Car was stuttering, struggling to go. Was told by AAMCO we needed a new transmission. Had that done. But vehicle is still doing the same thing and they’re saying it’s a something to do with the fuel line issue so they changed a couple sensors (for free) but it’s still doing it. We have the car back, but on the drive home the check engine light came on. I’m feeling like we didn’t need a new transmission but it’s already installed and paid for but our car is still not running right. What should I do? Seems like they keep throwing parts at it in hopes it solves it. I just want it fixed.
