TC lock-up

How do you do this?

I mean... is there a way to do this manually?

Or do I need something else?

there is a write up on this. but all you need is a switch an 2 wires. hook one to pcm tc loc under the hood. the other wire to ground. when you flip the switch tc will loc. do NOT use under 1100 rpm.

just search tc lock

Robby, pin number 54 on the PCM, purple and yellow (purple w/yellow trace). Ground that wire and voila, locked-up! Put a toggle switch in the ground so you can control it. Like stated, about 11-1200 rpm is all I'd let it come down to before unlocking it.

Will this prevent the tc from locking up normally on its own?

No. If you do not command TC lockup the PCM will do it using its program.

Is there anyway to disable the TC from locking up all together?

Why would you not want it to lock up?

What kind of switch would you use for this, and can you have a lighted switch like a DPDT switch or somthing to not back feed power threw the ground wire?

A TC that never locks up is like a slipping clutch in a manny. Poor performance, lower mpg and a whole of heat. That heat will be transferred to the tranny via the always circulating atf. Neither the TC nor the tranny would last long.

Iv'e been thinking of doing this to help with braking when towing in the hills.Can this cause any problems with the tranny and long as you stay above 1200rpm's and if you were to forget it was on , it would be like lugging in high gear when you come down under 1200 rpm's
