Thread: j mod has anyone done this

Is the j mod hard to do and does it work good

J mod?

Yeah it where you take the valve body out of youre trans bore a few holes out and it make youre trans shift a lot tighter and faster and takes stress of youre clutch a friend of mine has a crown vic he told me about it it is really noticable in his car

Never heard of that so I wouldn't know lol. Drilling into parts in my transmission doesn't sound like a great idea to me. If you want to change your shift points and firmness you can always get a programmer. Save you a lot of work, but you gotta pay for it.
