what EXACTLY is a J-MOD??? thank you

[bawazir]

something to do with transmission

You take the valve body out of your transmission, drill bigger holes in it a various locations, replace a few springs and wha-la you have a J-modded transmission.

Faster more firmer shifting.

You can also buy a valve body already setup with a J-mod already done to it with springs etc at www.bc-automotive.com (http://www.bc-automotive.com)

Hi
I was thinking of doing a J Mod before I do a trans flush & use RP.
Does it make the shifts faster & would a new tune be needed for it.
:burn:

[justbob]

Yes faster shifts. You may want to dialback your line pressure if it is allready turned up high in your current tune.

[Mr. Man]

If you already have a tune will the J-mod be beneficial or will you need to modify the original tune to compensate for the J-mod?

If you already have a tune will the J-mod be beneficial or will you need to modify the original tune to compensate for the J-mod?

And then add the J-mod after the tune you might find it shifting too hard for you.

I havn't done either but I would think it would be a little extream with both done.

If the tune you have has higher line pressure to firm up the shifts you will have to return the pressure to normal.

That's what I was thinking just wanted to confirm my thought process.:)
