Yes there is no reasion why it won't. The temp sensor is a special resistor that reduces its resistance as it gets hotter. At 20 degs C/68F it has a resistance of about 2.5Kohms At 80 degs C/176F it goes down to about 330 ohms. Which brings the ATF light on ,and changes the shift points to move more ATF through the cooler. Running a wire from one side of the sensor, to a switch, to a 220/330ohm resistor, then back to the other side of the sensor wire, will drop the resistance to a level low enought to do it. If the resistance is too low, the TCU may post a code. Harvey.

Can't see any side effects to it,other than the ATF light will be on, in this mode, so it can't signal a high ATF temp problem. Harvey.

Re: Power Mode
Thanks alltrac! I never knew that... I do see that AT oil temp light at start up. Cool!

Does anyone know how the power mode switch works in the Euro model SVXen? Does anyone have a wiring diagram from one of these "switch-equipped" models? I suppose all you'd really need is a quality wiring diagram to tell you where to start. |

I'm gonna do this when I'm back home this weekend
Maybe I rewire the original "ECON" function to some other switch (hidden), and wire the new "POWER" function to "ECON" switch, nice to have it handy in case of "emergency" Maybe I relabel it to "DECFON MODE" ..and UberRoo, got me there ...didn't read and understand the post in full /Sonny

deruvian, the "Euro" model does not have the "Power" switch, that's why I'm trying to implement one

I think only the JDM model has one, maybe we ask Joe (svxistentialist) if he has a wiring diagram, he have a JDM (I think?)

A couple of things you may consider, (or already have,) is that (1.) when the TCU is in power mode it tends to hunt for gears, and (2.) the "power mode" which is caused by hot ATF may not be the same power mode that is caused by rapid application of throttle.
In normal operation, there's a margin between how much throttle is needed to get a downshift and how little throttle is needed to get an upshift. This 'null zone' keeps the transmission from switching gears at the slightest change of throttle. In power mode, the 'null zone' becomes very narrow and almost undriveable. The next time you're at freeway speeds, romp on it and get the TCU into power mode, then abruptly let off the gas for just a second - maybe a couple of times. Notice how quickly it changes gears? It's like an annoying hiccup. If you do this a few times, you'll find the transition point (where it shifts) on your throttle pedal. If you hold the pedal at that point and just wiggle your foot slightly, it'll jump back and forth between gears like crazy (as long as you're in power mode.) You can do this at low speeds too, but it's a bit harder to do as the TCU goes back into normal mode rather quickly. Power mode works very well if you just want to accelerate, but the TCU gets very confused if you want it to do anything else. I think you'll find it very undriveable. Don't get me wrong. Experiment with it. It'll probably be a pain to drive, but a lot of fun while you toy with it. If it works, you'll be a hero to many. |

I regularly drive with the power mode switch on because it makes the car feel a little more responsive - it tends to be in the right gear at the right time, rather than being one gear too high. Phil. |

b3lha,
I would not disbelieve, but would be surprised if your Power Mode button causes the same performance that the automatically activated power mode causes in U.S. cars. I know that the power mode does cause some undesirable behavior in my car, but because the mode is used only in great moderation, it's of relatively little consequence. How does your Power Mode button work? At what speeds does it downshift when coasting? How is it wired? It would be very interesting to know if the behavior of your manual activation is the same as our automatic activation. It would also be interesting to know where the wires go. Perhaps you share the exact same TCU, and the only thing missing from ours is the wiring and switch. That would be very cool. Personally, I like driving the torque-monster. I love being able to climb steep hills in high gear with the torque converter locked up. ...but your right, it's not sporty, and I understand why the shift points would not suit your mood if you're feeling frisky. |

JDM models
JDM models have the same 'automatic' activation of 'Power Mode' as US models. Plus 'manual' activation via the console switch.

I find the downshift points difficult to determine, but at WOT, it seems to upshift at the 6500 redline: to 2nd at just over 40mph, 3rd at about 85 and 4th at about 115-120 (although I rarely go that fast). Phil. |

Does anyone on the boards have a JDM ECU or TCU wiring diagram? |
