Default gear E40D

IF all wiring is cut from the E4OD from what I have read it will go to high pressure and go to the default no power gear to get to a shop.

Now dose anyone know what the default gear is for an E40D?

From what I see in the the E4OD Reference Manual diagrams it should be 4 gear (OD) but I may not be thinking right on this one.
I would be guessing 2nd gear but the diagrams show ON & ON for the solenoids in 2nd gear.

Does ON mean no power to the solenoids?
It also shows ON means the oil will flow through the shift solenoid.

I was reading about the no power to the transmission in the following writeup about LIMP mode:
AutoTrans Articles - What is Limp Mode?

Thanks

When all electrical connectors are removed from an E4OD or 4R100 you will have 2nd gear in manual 2 shift position and 4th or OD in drive position. Reverse will also work.

What he said ^.

When the manual says a solenoid is ON, that means it is powered. Off is non-powered. The pressure control solenoid (EPC) defaults to maximum pressure with no electrical power.
