I count 2 people mention the ENGINE MAIN bearing. And a couple more, plus me, mention the TRANSMISSION MAIN/MAIN SHAFT BEARINGS BEARING/S. I'd sure like to know what it is. I've never heard that noise before.
Sorry, hadn't gotten that far in the comments. Speaking of not knowing what the noise is, none other than Dan Brewer has conversed with me a couple times this week and he's stumped, too! I'm about ready to yank the trans and discard it at this point.
