The shift pattern on this 15 spd will mess me up for the first few miles when I jump in my Charger. Comes back quickly though.
The OD are a little different the drop from first to second is big. Downshifting to first you have to match the RPM to road speed to get it in smoothly.
Mine really lugs at 50 mph I just put it back in 3rd /direct.
The A833 OD is not the best choice for street and strip, but makes a great cruiser.
