Transmission code P1768

My car Has a type S transmission. I was told my transmission is shot just by someone checking the fluid in it and the fact that the catalytic converter would go over like a two inch hump into his shop. The car still drives. D5 light was blinking but is out now. I do not drive it in d5 never did I always drive it in d4. But it started one night a couple weeks ago I was coming from work and pulled out the gas station kind of up a hill the car stalled n the middle of the road and jerked hard. I was like three miles from home and as I was trying to pull in the driveway the car would not accelerate enough to go up the driveway. The car does fine in reverse and driving. It used to jerk when changing gears but all that stopped when the car jerked real bad that night. The problem is when you come to a stop getting the car to go is hard. You have to push the gas hard and it barely goes but once its going it is fine. I went and had it hooked up only code was the clutch control pressure solenoid valve code P1768. Would that make the car do what it is doing and the d5 light go out?
