Transmission slipping.
Great car, I've put a lot of work into her. Until the transmission this week, she's just got a rack and pinion leak, one mismatched tire, and the rear hatch lock sticks. Fixed everything else.
Make me an offer, cash or zelle, come pick her up. She does drive, but she doesn't do 3rd or 5th gear anymore and takes a bit of pushing to lock in 4th. If you don't tow her, you drive her at your own risk.
