I recently bought a 98 Preleude shell. I took my JDM motor and rebuilt trans out of my 98 Prelude (accident) and put it into the 98 Shell. The trans and motor worked very well in my Lude but now when I start off in D4 (new Lude) the car starts to go then when it shifts it shifts hard and then I get the D4 blinking. When I come to a stop and start to drive again the car starts off in high gear. Any ideas??
