I did my diff fluid change today. I only bought one bottle of mobil 1 75w90 gear oil and after i drained the oil for 5 or so minutes, put the drain bolt back, pumped the bottle of fluid in the fill hole, no excess came out at all 
. Im worried but not sure if it will cause problems. Ill prolly get another quart and pump more into it till excess leaks out? What you guys think?

Has any considered yet that the tech probably used pumping device with its own tank? He probably just put both bottles in there and started pumping away.
My mechanic uses one which is why I know. You poor the fluid of choice in the tank, pump a handle to create pressure, and fluid goes through a tube to the tranny.
I'm betting he didn't know how much he'd need and just poored in what he thought would cover it.
(btw, yes my mechanic thoroughly cleans the tank and the hoses before each new fluid is poored in. He really hated me for the LE-607 haha)

I just did the diff fluid change in my garage and even though I squeezed some fluid to sort of flush it (there was so much gunk on the mag drain bolt, amazing, never seen anything like that) and spilled a bit and still had a bit in the bottle, when I lowered the car, some still came out. Quite a lot actually. So honestly, I am befuddled as to how some of you can put in that much and have nothing roll back out. And I raised just the back half of the car, drained, cleaned, refilled, lowered with the fill bolt off, let excess drain, reached in to tighten bolt, raised car, torqued, cleaned, dropped car.

With the car being level like this, it is hard to put all 2 qts of fluid into the tranny and definately impossible to put 1.75 qts of fluid into the rear diff. Fluid would be oozing out of the diff before he even finished the first bottle.
Prolly done over 200 s2k dif changes...correct amount for the dif is slightly less than one quart. Don't think your slick by putting in more than recommended...you can blow seals and cook the dif.
Trans takes more than 1.5 qts, less than two.
