2012 Toyota Camry transmission failure at 113k miles, what to do
I purchased a used 2012 Camry at 101k miles last October. The car is almost at 113k miles now but the transmission got destroyed. What happened was the torque converter started shuddering, which is apparently a common problem in some models between the 2012-2014 model years. This eventually lead to transmission failure. The fluid was changed at 103k miles by the dealership so the fluid and magnets should have been clean but it was full of metal and the fluid was black and burnt. I intended to just replace the torque converter to stop the shuddering (which is how the metal was discovered, when the shop I paid to replace the converter were taking it apart) but the shop says that they have seen this happen before to cars with a shuddering torque converter and usually the transmission fails. They will not charge more labor to install another transmission but advised against driving the old one as-is as it may fail then I have to pay labor again to replace it.
Anyway I'm not really sure what to do. I like the car but it's not worth much and I don't know if I should sink a bunch of money into it to get it running again or not. A used transmission would be around $2k and rebuilding the existing one would be around $5k. I cannot seem to find a remanufactured one that is an actual OEM remanufactured one and not just a rebuilt one being sold as "remanufactured".
