looking on the bachmann site, in the parts department, for the HO DD40AX.  not seeing it . . . .  have i gone blind ?

so . . . does anyone know if the body shell on the Bachmann HO Alco FA2 Diesel Loco DCC SoundTraxx Equipped is interchangable with the Bachmann HO Diesel FT-A with DCC.

Hi.  Just got into this a month ago. Bought the digital commander, got addicted and then bought a mile of track, 5 locos 20 rolling stock, bla bla bla  all exclusively bachmann and all HO. . .  almost all from my lhs.  i try to keep him in business . . . loving this therapy while i wait for warmer weather to fly my rc plane/heli collection.  question:

the emd ft-a dcc that came with the digital commander doesn't appear to operate at full power, its as if it gets to 75% and that's it . . .and it exhibits unusual behavior, as if it spontaneously loses grip of the track (like its bottoming out, though its not . . . motor pitch remains constant 75%).  this will happen for a few seconds, and then its fine. . . .and it happens under all imaginable circumstances . . .dcc, dc, straight, curved, forward backward, body on/off, trucks adjusted/re-adjusted, trucks removed/reinstalled, drive shafts uninstalled/re-seated re-installed, truck bottom housing on/off . . . . . (i have 2 other new ft-a's and 1 b from you, all perfect, and i have ripped them apart to see why ther work so well . . . no conclusions)

i am new to trains, but not new to the hobby world . . . so i have no fear of noodling around with things . . . . in fact i bought your silverton/durango and out of the box the 2-8-0 failed to run smoothly . . . i diagnosed it with messed up wheel linkage, and i could have sent it back, but didn't want to wait, so i ordered the entire chassis from your parts site, installed is (like doing surgery on a grasshopper).  had to swap out the little circuit board in the wheel housing for the original, for some reason the part that came in the new chassis was not happy with the fact that i had installed the 8-pin dcc chip, or just wasn't happy . . . i then soldered in a sound decoder, found a lovely home for the speaker in the tender, and wow, this is 1 smooth running happy train . . . . .
anyway, back to the emd-ft-a . . .please advise
