Well, finally got around to doing the DR Mod, Hayden tranny cooler, and tranny flush. Took me two days and 12 qts of Mobil 1 ATF. Anyway, as I was checking ATF levels I seemed to have gotten it right after numerous tries.

I followed the method by checking levels when HOT as suggested in the STICKY. My level was right in the middle of the HOT range. "Awesome" I thought. I went back in, got a soda, and decided to check it one last time. WTF? Now it was reading a bit above the HOT range. Do take note that I had been driving around some so engine was hot and this was with my tranny cooler installed as per the FAQ. Hmmm. So now what? Do I need to drain it some or will it be okay?

On a side note, I decided to my engine oil level and was shocked to learn that it too was way over. Granted my engine was hot so I guess I'll check again when it cools. I know I only put <4.5 qts of oil.

 

for the engine when its hot it pours oil down out of top of engine down onto dip stick. or at least thats how i understand it

 

okay that makes sense... now about the tranny, anyone else wanna chime in?

edit: yup, checked the oil level when engine cooled down and it was normal, heh.

 

bump, still need the atf ? answered

 

ive always heard it can cause air to be entrained and affect clutch operating pressures and shift quality. some have mentioned foaming of the fluid but i believe that where it was severely overfilled. in some makes, the fsm states to overfill but ive never heard of that practice with nissan.

 

I would think overfilling would cause higher fluid pressures, which may wear down the pump and/or seals that are exposed to the higher pressure. Not 100% sure on that, just a guess.
