Since the Raptor is a 4x4 the transmission does not directly connect to either front or rear drive shaft, the Transfer case does. The TSB that JD posted up is for the transmission pump which is located towards the front of the transmission; opposite side of the Transfer case/Driveshafts.
Vash, is it the rear drive shaft that had the leak? If so, at any time did your truck get a new drive shaft or greased slip yoke? If so then the fluid you see is probably residual, left over from when shaft was removed & replaced. If it hasn't been out and it has a leak, then your Transfer case output shaft seal is probably faulty.
You are absolutely correct, pirate air. I must've had a brain fart. Too used to 2wd I guess. I think I just saw the cherry red fluid and my mind immediately defaulted to transmission. Dropped off the truck at the dealership yesterday morning and they replaced the t-case output shaft seal. As always, thank you for the info and clarification.
After picking up the truck and driving it the short distance home I immediately went under it with the creeper and verified that the front of the driveshaft and yoke were dry.
My truck is a fairly recent build and I've been underneath it to verify that it does indeed have the latest "BC" driveshaft and yoke combo. No clunking so far with about 1800 miles on it. Knock on wood.
Now, I just need to check the t-case fluid level to make sure they topped it off. I can't see any reason why they wouldn't, but never hurts to double-check that kind of thing since it's so easy to do.
