ok

the lt95s are all the same. ( not counting the 101)

first gear to forth gear are the same.

what is different is

looking at the back of the gear box, you see the housing round at the top which unbolts. and at the bottom you see the aluminum housing just behind the hand brake drum. 1/2 way between the two you can see 1/2 a shaft. that's 1//2 on an angle from the output shaft and the round housing at the top.

between these of inside is 3 gears. 1 on the back of the gearbox. one in the middle and one on the bottom whose center lines up with the output shaft/ drive shafts.

it is these 3 gears that control the final drive ratio. thus affect all gears

the top gear is on the back of the gear box, the middle or intermediate gear and the bottom gear is in the transfer case. IE it is like a crown wheel on a differential only the teath are on the outside.

it is these gears that are different between the higher revving V8 range rover and the lower revving Isuzu. in our case the gears are .996. though the disco and defender range of transmissions etc there are a number of different ratios, which you can play around with. but leave that to the guys with 35" rubber and 5 speed gear box's

But that is because they have relatively high diff ratios so need a similarly low ratio for the transfer to compensate.
