Hey everyone, today as I was driving home from work (on the PA Turnpike) i noticed my steering wheel starting to shake a little and an odd knocking noise, at first I thought maybe I had flat tire so I pulled over to check, nope. So I go off at the next exit to give it a better look without cars wizzing by at 75 mph.
The knocking does not happen if I am accelerating or braking semi-hard but if I am maintaining a speed then it does, the faster I'm going the faster the knocking.
Transmission fluid all over the place in the engine bay. But I pulled the dipstick and it didn't look low.

If anyone knows what might be wrong with it help would be greatly appreciated because I'm supposed to go up to visit my buddy at Bloomsberg this weekend but if I can't figure out what's wrong I won't be making the trip.
