Either way it's a rebuild. Glad I bought an aftermarket warranty.

If fault code P2704 then most likely your VIN is in the range listed in LTB00514 that affects vehicles (all LR and other makes) from a particular VIN in MY08 through MY11 due to stator bush material being changed from bronze to white-metal (a lead-free improvement!) which doesn't last, although very frequent oil changes seems to prevent the wear. The worn stator bushes prevent adequate oil pressure for clutch E but old oil must be thicker (perhaps with metal) than new oil because the fault regularly occurs soon after an oil change. When my D4's box failed early last year ZF Australia were offering a complete rebuild for far less money ($3950+GST) than independent rebuilders quoted. Fault code P2704 can only be caused by the worn bushes but other fault codes may also be recorded.
