I was told that my MAF sensor was contaminated and it needs to be clean (decontaminated) the part will cost $16.86 and the labor is $100.00. The mechanic advised that this needs to completed ASAP. I told him I can not afford the service right now and he told me that this may cause me to loose my warrantee coverage on my transmission? This sounds kind of fishy, labor at 100.00 dollars??

100$ is a little high for a 10 min job but hey they have shop overhead cost. You can change it yourself though, it is very simple.
As far as you loosing the transmission warranty, that I am not sure about.
