What trans in 1965 Barracuda with 273

Which transmission does it have.... If an automatic it's a 904. If it's a 4 speed it's an 833. If it's a 3 speed manual and the problem is the horrible grinding and clashing when you try to shift into 1st gear and the car is moving, don't worry about it. First gear in this transmission does not have any syncronizers, never did. With practice you'll get to the point where you can silently drop it into first around 5-10 MPH...
