turbo 700 wiring

[johnb44]

has anyone hooked up a turbo 700 with lock out feature and how did you wire it for no computer , auto electrician up here didn't really know and the auto bloke told me one thing then changed his mind so im confused it would be good to get it hooked up before the trip to Bathurst smile emoticon

I have heard you can get kits to do it, but when I did mine I changed the wiring inside the box slightly to allow the over heating feature to work, then wired it so it would activate the lockup only in 4th and with certain vacuum (using a vacuum switch)

it worked ok, only meant you needed to put it in 3rd for town etc then click into 4th for 70-80kms and above.... and I used a b&m ratchet shifter so was easy to do.

so in the picture below there is on the left what the internal box wiring normally does, then on the right my modifications.

OD = over drive
OT = over temperature

in normal operation if the box gets too hot for example from slippage due to the converter not being locked, then it will force the torque converter clutch to engage to help in cooling ... I have never had this issue when I did it, but it was in a lightish torana and I never really towed or anything like that .. but I also ran an external oil cooler which I would recommend to anyone doing it anyways.

I've heard of people using a high beam floor switch to do it, but it becomes more annoying and not as seamless, it can lock still when you pull up whereas my method will always unlock before you stop and it also unlocks when you put your foot down to overtake etc.

thanks I think that makes sence

it makes more sense when you see the wiring inside the box too!

I installed a th700 with turbo 308 in my cfl 4years ago using aTCI 376600 kit with modification to suit the aussie box as it has an extra heat switch internaly.The converter locks up when the conditions are right,steady speed etc, but drops out on hills under load or when the brakes are used
