What is my transmission NOT doing that it should? Everyone keeps saying there's "problems" but no one can seem to quantify what exactly that means? I mean, what SHOULD the transmission be doing that it isn't. This is getting very frustrating because it's like pulling teeth to get any specific answers. It seems to be driving like it used to and I thought the Lextreme TC would have kicked up the torque a notch in the low end, but it just doesn't have much oomph. I['m not expecting the car to do burnouts, but spinning the tires would be nice. Maybe I'm just expecting too much from this car. When I think of power, I'm thinking what my Taurus SHO used to do which is night and day from what this car does.
Sorry to be so vague, but your description of the cars behavior is vague as well. I can't tell what the car is doing from your description, I just know that the words "surge" and "lurch" are not words you want to hear when referring to a cars drivability. Acceleration should be "smooth", and "consistent" throughout the RPM range.
You said: So far, my car seems to lurch off the line.
What exactly does that mean? Because to me it sounds like slipping/shuddering clutch engagement. Or maybe you describe a strong burst of acceleration as "lurching" and everything is fine...Tough to say without a more accurate description of symptoms ya know?
Then you said: 1st gear still surges to redline, but it is still accelerating at a very even keel.
What the heck does this mean?!
Maybe nothing is wrong with your car and it's just the way you describe normal tranny operation, I don't know.

Yes sounds like an internal trans issue such as a torn o ring or a torn/chipped valve body gasket allowing pressure to bleed off thus not giving proper line pressure so I would verify the line pressure 1st

They wanted me to bring it back after two weeks. I'll ask them that. When I first brought it in, they thought that may have been the issue, but they checked it and it wasn't the issue and it was the forward clutch. They rebuilt it and I do notice a difference, it's just that the transmission behavior is inconsistent. Sometimes I'm able to do a 0-60 in six seconds flat. The next time I try it, literally right afterwards, it will be 9-10 seconds. Sometimes it will have a sudden burst of power if I've sat for a minute in idle. If I try to do it again, it won't do it. It's like every other time it will behave sluggish.

well with a torque converter mod you wont notice anything at all if your at idle and you stomp on the gas. what you need to do is stand on the brakes and put enough gas so that the car will try to roll forward and then let go of the brakes and stand on the gas.
if you idle and then stomp on the gas you would accelerate from a stop the same no matter what the stall speed or what TQ you had. but if you did like i described then the higher stall TQ will have an advantege

A converter's "flash" speed will make a difference if you just mat the pedal off idle. In fact, it was the best way to launch my Grand Marquis (9.9 @ 73 in the 1/8th which compares well against any SC) Power braking produced a lower 60ft every time.
Until this wire is cut the car's ECU is fighting power production in first gear. It is working to give you "Lexus" comfort and it does so by wasting power the engine produces. As enthusiasts we want this power back and luckily it's easy to do. A higher stall converter might mask this power loss but it does nothing to counteract the ECU's attempt to ditch power by lowering line pressure.
