T90A Fill Hole Or Drain Hole??

    My T90A has 2 plugs on the driver side, one lower than the other. The top one is high up, then the second is lower. The manual describes both as fill plugs…which one is supposed to be the fill plug? I don't really see a drain plug like on the transfer case… I know I should just fill up until it starts to come out the fill hole, but which one and tranny first then Tcase??

    Thanks,,

    The upper is the fill plug and the lower is the drain plug.

    The T-90 full level will bleed over into the transferr case so make sure both are full.

    filled up Transmission using top hole, a tight fitting plastic hose, when I removed hose, oil spilled out. I put the plug back in, checked the Tcase, oil oozed out of the fill plug..I think I am good now..
    Thanks
