Transmission low on Fluid No leaks

Hi I checked my Transmission Fluid the other day to find it not registering on the dip stick. I looked to see if there are any leaks but found none. I put in 1.5 liters of fluid and had it registering on dipstick. Checked a few days later and again does not register on stick and I have no leaks. I am very puzzled . I also notice that at 100km/hr the truck seems to vibrate like the wheels are unbalanced. I think the transmission might be on the way out. Any suggestions.

The truck is a 1998 F150 4x4 with a 5.4 liter engine. I have added an additional 3 liters and appears it has disappeared as well. It looks like the filler tube is rotted. Could it leak out there and then get burnt off with the exhaust. I was also told it could be going into the transfer case if a seal is blown between tranny and transfercase. I am at a loss, i have checked the coolant and it does not appear to be in the radiator. Thanks for the help

Remove the transfer case fill plug and let it drain to see how much it is over filled.

Transmissions have vents I think. Perhaps it is blowing out during operation.
