Hi guys,
My 3IS F Sport has 90,000kms on it now. Despite the gearbox being listed as having "lifetime oil" I want to service it around the 100K mark for piece of mind. From researching there is plenty of info on the 2IS 6 speed but very little info on servicing the 3IS 8 speed. I have found a transmission specialist who is confident in servicing the unit performing a full flush but he is saying the filter would not be changed as it is mounted behind the valve body similar to ZF boxes? Anyone have any experience in this area or have had the box serviced. My other option is to simply have a dump and refill which is only a partial change which would at least ensure the levels are resurrected which from research is pretty critical to these boxes operating to their optimum as they are quite sensitive to dropping slightly in oil level through evaporation over time...…. Thoughts
Cheers......
