As Flash said, tranny dipstick is too long and hits bottom of pan in stock configuration.
Solution: Either cut about 3/8 off the end of the dipstick or a simple solution is to take a pair of pliers and bend a lazy "Z" in the dipstick to make is a little shorter...
Do not worry about having a little to much ATF+4 in the transmission; these transmissions like and do much better having a little extra ATF in them!!! Like a 1/2 to 1 Qt. extra...
Something like this:
