Erratic shifting P0785 code. stuck in gear plz someone help me Sign In

first of all - 2004 Volvo S60 with a 2.5L Turbo 2 whl-dr 183,xxx miles... Hi, thank you for reading... my car drove great shifted fine, but once it warmed up (especially in park with car running) it would shift up and down extremely hard but only in 1st, 2nd and 3rd gear tho. It would NEVER having shifting problems in the higher gears. often it would go away after about 20 min of it constantly doing it. well about 30 min ago it started to do the hard shifting and all of a sudden the dash lit up with "service trans" light and also check engine. And now the car feels like its stuck in 3rd or 4th gear. It is very sluggish when driving from a stop (kinda like if it were a stick shift and I was trying to accelerate from a stop in 3rdgear). The car drives excellent once it gets up to a higher rpm. and also the little lcd window on the dash that says what gear i'm in just has a little " - " instead of a "D"... when I hooked up the OBD it gave P0785, P0700 and P2407 (which I already knew about)... So now I could really use some assistance, I have NO Idea what to do. I do all my own maintenance and repairs on all the cars ive owned, but have never ran into transmission problem in all my years..... ***the next day : Today I started the car up and its still giving the code and the check engine light is still on. The car is not stuck in high gear anymore, so I think maybe one of the solenoids was stuck open/closed and thats why it was stuck in high gear. I didn't drive it long enough for it to start shifting erratically.. So that is what is going on with the car. If anyone can plz help me identify or diagnose the problem at all, or maybe even give me a few steps as to how it can be fixed i would really appreciate it. this is my only transportation to work to support my family and I love this car.
