Neutral Gear, Neutral Transfer Case and 4 Wheel Low Lock
 
I've always been puzzled by the difference between Neutral Gear (gearshift in neutral) and having the Transfer Case in Neutral (4-wheel + 4-wheel high lock to engage Neutral).

How are they different? Don't they both disengage the drive from the engine? So if you tow the H3 in neutral Gear (gearshift in neutral), it will be harmful to the tranny?

The other thing that confuses me is how to engage the 4-Wheel Low Lock. The manual reads: "To shift into Four-Wheel-Low Lock, the ignition must be in ON and the vehicle must be stopped or moving less than 3 mph (5 km/h) with the transmission in NEUTRAL (N). The preferred method for shifting into Four-Wheel Low is to have your vehicle moving 1 to 2 mph (1.6 to 3.2 km/h). Press and release the Four-Wheel-Low Lock button."

This one really gets me in the manual: how can your vehicle be "moving 1-2 mph" when when your transmission is in neutral?

Say you are going 6 miles an hour and put your transmission in neutral. My H3 doesn't abruptly stop and I don't think yours will either.

i guess it would. the tranny output shaft would be turned by the transfer case.
seem like you actually put tranny in park,tc in neutral, when being towed huh.

[QUOTEhow can your vehicle be "moving 1-2 mph"][/QUOTE]

you r coasting, it must shift better in motion.

Hmm, thanks.

I guess I don't have the habit of switching the gear from 'D' to 'N' when in motion*– I always assumed that might be harmful to the transmission, but I could be wrong...

switching the gear from 'D' to 'N' when in motion
 
if a vehicle stalls for any reason when moving i can bump it to neutral,flip the switch,and be running again in a split second.
the book says,stop,shift to park,put on the e brake,(count to 10!),restart, put in drive,,,such bs!.
a long coast in neutral ,or drive is like being towed but only the guys in the hills need to worry!!
trannys are made to drive,not be driven,buy a little dont hurt
