Random Limp/Hobble Mode?

[undefined0000]

Alright, I've done a bit of reading and can't really find anything that suits my situation if it is even a problem. I just noticed that my tranny doesn't really always take off in 1st. I think its second gear, maybe 3rd. When taking off sometimes, it feels slow, so I back off the gas a little and press it down again and it downshifts and takes off. My last A/T car did it and I figured it was normal, but apparently these cars are supposed to go down to first every time? When I'm slowing down, I can feel the tranny shift, and whatever its shifting into, its shifting into it pretty hard, it shakes the whole car. I have no CEL and the car does downshift when I really get on the gas. Its just taking off from a stop that feels super sluggish sometimes.

The CEL won't come on for Transmission related problem. Here's a link to check for codes.

TCU Codes

Here's some additional information on the TCU, with pinouts.

We'll go from there and see what you've got going on.

How gentle are you with the throttle? Do you baby it all the time? Try unplugging the negative terminal for 10 minutes and re-try. The ECU/TCU adapts to your driving style after a certain period. Also, does it happen after a complete stop, or is it a slow roll? Because if you're rolling slowly and you get on the gas, it usually stays in 2nd (for me at least).
