You are going to want to lower the transmission to remove the clips that hold the lines in the transmission.
@coolasice was able to get his clips out using that method as well as putting the vehicle on 4 ramps/jacks to have a little more clearance to be able to lower the transmission.
It's a VERY tight space between the top of the transmission and the body of the vehicle. Unless you have smaller hands, you're probably going to have to lower the transmission.
I ended up just cutting my lines near the engine oil pan and using a compression fitting. I don't suggest doing what I did at all.
