Well, it's official! Car is dead. Won't shift into gear anymore, likely some solenoid that's fried from overheating due to driving it without minimal fluid in the transmission a couple times. I checked the fluid and it was clean/perfect, no leaks, at the full line. When you put it into gear you hear some clicking/noise, but nothing. Towed to the junk yard and he's got a 2014 mint Toyota Corolla with 63k kms. Good choice. Well, considering the abuse, and the fact that he got several thousand KMs out of it, it was a small investment to keep it going until now.
