Kuruption

I will save the background of this story for another day...I have an 03 TL-s and when i got my car back from collision repair, my emissions light came on. Figuring that the codes just needed to reset from the disconnected battery, I thought nothing of it. Until, that is, for the first 30 seconds to 1 minute (most of the time but not all) of the initial drive my car seems to "bog" out, then it will pick up if I let off the accelerator. After that my TCS light comes on and everything is fine. The codes that I was given were p0730 (Gear ratio incorrect?) and p0132 (O2 sensor?).

Can anyone tell me what this means? And please dont tell me it is the tranny cause I just had it replaced 20,000 miles ago and warranty is up. Thanks.
