sputtering missing flooding when in Drive

I recently had my TF999 automatic rebuilt, and now when I am in drive and accelerating, I have a bad miss, sputter, and flooding. It is not close to as bad if I shift it manually in 1st or 2nd, just when I leave it in Drive. I have the stock Carter with the nutter bypass. It did not have this issue before, but my tranny and tcase were just hanging on until I blew them up.

Any ideas where I should start? I already changed the plugs, rotor, dist cap, etc with no change.

This all happened after the tranny rebuild? hmmmm. Probably a coincidence. I's check the fuel pump pressure and output, change the fuel filter, and check the return line to the tank.

First thing that I would do is toss the Carter out on the highway in front of a semi! Seriously though, I agree with Missouri that this sounds like more of a coincidence. There are a lot of threads on here about what to look for on the BBD. Check the fuel pressure and look to see if you have gas dripping in the carb. The sputter and flooding could be plugged venturi or a bad float. If you can find a Weber or Motorcraft 2100/2150 on craigslist or ebay, I'd snatch it up and change over the carb. I find the Weber easy to adjust and running the 38DGES on a stock motor I'm getting 17mpg with 31" tires.
