2005 Saturn Relay Trans and power steering problems

Hi. I would like to know what kind of problem my transmission has. When I stop the car and start to accelerate, it FEELS like the car is being rear ended (its not). I am guessing it is a transmission problem. I got the flush last month. I’m going to take it to the Transmission shop, but would like to know beforehand what kind of possibilities there are.

Also my power steering fluid is leaking. It seems to be dripping off the belt and splashing everywhere. I am pretty sure that I need the pump replaced. Does anybody have any idea around the labor cost of this repair? The pump costs about 50 dollars.

I appreciate anybody responding!
