A518/46RH transgo TFOD-HD2 shift kit install

Well Crap.

Just got off the phone with Transgo, they couldn't believe it doesn't have a PT body on it. He say's the part throttle feature came out in like '76. So he's thinking someone has placed a different valve body in this trans. Tranny is from an '89 dakota that supposedly only had 78K miles on it. Hard to believe someone would have swapped out valve body's , but who knows.
Anyway, he walked me through some other changes i'd have to make to the tfod install. But bottom line is I will not have part throttle kickdown. A feature I like on my current 904.
He said he didnt think I could just add the pt body, i'd probably just have to buy a complete new valve body that has PT.
