I recently bought a dart and wondering about the 904 transmission in it. I'm pulling drivetrain so just want to know if this is a decent year 904 to build or not. Engine combo will probably be around 400 hp so nothing crazy. I figure it's a newer trans because it has a electronic plug where speedo goes not sure what year they went to that. The drivetrain has vibration in it when sitting there and rev it up. Looks like the right balancer on the LA 360 bit maybe it has wrong torque converter..mot much else it could be.
