hi all i have a mv automatics 350kw auto box its not full manual and has done about 200ks , with the auto computer plugged in it shutters and engine cuts out at around 3000 revs for a few seconds then goes again, but unplugged it runs normal changes gear hard but other than that fine its a excellent box. Has anyone ever got there auto computer overhauled or does it sound like the speed sensor ? any ideas or has anyone had this problem before ? Thanks
