If this is your LT230, I'm going to say it looks like an LT230Q - 1.211:1 gearing. The input and high range gears on the intermediate cluster look too thick to be the 1.003:1 ones.

Is indeed - interesting... It must have been swapped out

Perhaps I'll find a disco box and strap a turbo on her down the line for the highways

1.003 3speed auto ,- 1.192 early v8 rrc --,1.410 Def,- 1.211 Disco A few other rare ones but think these are the common ones

There is some discussion on the issue.

The 36D (and higher) 1.211 late Disco 1 box do not handle the 4BD1 very well because of the tooth size.

You are probably better looking for an earlier 28D 1.222 box from an early D1/RRc R380 V8 or 29D & 32D Defender 90. They are not the "Quiet" box but are stronger. (AFAIK Not cross drilled)

The 1.003 (14D & 26D) were fitted to the 1983-1985 RRc with TF727 3 speed auto, They may also have made a later RRc appearance in the early 1990s (26D). (AFAIK the 1.003 are not cross drilled.)

Isuzu County's with LT85 and Lt230 were 1.003 as well.

Afaik the 1.003 was only fitted to auto rrc 83-85 with TF727 , and no V8 lr was fitted with a 1.4 tc.

Your serial no. Will tell you what ratio you had first 3 figures ...36d .1:1211..14d ..1:1003. ....I've got 1.211 which I think is a little low
