Should I sell or repair?

Hi,

I have a 2007 Toyota Yaris Hatchback with about 92000 miles on it. Around winter of this year I started having transmission problems. At the time I didn't know much about changing fluid every so many miles, but I was probably too hard on the car during the winter. Anyway I had to replace the transmission and a bunch of other repairs costing over $2400. A year prior I was in an accident (at fault) and banged up the side of the car a bit. I replaced the doors but the dents are still there (and now some rust) and the front bumper is also damaged. A few weeks ago I noticed the gears slipping again. I brought the car to a mechanic who told me that the transmission seals were bad and leaking fluid. The transmission isn't covered under warranty because it was my responsibility to have the seals checked before the install. I'm sort of at a loss now with what I should do. Another transmission install is going to cost at least $1200, and the car is only worth $2000 if I traded it in for another. I don't really have a lot of money to spend on another car, but it seems to make sense right now to go this route, because I'm putting more money into the car then what it's worth. Just to give you an idea of the cars condition here are some pictures:





Also, the front bumper needs repair, as well as a new muffler and alternator belt. The trunk lock is also broken (seized, likely do to the harsh winters we get here)

Just out of curiosity I put a for sale ad online and without the transmission working I would get $800 for the car max.

Is it worth to repair this car or replace? I can't seem to find any other car within my price range that wouldn't require having a car payment which I want to stay far away from. But then again if I'm paying $1200 to get the tranny fixed that's 10 car payments on a fairly recent and good condition car.

I can't decide and having anxiety thinking about what I'm going to do with this car and how I'm getting to work each day :(
