This new to me 4l80e has a d3 trans brake. It requires the trans brake activation for reverse. So instead of pushing the trans brake button, I am hoping this works. Can someone please check my diagram?? Thanks!!

 

The D3 transbrake requires 12V+ to activate.

 

I swore I read somewhere it was ground?? hmmm. Good thing I posted, lol

 

D1 requires ground? I went through jakes site again and cant find anything about 12v or ground for the d3. I am assuming with your screen name, you are affiliated with jakes performance?

 

for12v+???

 

he is jake...i would call there shop for faster response

 

That should work.

There are instructions on the website.

 

How many amps does the switch need to be rated for?

 

I was in the middle of adding the pin to the trans harness for the brake. I went out to garage to look at connector on trans to see where to put it, and there is no extra pin.....

Could this be because it had the manual control box on it before? Or is there no trans brake even installed in this thing?????

 

Some early units we used a pass through connector on the passenger side, on top of the case.

Otherwise it has to pass through the main connector.

 

Jake can I pm you the original owners name? Would you have a build sheet under that name?

 

We should have records depending on how old it is.

Email them to the shop address.

 

OK, thanks, emailing now. Should be less than 2 years old.
