[C38] Transmission shifting vs. RPM

I used a pump operated by a battery operated drill.  Worked like a 
champ.  Be a little careful pumping ATF back in as it can be under such 
pressure that it will blow off the small plastic tube from the coupling.

I tried to change the oil with the same pump but the dip stick hole is 
to small to get the tube down it.  Any recommendations?  maybe take the 
dip stick rod off the block and pump directly from there?
