cam someone school me on this subject? I'm trying to see what i need to do to have 4th, my lock up cylinoid is cut from the harness.i have another one but no harness! can i just wire it to a switched 12v and switch it on when I'm in 4th ? or will it burn up?

 

I'm sorry is a 93 700r4 in a93 Trans am i just rebuilt the Trans

 

Do you really want to go to all that trouble for a $34 part:

BTW - a 4l60E internal harness with TCC solenoid is only $32:

I don't think it would burn up getting engaged, but you will have to switch it off as you slow down or the car will stall. It would be very unwieldy.

 

do they have one for mine?
