and he also states that when he floors it the RPM's go to 4500 and then he finally sees some acceleration... so with that statement it's as if he has no understanding the reason the revs go to to around 4000 is because the transmission downshifts to a lower gear, which obviously ends up being somewhere higher in the RPM range..... dude the higher in the RPM's that you are THE MORE POWER YOU HAVE AVAILABLE AT YOUR DISPOSAL!

Alright I was gonna blow the issue off but today in wet road conditions I hit the gas maybe 25% if that to accelerate from 20 to 40 and my RPM's hit 6k and almost red-lined and then my Slip light came on. This definitely scared the crap out of me since I almost redlined the thing when I hit the accel at MOST half way. I know it was wet, but I've never seen a 2 second delay on a pedal to accelerate instance on any car. The car never lost traction or slipped, it was close but the RPM's were already 6k before the slip came on.
The car works completely flawless in manual when left in 3rd gear I get instant acceleration... it's just when it's trying to decide to shift I guess. I'll do an ECU asap but man that just wasn't right earlier.

Listen,
When you peg the gas from a dig (rolling), you car will downshift. It takes a moment for the downshift to occur. At the same time, your torque converter unlocks and allows the engine to spin up (similar to depressing the clutch on a manual tranny), then gradually (so-to-speak) reengages as your tranny gets into the lower gear. All this DOES take a bit of time, and yes it is sluggish. I did notice a slight difference when I installed my grounding wires (believe me, I could not have convinced myself that grounding wires actually worked before I installed them). If your main concern is shifting quick, the stay in manumatic mode.
A better example of the torque converter disengaging is if you give your gas a partial stab while rolling. Don't hit it enough to cause a downshift. You'll notice that your RPMs will jump 1k-2k, even though you're still in the same gear.
As far as what happened to you on the wet road, your car was working perfectly. The slip light came on telling you that your traction control system is preventing your rear wheels from breaking traction. Your throttle was electronically b!tch-slapped and, even with the pedal to the floor, you won't accellerate until your rear wheels regain traction.
You need a clutch.

What has happening is that if I accelerate hard in 1st gear it will take literally a second or two for it to actually go, then when I shift up to second it will take a second or two to go too. It just revs extremely high before it car actually gets going. Is this an ecu issue? I am not an experienced manual driver, but this really does not make sense to me. If you have any input, please let me know, thanks!

Ok... I'm not flooring the gas like you guys may be thinking. Even if I hit the accel lately half way just to get some decent accel I think it is downshifting into 3rd from 5th if I'm going 50mph. My main concern here is not from 0-40, it is when I am above that speed and accelerate onto the highway or around people.
I was going to just deal with it till my most recent experience. I hit the gas to get around someone and my RPM's hit 6k... she almost redlined till I took the foot off the gas to allow it to shift. I can't tell exactly what is happening, but you should never almost redline in an automatic when going 40mph trying to accelerate onto the highway. It's like it's shifting down into 3rd and then giving it a bunch of gas and not shifting into 4th unless I take my foot off the gas and let it shift.
I am taking all your opinions to heart, but almost redlining in automatic really messed with my head.
