Digital Posted August 29, 2010 Share Posted August 29, 2010 Hi guys. Can someone tell me if the J-spec TwinTurbo auto diff is 100% the same as an UK/US/EU-spec TwinTurbo auto diff? Quote Link to comment Share on other sites More sharing options...

Homer Posted August 30, 2010 Share Posted August 30, 2010 Almost 100% certain it's the same provided before/after are both LSD variants. The ratios are for sure. Quote Link to comment Share on other sites More sharing options...

Homer Posted August 30, 2010 Share Posted August 30, 2010 Uk spec has an oil cooler dont it? other than that they are the same. Think that's only on the 6spd, never had a look at a UK auto diff. Will check the service manual, brb.. EDIT: Can't make sense of the service manual, it shows the "large" casing diff for "Europe and GCC Countries" and the small casing for "other countries". Confused now! Quote Link to comment Share on other sites More sharing options...
