Hate to raise this one from the dead...but I have been throwing the AT light over the last 3 weeks and it looks like it's getting worse. With that being said, I took it to the Mazda dealership, they showed no codes and oddly they couldn't replicate the issue while driving it over 2 days. They want $1100 to replace the TCM as a guess at fixing the issue. Not going to pay that for a car I paid $1800 for. So, I just want to make sure, I should be looking one of the following parts for my 08 touring?
