Coasting with a Manual Trans

The Owners Manual says that to tow a Jeep with a manual transmission, you should leave it in gear and put the transfer case in neutral. Does anybody know why the transmission shouldn't also be in neutral?

I'm wondering how that translates to coasting during normal driving. There are three ways to coast (depress clutch and leave in gear, depress clutch and shift to neutral, or shift to neutral and release clutch) and I'm trying to figure out if any of them could be causing transmission damage. The OM specifically states not to coast in neutral with an automatic trans but doesn't say anything about the manuals.

Any thoughts?

Only thought I have is they dont call neutral the 'angel' gear for nothing... I have never coasted a vehicle not in a driving gear and never plan to.

As for towing, once the transfer case is in neutral the drive train is disconnected from the gearbox. I guess leaving the gearbox in gear makes sure the input shaft to the transfer case stays still?

I have been told from the mechanic at Camping World that its all about locking the tranny and engine together in gear so nothing moves while towing for a long distance and bouncing around. Costing in neutral for a few feet down the highway causes no problems at all to your vehicle. Made sense to me at the time so that's how I roll...

I just "coast" in the highest gear possible. I don't think coasting in neutral is the safest thing to do in most instances. I don't think the fraction of a gal. of gas you might save is worth it. Do what ever makes you feel comfortable. You're not going to hurt the trans.
