transmission service light

there is a transmission service light that comes on everytime i drive the car. When this happens i lose my three different diff modes.
the problem occurred after i did a clutch swap on my own. I mistakenly put the wrong fluid into the center diff. a used the gear oil instead of atf. i quickly realized my mistake and drained the center and rear diffs and put in the correct fluid.
the light comes on after i drive my car for a hundred yards or so. sometimes i can get a 1/4 mile, sometimes not even out of my driveway. also, if i start the car up and let it warm up, then rev the engine some (as in showing my friends a new mod or something) the lights pop on. it goes away if i restart the car. but comes back when i start driving again.

I am planning on draining the diffs again because there might be some residual gear oil. i thought it could be a wheel speed sensor for a while, but the abs light would also come on. so i know it is just transmission related. any help you guys can offer is great. i am over 36k so the dealer wants to charge me to look at the car

ive tried pulling the codes with a scanner from autozone/o'reillys. there arent any. if it was a wheel speed sensor the abs wouldnt work and its warning light would be on too right?

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. 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
