Yes, that's the same drain conversion. I fitted the kit to my D4 although it took considerably longer, at least partly due to the dirt that kept falling on my face. However for the 4.4 a hole has to be drilled in the side of the sump to take the drain - a semi-formed hole has to be drilled right through. To do that the front sub-frame has to be removed with the diff and suspension detached beforehand. I had it done to my RRV by the selling dealer prior to pick-up, after having asked that it be done but without giving too much info on the job by only handing over the 1st page of the TSB that only described the problem, not the details of the cure.
