You don't put ATF in the front (transfer case) and rear diffs. You put gear oil in. Diaqueen LSD Fluid - 3775610

For the ACD and AYC pumps you use Diamond ATF SP III - ACH1ZC1X05

I'm surprised you haven't ruined the diffs yet.

Here is a handy list you can reference:

5 SPEED
- Gear Oil API classification GL-4 SEA 75W-85 or 75W-90
- Diaqueen M/T Fluid - MZ313376 (1gal)

Transfer Case
- Mitsubishi Limited Slip Differential Oil (LSD) or equivalent
- Diaqueen LSD Fluid - 3775610 (1 gal)

ACD Operating Fluid
- Diamond ATF SP III - ACH1ZC1X05 (1 qt)

Rear Differential
- Mitsubishi Limited Slip Differential Oil (LSD) or equivalent
- Diaqueen LSD Fluid - 3775610 (1 gal)

Mitsubishi Coolant
- MZ311986 (1 gal)

Mitsubishi Brake Fluid
- DOT 3
- MZ311987 (354 ml)

Mitsubishi Power Steering Fluid
- ACH1ZC1X04 (12 oz)

thanks. i realized that i wasnt supposed to put gear oil in. i drained the center diff and rear diff's atf circuits and refilled with the proper fluid. i still have the problem and that is why i am posting it up.
If you put ATF in the rear diff and front diff, you used the wrong fluid.

Are you talking about the actual diffs or the plastic reservoirs for the ACD and AYC? If you are talking about those, you actually need to bleed those systems as well.

restating that i did something wrong and possibly hurt/ruined the diffs is not actually helping with anything. the diff obviously isnt ruined because i have driven the car almost 5k miles since and have confirmed that all four wheels spin
Ok, have fun figuring it out.
