Gearbox/diff questions
I'm in the process of having a 6 speed conversion on my 2002 WRX, and have come across a few oddities!
The OE 5 speed gearbox code was TY754VN2AA - which is listed as a US box with 3.9 final drive however it is an EU/UK car?
The replacement box is a JDM 6 speed code TY856WB4KA which cam with a matching rear diff (3.9)
Here are the oddities!
APi confirmed that my box was a UK box therefore 3.354 ratio (due to drop gear I believe) so I had to use the supplied rear diff, this caused a further issue with the rear shafts not fitting as my rear diff was LSD and the supplied was a helical so needed different shafts, is the helical rear diff vastly inferior to the LSD?
My replacement box is listed on all the websites as a JDM box with DCCD however we cannot find the DCCD wiring plug? Also the person I bought it from also said it was not DCCD? Any ideas what might be going on?

The dccd connector is high up on the drivers side of the box on the rear casing, IF, it is dccd type

Cheers David - Thanks for sorting the Drive shafts for me!
Box is an odd one as the code (based on the online transmission charts) says it's a DCCD box but the point where the garage would expect the see the DCCD socket only has a blanking plug in it with no wiring, is this common?
