Are all 100 series Std Gearboxes the same ?

Its fairly normal for there to be many differences between a petrol and diesel of the same model other than just the engine.

I don't know enough to advise - but if you post the question on LCOOL (Landcruiser owners on line) you will find there is a wealth on knowledge.

The gearbox is different. The 100 series which came standard with the 1HZ (non turbo) diesel had a gearbox that had the model number R151F.
The petrol and 1HD-FTE (turbo diesel) had the H150 series gearboxes. Much more heavy duty.
From memory the petrol had a H150F and the turbo diesel a H151F. As far as I can remember the only major difference between these 2 is the 1st and 2nd gear ratios.

Those gearboxes are normally pretty tough.
are you sure its not your clutch making the chatter.

The standard 1hz powered 100 series has a relatively light duty gearbox compared to the petrol and turbo models and are a known failure point. A friend replaced his twice within a few years due to towing duties flogging it out. The third time he fitted the petrol/turbo box which is a heavier duty unit as was mentioned in an earlier post.

Pop's onto it,
but you really need to state exactly what model Landcruiser you have too avoid confusion and help others help you.
I'm having a guess that you have a HZJ-105 .
Is the petrol model V8 or straight 6 i.e. 100 series or 105 series,
when you say std. do you mean base model or not modified?
The "R" and "H" boxes are different where they fit onto the transfer case,
I think you can replace the relevant shaft/gear, but would be easier to get the transfer that's on the transmission.
Also the clutch shaft and splines are different but can be sorted.
