Thanks for all the input guys. I had already drained and refilled the system before seeing the comment about the new washer. However, I am going to wait until the summer and do it again. I am just going for a hint of red in my fluid. Right now, it is black. So, if I have to drain and refill...
I have similar rattle sounds, but it only occurs when AC is on. It never happens otherwise. It's impossible to diagnose, because it will not happen in P when idling.
Thank you for the information.
I gotta wonder if I really need a new washer every time I remove the plug?
By the way, I'd give you a million bucks for a copy of that workshop manual, or could you at least point me in the right direction to obtaining one, especially a digital one?
Is there an advised torque for putting drain plug back in transmission pan? I can't find torque specs, although the owner's manual does go into detail in how to check the fluid levels.
I haven't removed it yet, just planning for a drain/fill procedure tomorrow after seeing the dark brown color...
