[Jaay_d5.0]

hello i have a 2019 Gt with a 10 speed im currently at 33k miles and I don’t know much about transmissions as i do with engine but i think i have some trans issues here i notice that sometimes when i accelerate the rpms just rev up before it goes forward has happen a few times even happened on reverse once that i notice. Have any of you experienced this with your 10r80? I do have a roush calibration on the car to keep my warranty.

Yes. Well known and documented concern, as it's constantly learning and guessing (skip-shifting). I had mine reflashed at the dealer at no cost, then drove it normally for a day or so. Butter smooth now.
