G'day All
I have been asked by a fella who has a 73 LJ 3sp/man one owner 115Ks that shudders in reverse gear.
He has replaced a lot of things including motor and gearbox mounts, re-surfaced the fly-wheel and a couple of other things.
He did say that not long after the car came out, there was a remedy for this situation to be circulated around the Holden dealers.
Has any one heard of this trouble and most importantly know how to fix it?
Thanks and kind regards............Barry.

Sounds familiar ,i had a LJ 3 on the colum and it did the same,could have been my bad driving though because it stopped after taking my foot completley of the clutch but i used to have to ride it a little to vary the speed thats when it used to shudder.

it is flex in the mecanical clutch setup that is causing the problem
to fix rebuild the rat trap.
the holden dealer remidy was a strenthaning kit that changed the angles
of the rat trap but you would be lucky to find one
the only one ive seen on ebay went for nearly 300 but i was lucky to find a nos one at a swap meet for 20 as the bloke didnt know what it was

Thanks fellas.
The fella with the problem was once a GMH mechanic but has since working a long time ago and had forgotten how to fix it.
I will give him a ring and let him know.
Much thanks..................Barry.

Did he replace the pressure plate and clutch plate? An obvious one I guess but has to be asked.

G'day surfmaster
As far as I know he has replaced the engine and gearbox mounts, new pressure plate, new clutch, uni's, re-surfaced the fly-wheel and something about a spigot (bearing) ?

G'Day Barry,
If all that stuff has been replaced it should work in theory without shudder. I will put my thinking cap on, but all I can come up with after that is oil on the clutch plate, but if the problem existed before the parts replaced then it must be something else. I will dig out my old mechanic books and have alook there?

Has he looked at rear suspension bushes?
Usually its related to the driver slipping the clutch..they don't realise how much they do it.
