So the other day I'm driving my 2005 TL, and it went into limp mode. Then the VSA flashed and it would not accelerate. RPMs was high. So I pulled of to the side and the car was stuck in DRIVE. I turned off the ignition and then was able to start it back up and put it in park. So I called and had it towed to shop who said the tranny was gone. I asked did they the codes and they said no. They then offered to rebuild my tranny for $3600, I said wow! So I went and picked it up and ran the codes.

P0420 catalyst efficiency below threshold bank 1
P0128 coolant temp below thermostat regulating temp
P0125 closed loop fuel control efficiency coolant temp
P0721output speed sensor CKT Rng / performance

I need help bad. I did recently put in a radiator and didn't clear codes. The dealer where I got the car a year ago replaced the catalytic converter.I did drive it from the repair shop with the VSA turned off.
