My tranny in my 91 laser(nt auto) took a crap on me lastnight, anyway, i have a 90 nt/auto tranny and plan to pull it out and swap it tomorrow. I believe they are the same, but not sure.

ok i got the 90 tranny in, had a few small issues, but i will share them so anybody else does this will know. one of the electrical connectors on the tranny is different, it only has one wire, i think it is for the kickdown servo, it has to be cut off the 91 tranny and soldered on the 90. and the last thing, you will have to use a 90 starter, they kick out a little farther than the 91. thats it, everythingh works fine.
