My problem has to do with a manual transmission type auto ( A 1991 Infinity G20). Anyways it happened when i was in the freeway going up hill so i tried to downshift to 4th to get more power and then i don't know what happened but the whole shifting lever/stick just broke or something or popped out of place. It's still driveable but the shifts are all messed up and its harder to switch gears. So how do i fix that problem myself or can i?
