![]() The official recommendation from ZF, was a FLUSH (Not an oil change) at 75k miles This has now been revised to a flush, at anything between 50k-75k miles As has been stated, a drain and refill replaces 4 litres of oil. A "Double Flush" replaces 4 litres, which then dilutes with the old oil still in the box. You will be lucky if this method replaces 50% of the old oil. A Flush is the only way to replace all of the oil in the gearbox and torque convertor, with minimal contamination I actually flushed an FFRR a few weeks back, 07MY with 55k miles. This is the oil that came out...

The sealed for life is not really sealed for life and the official recommendation is 100k miles. The transmission filter and pan are a single unit and the drain plug simply comes out when you turn it, like normal. Then remove the pan/filter unit, replace and refill. Now that is very straightforward (done it a few times on the MY 2006 SC when the cooler ruptured, mixing ATF with coolant).

I filled the gearbox with the garden spray bottle first (the type that you pump up) until it starts running from the hole. Then start the engine after closing the plug and run it for a few minutes through the gears. Then open the plug hole and fill till it comes out with running engine. Of course all the safety things in place (in park plus parking brake plus blocks on the wheels).
