I had them build me a transmission and convertor package.
The 904 did not shift right and the stall speed was way to tight.
It had a problem and they refunded my money.
I sent everything back and went with a dynamic transmission and convertor.
Frank lupo's dynamic transmission.
My buddy run's a ptc trans. and convertor and has had no problems.(nova)
I have used two dynamic convertors with no problems.
I think frank lupo knows mopars better then most shops.
GOOD LUCK8)
