Well I did the tranny flush today using the bottom hose method as detailed in the Haynes manual and found it very easy. You don't have to remove and install the battery multiple times at all and it is a good time to clean up the battery tray and check the connections on the cruise control as it is located under the battery tray in the S70. I don't know why the plastic cover under the radiator had to be removed or the car jacked up as recommended in the manual. Doing it again I wouldn't bother with these 2 steps as detailed in the manual. In all I used a total of 10 litres of fluid, and even though the transmission was shifting very smoothly before, I can certainly notice an improvement following the flush. A 1/2 inch ID hose is pushed onto the end of the hose which is unscrewed from the union on the transmission housing and is held in place by screwing the union nut onto the outside of the house - very neat and reliable. When you see bubbles in the clear plastic hose stop the engine and add 2 litres of fluid into the dipstic holder. Repeat the process as per the manual until the fluid runs the same colour as the new stuff. Very simple and straightforward. Also replaced the engine oil, filter, drain plug washer, cleaned the flame trap (wasn't one) and the throttle body so it was a very productive weekend.

Cheers,

Phil
