07 Transmission Dying
 

I have a 2007 Mazda6 four cylinder with a 5-speed automatic and the trans is about to die. It's already been rebuilt multiple times so I'm pretty positive there's no saving it. Does anyone know where I can find a used trans that fits with the 4-cylinder and has relatively low mileage? I'd even be willing to get an aftermarket one just as long as it fits with the motor. I can afford to replace the trans but I can't afford a new car so this I why I'm coming to you all. I've tried browsing online but I can't seem to find much? Anyone know any retailers or websites that can help? Thank you
