JST Posted June 26, 2008 Share Posted June 26, 2008 if reverse is top left then its an LT77 - which is what your truck would of had originally it would also of had an LT230 with 1.4 gear ratio assuming is was always a Tdi Quote Link to comment Share on other sites More sharing options...
GBMUD Posted June 26, 2008 Share Posted June 26, 2008 When they started making Tdis in 1991 they changed to LT77S and started using the 'Defender' name. There is not much to choose between an older LT77 and an LT77S. From 1995 when the 300Tdi came out they used R380 which continued through Td5 until they started putting the Ford engine and 6 speed gearbox in.

All factory built 200Tdi Defenders have the LT77S mainbox & the LT230 transfer box 1.410:1 [high range] low range is common across the LR Defender range of vehicles.

BogMonster Posted June 27, 2008 Share Posted June 27, 2008 AFAIK the LT77S had better (!) syncros on 1st and 2nd to remove the crunch on the 1-2 change. Except that it didn't. So maybe the S stands for Sod all difference. Quote Link to comment Share on other sites More sharing options...
forkrentfitter Posted June 29, 2008 Share Posted June 29, 2008 ther will be a label on your transferbox stating the ratio,you might have to clean the box to find it! if the box is in good nick the 77s is a better box than the original 77.
