Subject: Loud whine from gearbox on overrun?

Chaps, the gearbox in my 16/80 recently started making a loud whine when easing off the throttle. It sounds as it always has done when accelerating or under power but the instant I lift off or coast it whines. It has certainly become loud enough for me think it’s not normal.

Any thoughts on what may be causing this?

Thanks Rich...

I would start by checking the propshaft.
Recently replaced the prop on my 2 Litre with a new item with modern Hardy Spicer universal joints. The car is certainly quieter and an annoying vibration has disappeared.
Best regards

Thanks Mark, that's on the list of jobs, it's just that today it became more noticeable...

and of course, you've checked the oil levels in the 'box and axle...

Hi Richard,

Jumping across from the facebook page, can you look whether your manual box replacement for the ENV 110 is a "Z" or and "OH" box? They both fit but I would like to see pictures of your chassis as well

If you lift the floor and take a photo which you can post on this or the Facebook site, I can tell you which one you have. If it is an OH box it might be the layshaft bearings which I replaced on my box.

Hi Colin, it's a Z Type box, I've put some pictures on the Lagonda FB page. Cheers Rich...
