I have a 2015 TLX V6 SH-AWD Tech with 10,800 miles. I had a software update done last month at the dealership and they asked me to drive 500-800 miles to see if it gets better. It did but in the meantime, my seat was feeling loose/rocking so I made an appointment for that and also for them to look at the trans data. They asked me to go on a drive with a mechanic so I did. He took a bunch of screens shots of the transmission between 1-2 and 2-3 gears and said they'll send it to Acura and see if they're willing to put in a new trans. They called me few hours later and said I'm getting a new trans and a new seat frame. Great customer service but all this on a car with 10K miles already that cost $40K? ****...Anyway, I have a 2018 TLX 4 cylinder loaner, the transmission in this car is amazing but it's definitely lacking the power of the V6 and I do miss my SH-AWD. I'll update next week around Tuesday how the new trans is feeling, hopefully they put it together nice and tight.
