I have 98 v6 automatic mustang and my friends were recommending this thing called a J-mod? I was wondering if there is a place thats sells these and do I also need a tranny cooler, thanks.

 

You do not need to go and buy anything other then one drill bit and a tranny filter and fluid to do the Jmod. Its a very simple valve body mod that can be done in the driveway by most people who are some what mechanical.

What it is does it allow more fluid to flow to the bands and get there faster which means less slipping between shifts and that means less wear and less heat. And heat is the number 1 killer of trannys. The extra benefit is the firm shifts you get, which are pretty sweet as you will be able to bark the tires on the 1-2 shift on most cars.

 

So is there a link that shows you how to do this? I am just a rookie on doing things to cars.
