well my transmission (700r4) was about the only thing not leaking on my truck.

Now just yesterday i noticed redish fluid all over the pan.

Seems to be coming from around the tc , and then i noticed while idling the flywheel is kinda out of round or warped? I dont even have the flywheel cover so its always exposed and i just noticed how it going in and out like a bent rim on the axle. maybe 1/4 or so either direction?

Im thinking this may have something to do with the input seal leaking now?

What would cause the flywheel to do that in the first place?

you could ahve a hole in your TC it can happen a bad seal or a in case of all this a bent flywheel doubt it though. i would say your front seal or the TC

oh, tranny and tc have 5000 miles on them

could have a bum TC, take off the bottom plate on the bell houseing and takea flash light and look up and around a nice line around the TC on the bell housing means a leak
