I am posting for a friend. He has a 97 auto and wants to be able to run a toggle switch to his TCM and be able to lock up his Torque Converter. I guess he heard you can to that on earlier autos but dosent know how to on his. I know nothing about transmissions, i am just asking for him. Any help would be great. thanks in advance.

the tranny is a 47re and uses 12 volts to power the lock-up selinoid, the 47rh is hydraulically controled but requires the use of a ground in the circuit


also the SEARCH function works wonders.....

Thanks for the info. I tried searching and didnt see what i thought i was looking for. Its not my first time on a forum, but thanks for the info. I think that is what he is looking for. Have you tried this yourself?

 

not in it's entireaty..... got the switch mounted and wire ran found the wire in the harness..... waiting to install trans temp gauge so i can monitor it as this will heat up the fluid FAST i'm trying to prolong the inevitable... i'm still on a bone stock tranny....

 

talk to dunrite converters they lock up in every gear up or down, they seem to be very knowledgable.

 

Better clarify that before someone gets the wrong idea......a locked TC will COOL the trans, not heat it up. Unless it's slipping of course. Fluid shear in the TC is the #1 heat builder in an auto, get rid of the shear and get rid of the heat.

 

That doesn't have anything to do with the TC itself, it's the VB, really.

Keep in mind that a lockup switch on a stock trans/TC is NOT a good idea.

 

It's often called a "MYSTERY SWITCH". Try searching for that!

Bet you find a ton of stuff.

 

I gave that info to my buddy and it is what he wanted, thanks to everyone. I dont agree with doing it but that is what he wanted. I just gave him the knowledge he can do with it what he wants. thanks again guys
