Help with tranny

[Buschboxer]

I am about to bite the bullet and by a tranny. While driving it feels like the brakes are stuck, I have backed them off, so I know that is not it. I have adjusted the throttle pressure and flushed the fluid, but it has no power. I can throw it into neutral and the engine will rev up perfect, but it isn't transfering the power while in drive. It will drive, but it struggles to get to 55 mph. Do I just spend the money on a tranny in it or is there something else I can check? HELP!!!!!

Haven't had it out to do much, cause I didn't want to do any damage. Did a tune up about 200 miles ago. Does it sound like an engine problem???????

YUP, had this *exact* same problem with MY aod, the one in my 88'. The engine is fine, it revs to the moon but it doesn't move the freaking truck a damn foot when it's doing so. It revs's about 3K and I'm run down the street at about 7mph, my neighbors just LOVE it when I do this. If I"m willing to chance things my trrany WILL shift into 2nd but only after I get it up to about 20mph and then it SLAMS into second hard enough to knock small children out of the back. Near as I can tell first is just blown and every now & then I'm able to kick it into second but the shift is pretty freaking violent. THIS is why I parked it and it's also why I have a boneyard AOD sitting here on the tranny jack ready to go in over the next few days.

To answer your specific quetions, if you've *already* ck'd & adjusted the throttle pressure then there isn't a lot more you can do, the problem is more serious than that. Either pull it & have a bench rebuild done or swap it out for a rebuilt unit. One or the other, There just isn't a lot of middle ground to be had.
