It just seems like the tranny would need to be hotter than 100?? But idk

Outside temp has been below 0 for a while and the trans temp read in the negative teens this morning. I put the keys in and let it idle for about an hour (got sidetracked and idled longer than planned). Trans temp was 140 when I came back and quickly cooled down to around 106 after a few minutes of driving. Shifted great (didn't romp on it to much). Will be doing this over the next few weeks sadly.. might be time to switch out my truck for the wife's ride.
