Trans makin ODD noises...
So I bought this truck in the summer with a host of transmission issues and ive slowly been making it better. Now I've some across something that google hasn't made clear.
When it's at like 30 degrees or below my transmission wails like chewbacca until it gets nice and warmed up. When it does this, it feels like that transmission is just taking a nap and there's huge power loss that can only be fixed by applying more throttle and gettin rpms up, which shuts up the noise for a little bit too. I can hear what sounds like air escaping from somewhere behind the cab during this as well and that noise stops when throttle is applied as well.
It has a reman E4OD in it now with about 170k miles on it, many of them towing miles. Fluid is red and doesn't smell burnt. All help appreciated, thanks!

You're describing the Exhaust BackPressure Valve. It closes off the exhaust just after the turbo. It's purpose is to reduce the airflow through the engine to assists with warmup. It's normal.

I'd imagine they burn to a crisp in the Arizona heat. One thing we all agree on, too much heat kills transmissions.
