I read the tech article on how to make one but it didn't explain what it did exactly, and I was also wondering if it is such a good idea or not.

 

Just unplug the connector going to your tranny underneigh

I didn't read the tech article you are talking about, but if your talking about putting a switch in to lock out the converter clutch, simply splice into the tan/black wire from your ECM. Before you go cutting wires check the wiring diagrams for your year/make car and make sure it's the correct wire! BTW what year is your car? Let me know what you are planning to do.

 

Its an 89 iroc with the 350 tpi and th 700 I understand how to do it but I'm wondering what it does exactly and what use is it. Also is it not hard on the drivetrain

 

Are you trying to lock IN the TCC or lock it OUT?

Locking it in will make the TCC lock up as soon as the transmission shifts into second, which is supposed to give you better throttle response and a better launch. Used excessively this is probably bad for the transmission.

Locking it out will prevent the TCC from ever locking. Your cruise RPMs will be a little higher, and gas mileage will be a little lower. The 700R4 is designed to make maximum line pressure with the TCC locked, so always running with the TCC unlocked will cause things to run a little hotter. Probably not anything that an aftermarket cooler couldn't handle, but some have reported that they've slagged their transmissions by running for extended periods with the TCC disabled.

 

Its hard on your tranny
