HJ60 doesn't shift on 2nd gear from 3rd gear while vehicle is moving

Correction

Proven to reduce wear by up to 50%

There is NO gear linkage adjustment, nil, zero, zilch. Doesn't exist.


Nulon is Teflon and is friction reducing.
For a LSD to work, the friction plates have to be able to grip in order to drive the wheel with traction. same as for an auto box to have it's plates grip to provide torque transmission.
A Toyota LSD is usually not very effective anyway and after lots of Ks is as good as an open diff. Nulon will most likely make it more like an open diff as it will aid the reduction of friction and make an LSD into a no LSD.
The additive put in normal diff oil so it is suitable for and LSD is to make the oil film break down in sliding type action so the plates can grip. Nulon provides less ability to break down the film for gripping to occur.

In a gearbox with good synchros OK, with poor synchros ie second, Nulon won't help as the baulk ring in the synchro system will stay baulked because it cant grip the matching cone to synchronize the speeds of the two items.

the easiest way to check the clutch , is to put it into reverse .
as it is not synchromesh it will crunch excessively , if it won,t go in within a couple of seconds its a clutch related problem ,

Yes, that will check it out as it is the only ratio/gear which you actually change, 1,2,3,4,5th are not gearchanges at all.

That would be the first thing I would check. It was a problem when they were new and I must have fixed a dozen under warranty. The plastic seat breaks up and allows the gear lever to sink deeper into the box causing binding in the selecters.
