Hi Scotty,

I've bought a 2010 Toyota Matrix base model with about 126k miles on it in August from a private seller. In September, with only a few hundred miles more miles on it, I got my transmission fluid changed at a small gas station that had mechanics working out of it. The car was shifting fine when I bought it, and even after the ATF fluid change it was working and shifting fine. A couple of days ago, around Jan. 25th my car all of a sudden popped out of gear and started to slip when I was coming home from New Jersey going up a hill. when in drive, it was like it was in neutral with the RPM's shooting up but the speed not going up by much at all. I put the transmission into "3", to the left of the "D" icon, and it worked better, enough to get me home and drive around town now, but it still shifts hard and starts screeching at 3k RPM. The car currently has around 138k miles on it. I went to a Toyota dealership and the technician said that the ATF was overfilled, and the fluid was a chocolate milk color and smelled burnt. He also found the trouble code P0751, shift solenoid A stuck off. Do you know if changing the transmission fluid caused the car to starts slipping, or was it because the mechanics that changed my ATF fluid overfilled it? I also use my car to haul heavy electric scooters as a business and did Uber as well. This really sucks! Thanks for any help on this!!

tranny is damaged now, no doubting that. Probably best to put a rebuilt in and not even try to fix that one

Scotty always recommends not to change fluid with high miles can cause more harm.
