Is the Yukon starting out in second gear when it is sluggish?

Doesn't seem to be starting off in second. But I've seen people with that problem. Just had a transmission service done on it but it was running like that beforehand. Just bought the vehicle about a month ago and it has around 140k miles. Running a p0446 code for evaporative emission system, vent control circuit. From what I've read the code problem wouldn't cause it to run abnormally

So it may be possible that it is starting off in second gear. Any ideas? Thinking a solenoid maybe. Fuses all look fine. Of course there are like 50 of them between the two fuse junctions lol

Same problem with my 2010 Cadillac Escalade. It’s pedal to the floor or no go, good luck pulling out in traffic or trying to pass someone. It’s ridiculous.
