trans problems

Ok this best forums i ever seen far cars so i think good place to get help...
I'm total backyard mechanic to poor to be able to aford a shop lol so here we go coming home on highway and car kicked down in passing gear without me doing it myself that was just start of it telling me something wrong .
Getting off highway was rather hairy car was kicking and bucking lucky i live close to highway got it home after it dieing many times now i can't even put it in gear it's acting like a stick that just got clutch dumped..
If i'm not wrong the 93 crown has a locking torque which isn't unlocking (again if i'm not wrong)..

error code that i'm getting 653--transmission control switch did not change states during KOER but i also get that code for KOEO
also code 632 which is same thing
So what i need to know should i cry now because i have to drop tranny and replace torque in the cold or is the switch bad?
Is switch on or in the trans?
Or can it sence it all electronic that something else like code 41 oxygen sensor or code 63 thottle position sensor (which some other codes i got) is effecting it..
