Help...drained wrong fluid in my 1997 suburban
 

I feel like an idiot, when I went to change my oil I wasn't thinking and pulled the wrong plug.
I pulled the plug that is closer to the front(it looks like it has something to do with the 4-wheel drive)
The fluid had a darker tint like oil, I don't know what I drained.
Can somebody help, what did I drain and how do I put more in?
Thanks

did you mabye pull the plug for the dif? or the tranny they would be the 2 closeest things try cheacking your tranny fluid if its the front diff i would check that fluid as well i dont think much would have drained from that.

I think it was the dif, how do I check the fluid on that? I know it wasn't the tranny?
THANKS

you would have to take that plug out again and stick your little finger in the hole to see if you can feel any fluid. you fill it with 90 wheight fluid till you can feel it on you finger to the first knukle

Thanks, will it hurt anything to drive it w/o that topped off? As long as I dont use the 4 wheel drive?
Question: There is a upper and lower plug, do i pull the upper plug and feel?

dont drive it untill you check the fluid evin if you dont use 4x4 the parts are still moving in there. im not sure about an upper and lowwer plug but just find the highest plug and mesure from it.
