anyone know which wire for the t/c lock up... or even have a ecu pinout or something, my transmission hates me for towing 2tonnes up hills.

Hi Yah

If you are running the 1KZTE...

Here is the ECU pinouts...



To lock it up...You want to supply voltage to SL...


If you want to stop it locking....Put a switch in it and it will interupt the voltage to the solenoid in the box.

I am not a sparkie but I have used a brakeout box to control the auto... Using paddles ..but have gone back to standard.

Hope this helps

be careful if you do wire up a switch to do it manually...if its locked while decelerating it wont be good for the auto

thanks very much. will only be used on accel, although i cant see why it would do any damage using it on decel as well? towing around 2tonnes of trailer without having it locked causes some serious transmission heat issues...

can u change gear with the t/c locked or does having it locked not allow it to change

The normal shift patterns have the TC unlock when shifting gears.
Also when braking.
I have a toyota document which explaines how it all works..
