Velvet Drive chatter in neutral
Does anyone have any experience with these Borg Warner gears?
Any help would be appreciated.
Thanks

Re: Velvet Drive chatter in neutral
Fluid looks clean and clear dextron. No noise in either forward or reverse, just neutral?

I am still leaning toward an engine related issue rather than a tranny one. Will the tranny rattle as you increase rpm in neutral? When was the last time the engines were serviced, a tune-up done, etc.? Does the engine hunt at idle by any chance (rpm up and down)? Have you started her up cold or was she warmed up just before you arrived for the sea trial (old trick)? A tip to potential purchasers; tell the seller prior to the sea trial date that you do not want them to warm up the engines prior to your arrival. Then for assurance, as soon as you get on board, feel the engines to ensure they are not warm prior to starting them. If they ignored your request and you find them warm anyway, walk away and book another sea trial date with a warning not to warm them up again next time. They may be trying to hide something.
Along with the TPS noted above, IACs cause idle issues also, sometimes undetectable by ear. The little idle air filters in these are also know to cause problems (if it's even there anymore). I'd get a tech to hook up Merc's diagnostic software to see if it pulls any useful info including stored faults. While there, they can perform a couple of tests including a cylinder drop test.
This could be anything from something as simple as a little filter to something more complex like an injector or worse. It's not impossible for it to be a tranny issue but chances are it's not. In any case, you must rule out the engine first.

Re: Velvet Drive chatter in neutral
By the way, are you sure it's the tranny rattling and not the engine's flex plate? It's an easy oversight because of their proximity to each other.
