I have a fairy O/D (and 1786) and though mine does not slip out of gear when stopped, I have always treated it as a 5th gear and see very little need to use it otherwise. There are parts available on ebay from time to time and though the O/Ds are loud and can have issues, they do give a better 100km/h cruise which helps the 186 regarding revs.

I still have concerns about the main gearbox slipping out of gear on overrun what does anybody out there think, is my gearbox in need of a rebuild? Is there any Nissan five speed gearbox conversions out there? I have been told standard gearbox is a little weak behind Holden motor. Ta Eddie S :).
On a loosely related matter, my 109" has recently started giving me curry (or should I say is just playing up more than it usually does?) after a vigorous outing that included some muddy water crossings. I don't know if that's the cause, but I can't think of anything else.
Every time I depress the clutch I hear a slight grinding noise. When I let it go it's fine. I keep my shifts short and sharp for the time being but I'm worried about long term damage. I told my mechanic about it when it was there recently and it camer back exactly the same. Either they thought it wasn't an issue or they just paid it off. Anyway, I suspect there's muck in there and that the sound is from the thrust bearing. Am I right?
Any suggestions?
Rebuilding the overdrive is quite feasible. All parts are available from Rovers Down South in New Orleans, but be warned, parts are expensive, although the appreciation of the $A against the $US will have helped. Some bearings and seals are available locally from bearing suppliers, and this is probably cheaper.Quote:

Thanks to all your replies, I'm seriously thinking about a high ratio T/F case if I have to pull the whole gearbox assembly. Been in contact with Land Vesicle Spares who suggested this would work great behind the 186 Holden. I'm still worried about that standard gearbox would the HR T/F case stress the box more? Also been in contact wirh Dellow automotive yep no one his anything readily available for Series landy 5speed conversion. Eddie S

I've also got an Ashcroft 5 speed LT77 to Series Transfer case, but have yet to put it in a vehicle.
Thanks mate, the 5 speed LT77 is the one I would be interested in would that fit behind my 186 the adapter plate that goes to the original six cylinder 4 speed? And $700 all up included shipping to Australia? thats a great price for HRT/F case, most are asking around the $2000 for complete mod here in Australia. :)Quote:

If it was originally a 6cyl you'll need to get a 4cyl adapter plate fitted to the 186 first to fit the LT77. The LT77 has the same bellhousing pattern as a 4cyl Series.Quote:
