The TRD Supercharger Fit Kit for the Automatic tC will be released on Monday. We would like to recommend to any who are planning on buying the S/C do not tamper with the unit. (pulleys, nitros, etc.) It works great as it comes out of the box.

FINALLY!! so are saying that even after we get the fit kit installed, we can't use aftermarkey s/c pulleys? also, no special reflash for the auto like rumors have been saying?

i cant wait!!!

And they said this day would never come!!!

Is the HP gain any different from the Manual with the SC?

Goddimus

That is the same exact thing I was wondering too before I even think about purchesing a SC.

Shoelesscraig

I'm wondering the same thing...anybody who orders this thing for the auto, please post reuslts ASAP!!! You are like obligated to dyno and satisfy our curiosity, haha!! We just gotta gotta know!!

TheQuietThings

THIS THREAD IS USELESS WITHOUT DYNOS!!!!

The HP gain is the same as the manual. That's why it took TRD so long to release the auto kit. They did not want the guys in the automatics to have less of a gain than the guys with the manuals.

PghtC

so I assume the increased the power output somehow to compensate for the parasitic loss in the auto tranny compared to the manual? Is that a correct assumption based on your statement?

Shoelesscraig

any word on whether or not the reflash makes the tranny shift any differently or not??

trdsparks

Yeah they did something in the tuning for it to compensate for the some of the parasitic loss. Yes the extra re-flash will change the shift points. According to TRD it will perform the same as the manual.

The re-flash that comes with the kit has to be done and then another part has to be loaded into the ECU from the TIS computer at the dealership. Just want you guys to know that.

PghtC

Yeah, I figured the tuning is holding back a good amount of power, and this really does prove it. If they can get the extra power to compensate for the tranny losses, that means the Manual application could be tuned to get at least that much more power. Not fair.

eh well. It is good that they actually planned for this and made them equal.

trdsparks

There isn't that much loss through the auto tranny or not as much as you may think. All they really did was change the shift points of the auto. But in do that is made the same power.

TheQuietThings

I'm pretty sure the auto tranny shifts at redline... what else could this reflash really have done?

trdsparks

It's not going to shift at redline. That I can tell you. It's still going to drive like a normal car and if you're not getting on it.

Shoelesscraig

Well, I'm not sure what they did in the reflash, but I can tell you this. I own the automatic, and if I go outside right now and start driving and push it to the floor, my car will go to redline and shift every time. Granted, it slides into the next gear (which I hate) but it does go to redline.

TheQuietThings

So when i floor the car, [WOT], its not going to shift at redline[6250 RPM]? It shifts at redline now when i floor it. I don't think it would make sense to lower the redline. the auto tC makes most of its power between 4k and 6k RPM, lowering the redline would mean that during WOT runs, the car will be revving around 3-5k RPM which isnt its optimal powerband.

trdsparks

Yes it will if you push it. Sorry I should have been more clear on the. What I was meaning is it's not going to hold every gear to redline under normal driving. If you pust the car it will hold the gear longer.
