Why is my car doing this?
I have a 700R4 for my transmission. Here's the scenario:
I'm at a dead stop at a red light.
I have the gear shifter set to OD.
When the light turns green, I go like I usually do. I don't gun it or anything.
What happens is that, while I'm in first gear, the tachometer rises as it usually does, but all of a sudden it refuses to go above 2,000 RPM, and the car feels like it's waiting for me to change gears, as if it was a manual transmission; real stubborn. Once it changes gears, I get a jerking sensation, as if a shift kit of some kind was installed with the transmission.
I found that if I ease off the gas pedal for a split second, then the car shifts from first to second gear. This is the case for second and third gear too.
Although if I'm in OD and floor it from a dead stop, I notice that this doesn't happen anymore, except now the car shifts at 4,000 RPM in each gear.
Is this normal for my transmission?
Info on the car is here. You might notice that I made a table with the 700R4's gear ratios: that's just what the factory said the settings were for a stock 700R4; I'm not sure if that's the case for mine.
Thanks in advance.

Try this: To adjust the TV Cable skip the book method and do this: Press the 'D' shaped lock button on the adjuster and loosen the cable setting (The black housing that the metal cable is in will move forward). Now, have someone floor the gas pedal while you check to see if the throttle plate is open all the way. Usually they are off a little and will wiggle. Do whatever you have to do to get it open solid. Now, with the pedal still floored, press the 'D' button and pull the cable casing (the black tube) back as hard as you can (putting maximum tension on the metal cable) and release the button. You now have the engine, tranny and gas pedal all in sync at WOT. Mark the cable casing so if for some reason it gets moved you can know where to put it again. The problem with the 'self adjust method' is that it bends things and puts them permanently out of whack. It is also the full TV setting, which is theoretically what the GM method does.
