funny noise HELP!!!!

[oxfordwhitemach]

so i just installed a pro 5.0 shifter yesterday and a php intake spacer today, and i just heard a weird white noise sound while the car is under load. is the shifter noisy? do i have an intake leak? would an intake leak be loud enough to hear inside with the air on? have i power-shifted one too many times and lost all of my tranny fluid on the highway? i parked on a clean part of my driveway so i can see if its puking fluid in the morning. until then, i would love it if someone would tell me that it is just shifter noise.
