This generates heat very quickly. Over many times of coasting (in neutral), gears on mainshaft, and needle bearings (inside of mainshaft gears) gauld or weld themselves together. I recall one manual trans. that welded the mainshaft pilot (needle brg's.) to the mainshaft. I have rebuilt & repaired many manual transmissions. Again, coasting (in neutral) or towing, without unhooking the driveshaft--equates into "MAJOR" damages."
