Delayed response and jerky take off when trying to accelerate

I recently had a charging issue with my 2015 Chevy Suburban LT. I changed the alternator and everything seemed to be fine. However, the next day, I noticed I was having an issue whenever I drove it. From a complete stop, when I press the gas to accelerate, my RPMs rev high and there is a delayed response before my car "catches" and jerks forward into gear. Once I get going, I'm generally fine but when I'm in traffic and press the gas for a quick acceleration, the delay and revving RPMs issue occurs again. I've driven it like that for a few days now because I didnt have time to take it to the shop, but the issue seems to be getting more pronounced.
