ZF 5HP24 automatic gearbox.

Getting the valve body out.






I brought the gearbox into my garage and turned it upside down for easy access to the oilpan. I put a tray under it because the oil that's left in it will flow out of the breather hole on top.

Removed the oilpan.

Removed the filter which is held in by 2 torx-27 screws.

Getting the valve body out requires to unscrew 17 torx-bolts out and 5 extra short ones. The bolts you want to get out are typically equipped with a larger head (12mm), leave the small headed bolts alone while they hold the valve body together. The 2 bolts at the front of the gearbox cannot been seen in this photo, that's why I put 2 red arrows in it so you know where to find them. The rest of the bolts to remove are indicated with a red circle.

Lift the valve body straight up. When you're working under a car it's a good idea to leave 2 bolts in the holes, loosen them but don't take them out. The valve body is quite heavy, hold it up with one hand and get the two remaining bolts out, this way you prevent the last bolt from bending. And here it is.

This is how the gearbox looks like underneath the valve body. This one is very clean, no signs of overheating or wear whatsoever.

I let it drain the rest of the oil off by gravity on an old newspaper, then put it in a plastic bag to keep it clean.

Now I'm ready to get the BMW 740i into my garage and on the carlift to start the transplant.

I bought a new filter, 10 liters (somewhat more than 2.7 US gallons) of oil and a new gasket in advance, those things you really want to replace when you're opening up an automatic gearbox. Doesn't matter which make. Also be very sure you buy the right spec oil for your gearbox!
