Everything to service a ZF 6HP19: pan with the filter bonded in, 24 pan bolts, fill plug, valve body sleeve seals, 6L ATF and a fill pump.
If your BMW with the ZF 6HP19 six-speed automatic has a wet transmission connector, a weep around the pan, or fluid that has never been changed because it was sold as filled for life, this is the one-box service. Kit 333 907 KIT puts the new oil pan with its built-in filter, 24 pan bolts, a fill plug, a replacement mechatronic sealing sleeve with O-rings, six 1-liter bottles of German-made ATF and a hand fluid pump in a single order, so the car is not sitting on stands waiting for a second shipment. Owners usually find it while chasing a harsh 1-2 or 2-3 shift, a lockup shudder, or a transmission fault light on a six-cylinder 3 Series or 5 Series.
The 6HP19 has no separate filter element you can unbolt and swap. The filter is part of the pan, so the old pan and its trapped debris come off together and a clean pan goes on in one piece. Directly above the pan sits the mechatronic unit, the combined valve body and transmission control module inside the transmission. Everything the solenoids and clutch packs rely on passes through that filter first, and when the fluid is worn out the valve bores in the mechatronic wear with it.
Read the ZF tag on the side of the case first. BMW used both the first-generation 6HP19 and the second-generation 6HP21 in the same body styles, and BMW literature often labels both GA6HP19Z, so the tag is the only certain answer. Then look at the connector. A damp plug with no codes is a sleeve job. If a drained sample smells burnt or the pan holds large chips or fragments, ZF's own service information says to stop the oil change and have the unit inspected, because fresh fluid will not fix mechanical damage. Our ZF 6HP filter and pan service guide walks through the inspection, and the BMW 3 Series 6HP problems guide covers the shift complaints that a service can and cannot cure.
This kit is listed for the ZF 6HP19 six-speed automatic in BMW applications. In the E60 and E61 5 Series, BMW's sleeve bulletin puts the six-cylinder 525i, 528i, 530i and 535i on the 6HP19 or 6HP21, and the E9x 3 Series also used both units. Because the pan, bolt count and sleeve differ between families, match the tag on your case to 6HP19, or send us your year and VIN before ordering and we will check it. V8 cars run the 6HP26 and need the 6HP26 kit instead. You can see every 6HP part we stock on the ZF 6HP transmission parts page.
Ships fast from the USA, packed with the fluid, at about 19 pounds.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the ZF 6HP19 in BMW applications, which includes six-cylinder E60/E61 5 Series and E9x 3 Series cars that came with that unit. Some of those cars have the later 6HP21 instead, so read the ZF tag on the case or send us your year and VIN and we will confirm it before it ships.
On the 6HP19 the filter is built into the pan. There is no separate element to replace, so the pan and filter are serviced as one assembly.
The sleeve carries the wiring from the outside connector into the mechatronic unit. When its O-rings harden, fluid wicks into the connector and can cause shift faults. The pan has to come off to reach it, so replace it during this service even if the plug is only damp.
ZF approves ZF LifeguardFluid 6 for the 6HP19. Six liters covers a pan drop and refill. A full flush or a cooler line service takes more, so order an extra case if you plan one.
There is no dipstick. With the car level and the engine idling in Park, fill until fluid runs out of the fill hole with the transmission fluid between 30 and 35 C on a scan tool, then install the fill plug.
It often helps when the fluid is old, but it will not repair worn valve bores, failed solenoids or burnt clutches. If the pan has large chips or the fluid smells burnt, have the transmission inspected before spending money on a service.
