Skanny Posted July 19, 2011 Share Posted July 19, 2011 Hi Folks, I have removed this gearbox and transfer box setup from a manual 2001 Discovery 2 Td5. I have never seen the bit circled in yellow before on any of the D2 Transfer boxes that we have removed. Its a 41D prefix box with Diff lock sliggot present. I notice it has fresh gasket sealer round the rear most casing on the box and also under thie raised circular casting on the top of the box. Any ideas??????

Skanny Posted July 19, 2011 Author Share Posted July 19, 2011 Ooooooh a rairity then! Interlock solonoid????? is that a kind of electronic engaging diff lock?

CwazyWabbit Posted July 19, 2011 Share Posted July 19, 2011 Apparently it does.... DISCOVERY GEARBOX INTERLOCK ASSEMBLY Discovery vehicles with automatic transmissions are equipped with a transfer gearbox interlock solenoid which prevents the driver from moving the transfer gearbox lever from high to low or from low to high unless the automatic transmission is in neutral. In any event, gear changes should always be made at less than 5 mph (7 kph). Shown below is the transfer gearbox interlock and related components used on Discoverys with automatic transmissions through 2003 model year. Beginning with the 2004 model year, the range select interlock solenoid is moved to the shift lever housing. .... I assume if you have a manual gear box you just have to .... remember Quote Link to comment Share on other sites More sharing options...
Skanny Posted July 19, 2011 Author Share Posted July 19, 2011 Im sure there are no wires coming from that end of things and i have seen hundreds of D2 transfer boxes , from early through to late, manuals and autos and I have never seen one like this before, the instant i saw it i thought 'what the hell is that!'

CwazyWabbit Posted July 19, 2011 Share Posted July 19, 2011 The wires may be under that black bracket, it may also have a neutral switch hidden under there. Have a look in this random Land Rover doc I found on the web http://file.seekpart.com/keywordpdf/2011/3/22/20113228267973.pdf I do wonder how a NAS or Japanese spec box ended up here though.

Skanny Posted July 21, 2011 Author Share Posted July 21, 2011 Thanks for the link, I too am at a loss as to how it ended up here. Maybe in the early days when the pound was stronger it may have been more cost effective to import a transfer box from the states than to by one locally?????

They all came from here in the first place. If the production line was running short of boxes for UK units and US spec ones were available they may well have transfered US units to UK units. Omitting to wire in the eletrics. Quote Link to comment Share on other sites More sharing options...

Hi guys I have an ex Japan disco and I've always put the auto box into neutral (cos the instruction manual tells ya too!) before moving the transfer lever. I can see that as I have some idle time tomorrow, some experimenting may be in order! Yay for weekends Cheers, James NZ Quote Link to comment Share on other sites More sharing options...
