Alright so I know that an E Series has a BTR transmission, and I know that the 4 speed BA/BF box is a variation of the same box. I'm wondering if it's possible to get the tiptronic function from the B series working in the E Series box? What's involved? Do you need to change the valve body? Manual Valve? then obviously there will be some ECU mods too. Will a J3 handle this?
