Thread: LT 230 behind LT85 Isuzu

it should have a sticker on the back face under the filler plug, will be 1.003:1 or sometimes 1.223:1.

Thanks Justin,
Unfortunately there is nothing there
The serial number is prefix 23D & according to the Ashcroft website, that doesn't exist !!

david, is it possibly a 28D? the stamping is sometimes a bit dodgy...if so it is a 1.223:1 discovery case.

G'day David, Im pretty sure mine is a 23D, which is 1.003:1. I'll check tonight and get back to you.

The Land Rover Australian handbook says it should be 1.003/3.198:1

My 1988 county trans assembly had a 1.211 from factory.

Darnit !! I was hoping it was a 1.223 - would have gone into my TD5..
