There is no TSB as the ecm already has the software in it, they just have to turn it on. I had mine done once when I had the oil changed and they showed me how it was done. Took about 2 minutes.
If you have the manual trans. it's a little more involved. I believe you need to purchase a special part (can't remember exactly what it called) to bypass the clutch. It can be done though. My neighbor did his himself.
