I was on the highway and went to pass someone, the car downshifted but went nowhere. It revved to about 3k and held it and then upshifted but the car acted as if it was in neutral (but the revs felt as if they were under a load). Once i let off the gas, it jerked as if it caught itself. I grabbed this video as it was doing it.

Im also having engine issues with this car so it may not even be the transmission that is causing this.

I am not sure how to tell if a torque converter is going bad, but it looks like when it's unlocked, it's not moving your car forward, but when it's locked, you're good. But, I believe you'd have problems moving your car in 1st gear from a stop as well.

Have you checked your fluid level lately?

My fluid level seemed within the tolerance. It seems to only do it over a certain rpm also. If its connected to my other issues with the engine, the warranty better cover it.
