I have a bad missfire on my 2012 fwd. no cel is on and it jerks around when I hit 3rd to 4th gear like it’s cutting in and out had the trans checked and it was fine the rpm needles jumps around while it’s doing this and you can feel a hesitation when accelerating

I also have an oil leak somewhere I can see it burning off the exhaust

Even though no CEL, have you scanned it for codes with a scanner that does more than just the basics?

I had low rpm jerking on my 2008 and 2012. No codes. Both times it was the torque converter. Change out your trans fluid twice and add 2 tubes of Shutterstop. If it improves, it is the torque converter
