This is the gearbox that came with the 200tdi engine I bought to replace the 2.25 petrol lump in the Series. I decided to fit the new engine to my standard Series box rather than this LT77 as the transfer box does not have selectable 4 wheel drive so would be running the front axle full time – the series axles have UJs rather than the Defenders CV joints and so are not designed to run on tarmac – as a result running a Series on tarmac in 4×4 can result in transmission ‘wind up’. You could get round it by fitting a Series 3  Stage 1 V8 front axle (which had CV joints), but these can be hard to get hold of. I’m also keen to get the best MPG possible from the Series and full time four wheel drive will not help.

However it was a nice low mileage box and I sold it to a guy who needed the short Defender LT77 bellhousing to go in his trialler.
