Hi I have a 99 cumming automatic and the tyranny just stopped responding it will go in to all gears and drive fine for about half a mile then stop but all gears work fine when it actually goes into gear I don't think I need a new tyranny cause it seems to shift fine when it will drive but something's wrong I'm not very mechanically inclined so I was wondering if anyone could help please and thankyou
