edwardsbob Posted April 2, 2009 Share Posted April 2, 2009 Hi Guys - some general advise please....I have a 1500 with a fairly standard set up of non overdrive and as far as I know whatever the standard diff was put into it - all seems pretty normal...However there are times when I yearn for the luxury of that last gear. I've read lots from you all about swapping for an overdrive box (I noticed that theres one on ebay at the moment advertised as having 'everything' necessary for the swap...) but and here finally is my query - do I have to change the diff as well?Please advise (and apologies if there are threads everywhere talking about it...)Bob Link to comment Share on other sites More sharing options...
Nick Jones Posted April 2, 2009 Share Posted April 2, 2009 Overdrive is very nice to have and makes the car so much more relaxed at speed.Obviously there is some risk attached to buying parts from ebay (may be knackered/incomplete etc) but full conversion kits with new/reconditioned parts from the Triumphs specialists are pretty expensive these days.You do not need to change the diff - they are identical on OD and non-OD Spit 1500s.You could also consider a 5 speed conversion using a Ford Type 9 from a Sierra.CheersNick Link to comment Share on other sites More sharing options...
CharlieB Posted April 2, 2009 Share Posted April 2, 2009 No, the 1500 had a 3.63 diff whether fitted with O/D or not. You will need a new propshaft though & a few other bits. Link to comment Share on other sites More sharing options...
edwardsbob Posted April 2, 2009 Author Share Posted April 2, 2009 Thanks both, thats one query answered. When you say the gearbox in a sierra fits how about an old mondeo? I've got one of those sat in the yard about to head for China???Bob Link to comment Share on other sites More sharing options...

edwardsbob Posted April 2, 2009 Author Share Posted April 2, 2009 Just having a quick scout around for them - does it matter what sized engine they come off? And are there other 'necessaries' to be able to fit them?....Bob Link to comment Share on other sites More sharing options...

Jason Posted April 3, 2009 Share Posted April 3, 2009 There are now an increasing number of people selling Type 9 kits and parts - shop around, a simple "type 9" search showed up this http://www.canleyclassics.com/partfinder.asp?partnumber=type%209 personally I like to keep it broadly Triumph and I do like an overdrive but each to his own and the Type 9 box is pretty strong Link to comment Share on other sites More sharing options...
