What does everyone's trans tempget to with or without a load. Im not complaining I just want to make sure its normal, in my truck I drive about 30 miles before my temp gets close to 130f. I live in Iowa so its pretty cold in the mornings. Should it be heating up faster or is this normal? Highest I've seen it get to was 190f because I had to pull someone out. Just curious for everyone's input.

That's normal. There is no thermostat or any other temperature control on a 4R100. The coolers see full flow all the time, hot or cold. You can warm it up faster with a piece of cardboard to cover the aux cooler.
