to nerys: i've had the neutral switch disabled in an aging Datsun once before, and was indeed able to move an extra mile to a better parking spot when I ran out of gas. I discovered I could get up to 35 mph using the starter and being in 5th gear!

to the Doc: if the engine is off, and you select a gear while rolling, normally nothing will happen because, without the hydraulic pressure coming off the pump which gets its energy from the engine, nothing can be engaged. However, beware of the lock up torque convertor trying to engage in such a situation. Bad things can happen if the spped is high enough and the computer send the signal to the convertor to lock up.

Otherwise, no harm no foul assuming the torque convertor remains unlocked. which is to say being in 2nd is safer than being in D with the engine off during a coast.
