Infamous mini dipstick

[svfetter]

Just checking out the baby dipstick that so many are aware of on these newer expeditions. I removed the plug per instructions to access small plastic dipstick to check fluid level and fluid immediately began to run out.

Truck had been setting for several hours and all fluids were cold. Engine was not running. I know you are supposed to check with engine running. How can you check level when you can not remove plug without fluid leaking? Would it make that much difference in fluid level in the lower pan, not running vs running?

What am I missing?

when it isn't running and has sat a little wile the converter drains back into the pan that is why it should be checked hot wile running.

Really ? Then this trans is quite different than past ford models. Usually under cold conditions, fluid levels would show lower on the stick and then expand when heated.

Your missing my point, all automatic transmissions according to the manuals say check the fluid at operating temperature (hot) wile running. if you check it cold not running the fluid from the top half of the converter drains back into the pan. That is why you will have fluid pouring out. The fluid will expand some but a lot more comes out of the converter and the trans cooler when it is not being circulated by the pump when it is running. Ford should have put a regular dip stick on the trans.

I do understand what you are saying. I just find this a surprising circumstance or condition. I was actually trying to install a after market dip stick but decided to hold off until I learn more.
