant temp this morning too. Looks like my ST came with a 180 t-stat. Which based on what you provided seems culprit.

Help with Trans Temp.
I am trying to get Torque to read the trans temp, I can see the trans temp gauge under the Tow dash setting, but Torque can not seem to find it. Anyone have any luck with getting Torque to find the Trans Temp?
On another note, Torque does seem to find "Boost" and it does seem to be working; but from what I have been reading here there is no way for the computer to report this? (it may be that the computer is just making a guess from other readings?)
