<div> <font size="3">You didn't mention what the vehicle is but most manual transmissions have a layshaft that is down in the oil at the bottom transmission. As long as that layshaft is turning it will be splashing oil and keeping everything lubricated. That layshaft is driven by the input shaft. As long as the engine is running (even at idle) the you will get sufficient lubrication regardless whether the driveshaft is turning or not.</font></div>

</font></div>
<div><font size="3">Flat towing is a whole other animal. Typically, the engine is not running in which case the main shaft is turning, driven by the drive shaft, but the layshaft is not. No splash oiling and the bushings can run dry causing damage. But if the engine is idling and the clutch is engaged - no worries.</font></div>

<div><font size="3">I suspect that the laws regarding coasting in neutral date back to the 30's when brakes were iffy at best. In today's world brakes are much more effective and have a level or redundancy built in. My daily driver has a small engine and provides precious little compression braking. If my brakes were to fail completely (including my hand brake) the engine braking would do very little to prevent a collision.<br>

Subject: [Shop-talk] Coast in Neutral -the next great debate<br>
<br>
<div id="yiv9265902714"><font size="2" face="sans-serif">I'm putting this out to the group to get
some opinions from the real experts here.</font>
<br>
<br>
<font size="2" face="sans-serif">If you put a manually car or truck in
neutral and release the clutch while going down long hills or coming to
a stop at a intersection, are you doing any damage?</font>
<br>
<br>
<font size="2" face="sans-serif">I'm not worried about fuel savings,
just is coasting in neutral with the clutch release.</font>
<br>
<br>
<font size="2" face="sans-serif">Any thoughts?</font>
