I've always heard that being towed with trans in N isn't good. I don't think electronic shift t-cases have neutral.
You heard right. If you have an automatic
DO NOT tow the vehicle in neutral. You'll be burning up the transmission in a hurry....... :doh:
If you had a manual-shift transfer case, you would put the transfer case in neutral and simply leave the transmission in
PARK. Since you have ESOF and no neutral position, simply leave the transfer case in 2wd and pull the rear driveshaft from the differential (4 bolts is all) then wire the driveshaft up and out of the way.
The reason it works that way....
The transfer case pump is located on the rear driveshaft output so as long as you are towing the vehicle in a forward direction, the transfer case will continue to be lubricated as normal. Pulling it backwards will not have that effect however.....
The transmission has NO pump action while being towed (which is why you can't pull-start them....no pressure to apply any clutches). If you simply put the transmission in neutral, the output shaft will sit there and spin away with no additional lubrication short of what just happened to be there after the truck was last driven. Just having the transfer case in neutral does not guarantee that the transmission output shaft will not turn; having the transmission in PARK will. This leads us to the problem with trying to tow an ESOF truck with an automatic transmission. You can't put the transfer case in neutral, so you would either HAVE to tow with the transmission in neutral (bad idea) or remove the rear driveshaft and make sure the front axle drive system is disengaged.
