2004 bmw x5 3.0i e53 transmission.

I'm looking for serious help for my 04 bmw x5 3.0i e53. on a cold start it doesn't want to drive, i have to rev the engive at 4 to 5rpm for it to move an inch, but once the car fully warm up to operating temperature. the car drives fine with absolutely no problem, and no shifting issue. i read online the transmission fuild may be low i attemp to fill it up and this is what i found. fluid coming out of the fill plug like this (see pics). the transmission was recently service about a year ago with genuine bmw dexron VI.

i'm worried cause i love the car and don't really want to spend thousands to replace transmission or major repair
