which trans?

Hello all. :newbie: I have a 1993 ford aerostar xl, 3.0 v6, 2wd. I think the tranny is goin out:frown:, it slips out of gear(mostly 1st but it'll do it in any gear), and won't go into 1st sometimes, till you give it some gas:banghead: It doesn't do it everytime, but it's becoming much more frequent. :swear:And it's not just when I 1st start it, I can drive it for 30 minutes, with no slip, then all of a sudden it slips outta gear, or I stop and it won't go into 1st. :angryfire

The trans fluid level is fine, and I had it changed recently. It was slipping before the change and did'nt get better or worse afterwards. Sounds like the tranny's going out, no?:1zhelp:
So I'm looking for transmissions, I know it's a A4LD,but there are several different tag ids:confused:, and I don't know:dunno:how to find out which I need. And what about using a tranny from different years?
:feedback:

Thanks for any info!:yugosmili

Did you change the trans filter???? I have a 89 that was doing the same thing untill I changed the filter.......A tranny from another year should work as longs as its for a 3.0l v6 :sunglasse

how many miles did it have on it. alot of transmission shops tell you that if it has been normally change and it has more then 100 k miles not to change it.i have an 93 aerostar and i had the tranny fuild changed and ended up blewing the modularor vavle on the side it and would slip in and out of gear when i wanted too. check your modulaor vavle frist
