I believe I have a bad torque converter because the car slips gears driving forward. It also cuts out if just placed into drive when cold and jerks forward. If I press the gas flat out it does not move from the first gear unless I take my foot off the gas slightly. The main problem I have is when placed in reverse gear the car does not move at all (not even on a level road). What can be the cause of that? I am struggling and not sure if I need a whole new transmission!
