Posted from 4g61t, but i need help like NOW so...
btw, i'm running a 1990 mitsu mirage with a 1990 gs-t engine and transmission swapped in.

Ok, so after FINALLY getting my car out of the service place I took it to to do the timing, oil filter assembly and exhaust, i cranked it up and everything was working fine. so i pulled out onto the main road and as soon as i got to my 2-3 shift, the car started sputtering and died. i pulled over and started it up again the same thing happened but with the 1-2 shift. so i started it again and then got it in first and it would only go to 2-3k rpms! and sounded like it had REALLY aggressive cams! no matter how far down i hit the gas, it stayed right there and when i let off the car died. so i try to start again and it wont go into 1st gear! it ground really badly so i tried to start it going in 2nd and slip it to get up to speed. that gear ground too! so now it won't go into any gear and it won't maintain idle. it'll rev up to 3k and then practically die and then rev to 3k again and if i hit the gas revving it a little it'll go back down and then die. i need to drive this car 2000 miles starting on tuesday and i need help PRONTO!!! thanks for any and all help and if you'd be willing to help me out with this thing, i'll freakin pay you, i don't care, i need this car done NOW! i've dropped it off at a shop so we'll see what they can do tomorrow, but since a lot of you are seasoned veterans of the quirks of these cars, i'm asking you first and i'll pull it out of the shop right away if you'd be willing to work on it or whatever. thanks again!

btw, i'm thinking it's just low tranny fluid for the lack of shifting into gears... but please let me know if i broke something or whatever.
