2012 Genesis 3.8 not shifting properly.. or at all.

Bought this baby @ 95k ish miles 2 years ago and the problem started about a month after having it. May have floored it a hand full of times in that period (loved the car) but drove it normally for the most part. This issue arises / goes away almost completely in 3-5 day increments…

Mostly only happens around the 10-40 mph range but it’s really whenever I’m accelerating (idk, I know nothing about cars). Upon accelerating, my car won’t shift/accelerate and my rpm’s will SKYROCKET (if I let it) from 2k to 4K+ and will easily hit 5k if I keep on the gas. So I’ve learned to “catch it” each time it does this and let off the gas so my rpm’s will level / drop. If I DONT do this my car will jerk like no other and so I’ve gotten very good at catching it early.

No joke, on a bad day this will happen every 10-15 seconds if I’m driving in the city and need to stop/accelerate often. So you can imagine my annoyance.. but the wild thing is is that it will completely go away the very next day.. like it wasn’t even happening.

After about a year of driving it I had my dad take it to a reputable auto body shop (Ik, I shouldn’t have waited that long) and the dude basically said it was a simple, cheap fix and all that was needed was to put a clip? on something and that I was good to go. Problem came back weeks later.

Again, I really don’t know anything about cars so I’m wondering if this would be a serious transmission issue or if any of you had similar problems in the past.

Slip-bang/jerking/violent shifts are a common issue with the 2012 transmissions as they get up in miles (75k+). The issue won't get better on its own,. Prolonged use w/o fixing is neither good for the car nor the safety of you and those around you. It can be repaired (forum members have DIY'd it, but based on your self-description you should pay a professional). May need one or more valve-body solenoids replaced (most common failure). Can be done with the trans still in the car. Most dealers usually try to replace the entire transmission for $10k+, but it really only needs about $500-1000ish worth of parts and labor. Find the best transmission shop in your area and pay them well to diagnose and fix it correctly.

I just went through this recently, and what I found out was the valve body solenoids are not available. Multiple shops and two dealerships said I would have to replace the transmission.
