? or is it another part that i will need to use? someone was telling me something i needed and i could swore it was this

 

Yes unless you want it on demand... I just have a neutral switch that I have for highway driving. I just flip it on when I am cuising on the highway. Thats all I need it for. You too....

 

hmmm really, much better than $80 down the drain, how would i hook this up? any pics? thank you BIGJON

 

Read this post first.

Then remove the pan and fluid filter. And rewire the solenoid so that the wire from the solenoid goes to one side of the NO PSI switch for the 4th gear switch. Hook another wire from the other 4rth gear switch termenal to the plug that goes through the case. Wire your switched (ignition) power through the brake switch on the brake pedal (for the original lock up cut-out) and to the plug on the tranny.

What this does is when the car is running, power runs through the brake switch (unless the brake is depressed) to the tranny and to the NO 4th gear PSI switch. When the treanny shifts into 4rth gear, it puts PSI on that switch and closes it locking up the TC. When the tranny downshifts or the brake is pressed the voltage to the plug on the tranny is interupted and the TC unlocks.

Hope this helps, if you need help just yell.

EDIT: I used my stock in-tranny wiring harness to get this done. I didn't have to cut it up except where I connected it to the TH400 tranny plug. Also if your solenoid has 2 wires just ground the red one so that you can use the old wires without cutting them. They are a special wire that hold up in the oil and heat.

I am in a hurry right now or I would right you a book and I am typing all this off the top of my head from memory. LOL! I hope I have left you with no missunderstanding or bad information. Ask questions if needed there are no wrong questions and I will respond as quickly as I can.

Good luck.

 

my buddy has a 4l60e out of a 95 z28 he wants to sell to me, will i still be able to use this wiring with it? i know its different, but what would i need to do, is it even worth it? thanks

 

I am sorry I thought you were talking about the 700R4. This diagram won't work for the 4L60E. I think you have to buy a computer to use one of those without a stock ecm.

 

no no no, dont get me wrong i have a 700r4 which im 90% sure im gonna use, but i was wondering if it was worth putting in a 4l60e, id like to save the money and just use the diagram you send me a link to, (life saver), thanks for all the help, again i was just trying to figure out what was needed for the 4l60e swap... but this thread is pertaining to my 91 700r4 in which u gave me all the info i needed, when i get that far into my swap ill post again if i have problems.... thanks again

 

I don't think it would be any better to run a 4L60E vs. a 700R4. But that is my opinion, I am not sure if the inards are any differen't in the 4L60E vs. the 700R4. You'll have to ask probuilt.

 

"4L60E" and "saving money" don't really go together. If you used the 4L60E, you'd need a controller for it, which makes it far more expensive than a 700R4 or a 4L60.
