Transmission Noise/Chirp

I have heard a chirp between shifts since I bought the ED. I had the timing cover oil leak repaired under warranty a few weeks ago and decided to replace the transmission filter while it was in the shop. The truck had about 85K on it at the time. I occasionally tow a 22-foot dovetail car equipment trailer with a tractor or car on it. I saw and rubbed my finger on the inside of the pan. It was not bad—typical graphite lube-like shavings on the magnets, but nothing to be concerned with. I have changed and seen inside several other pans on other makes. They all looked very similar. Since I have replaced the pan/filter assembly, along with the eight quarts of transmission fluid the change called for, I have not heard the chirping as the transmission shifts. I do not know if it was a restriction in the filter, the oil itself, or maybe it was low. I really do not know. I do know when I mentioned it to the service writer; naturally, he had never heard of any transmission noises. Obviously, we can trust him since he works for the dealership! LMAO
