Hello Pet Talkers (small update post 25)

Hi LH, the code was P0753, my car is a 1996 Celica. I've been searching and it looks like it could be anything from dirty transmission fluid to the computer itself to a rusty solenoid, though the transmission shop said the solenoid itself seemed fine.

Thanks for the tip about the tire! As soon as I get the car back, that will be my first project. It looks as though someone hit my car while it was parked in front of the house, and caused a significant tear on either side of the one tire.

I'd start with the tranny fluid, not a flush, drop the pan and change the fluid and the filter.
