Pan with built-in filter, gasket, drain and fill plugs and 13 bolts for BMW ZF 8HP45, 8HP51 and 8HP70 fluid services. Replaces BMW 24118612901.
This is the composite oil pan with the filter built in for BMWs with the ZF eight-speed automatic, sold as BMW 24118612901 and cross-referenced to 24115A13115, 24117624192, 24117613253 and 24117604960. It covers the GA8HP45, GA8HP51 and GA8HP70 used in most 2012-and-later BMWs, from the F30 3 Series and F10 5 Series to the X3, X5 and 7 Series. If your BMW has a pan gasket weeping at the corners, harsh 2-3 or 3-2 shifts on old fluid, or you are past 60,000 miles on the original fill, this is the part that renews the filter and every pan seal in one job.
On the BMW 8HP the filter is not a separate element you swap. It is molded into the plastic pan, so replacing the filter means replacing the pan. The pan also carries the drain plug and the gasket that seals the bottom of the case under the mechatronic unit. Everything the pump feeds to the mechatronic valve body and its solenoids comes through this filter. ZF's own service information notes that 8HP fluid ages faster with frequent high-speed driving, towing and hard driving, which is why the factory lifetime fill is often not the whole story on a car that has seen real miles.
Find the leak before you blame the pan. On four- and six-cylinder cars with the N20, N26 or N55 engine, BMW issued a separate bulletin for fluid loss at the cooler line connections on the transmission. That leak runs down the side of the case and drips off the pan, so it is easy to mistake for a pan gasket. BMW's fix there is new cooler lines and O-rings, not a pan. BMW's own diagnosis bulletin for the 8HP also says to check the fluid level for every transmission complaint, even with no visible leak, and not to reset adaptations until the complaint has been verified. Our BMW 3 Series 8HP common problems and BMW 3 Series shift problems guides walk through the checks.
The listed fitment covers BMWs with the GA8HP45, GA8HP51 and GA8HP70: 2 Series F22/F23/G42, 3 Series F30/F34/G20, 4 Series F32/F33/F36/G22/G26, 5 Series F10/F11/G30, 6 Series F12/F13, 7 Series F01/F02/G12, 8 Series G14/G15/G16, X1 E84, X3 F25/G01, X4 F26/G02, X5 E70/F15/G05, X6 E71/F16/G06, X7 G07 and Z4 E89/G29. Earlier cars with the ZF six-speed use a different pan and will not take this one. Match the pan shape and the number cast or printed on your old pan before ordering, or send us the year and VIN. More eight-speed parts are in the ZF 8HP collection.
If you would rather buy the fluid and pan together, the 8HP70 service kit with pan, filter and ATF includes six liters. This is a filtration and sealing service. It will not cure internal clutch, mechatronic or converter faults. If shifts stay harsh on fresh fluid, the 8HP45 10-piece solenoid kit is the next step to check.

Yes. On the BMW 8HP the filter is built into the composite pan, so this one part replaces both. The kit also includes the pan gasket, drain plug, fill plug and 13 bolts.
No. It fits the eight-speed GA8HP45, GA8HP51 and GA8HP70. BMWs with the ZF six-speed use a different pan.
It depends on the model and how much drains out. Do not fill by volume. Fill until fluid runs out of the fill hole at 30-50 C with the engine running, as described in the ZF procedure.
It may not be. BMW issued a bulletin for fluid leaks at the transmission cooler line connections on N20, N26 and N55 cars, including the F30, F31 and F34. Clean the area and trace the leak to its highest wet point before replacing the pan.
Not as a routine step. BMW's 8HP diagnosis bulletin warns against programming or resetting adaptations unless a complaint has been verified first. Most cars drive normally after a correct fluid fill.
ZF's service information lists 10 Nm for the plastic 8HP pan, tightened crosswise from the center outward. Use the new bolts included in the kit.
