I am going to purchase the zf6hp26 sump pan and the other bits some kits have
6 litres of lifeguard 6 and some have 7 litres for any one who has done this them selfs how many litres did they use to refill the box as there is a price margin between the kits that 6 litres and those that have 7 litres

 

It depends upon how long you allow the unit to drain after you have removed the pan. If you allow an hour or two of drainage, 6 litres of fresh ATF is typically enough. If you allow the unit to drain overnight, you may need 7 litres (or even a little more) of fresh ATF....

 

it will proubaly be an hour to 2 hours drainage an indi is going to do it they once the box is cold they will then drain it and fit new pan sleeve and oil which I will be supplying

 

Mine took a little over seven. And be sure to follow the technique to fill to the correct level.

 

Mine took 6.4 I let it drain for several hours ,
I also jacked the car up on all sorts of angles which helped also turned the engine a couple of times , there is a sweet spot when spinning the engine that gets a good bit more from the torque converter, but i guess the steel pan will be differant to some degree , obveastly not by much .
I waisted a small amount whilst levelling it off , as I done that twice on two heat cycles to be sure !
+7 litres is the most I've heard of as from this thread , prior to that the most I've seen added was under 7 litres across many treads . But one thing I noticed across all the threads I read on the subject , is everyone puts in a slightly diferent amount back in to achieve the same result , so there is no science to it bar luck . The more you get out and in the better !

 

Ok I bought a kit that has 6 litres and bought an extra 1 litre bottle just in case now contemplating whether to do it myself I have been told of a good indie who is about 23 miles away whose lobour price is very good I do have a main dealer 1 minutes drive away but main dealer labour prices are too high
