Inquiry Regarding the Automatic Transmission of the 1998 840Ci

[Inspirli]

Today, when inspecting under the vehicle, I saw that the oil lines from the gearbox to the cooler radiator exhibit significant corrosion. I cleaned and painted them years ago, but they need attention once again. Preserving them would be advantageous, since their replacement is somewhat costly. I would want to detach them off the vehicle, remove rust, apply paint, and then reattach them. This entails changing the seals for the pipes connected to the gearbox. The issue is as follows. RealOEM indicates that both pipes connect to the gearbox with a union and an O-ring; nevertheless, in my gearbox, one pipe connects with a union while the other uses a big banjo bolt. Is the incorrect gearbox installed?

UPDATE: I appreciate the responses from everybody. The issue has been resolved, courtesy to my esteemed buddy Kamil at BMW Huddersfield. The RealOEM design is generic and inaccurate, although the component numbers for the pipes are right. The banjo bolt and seals for BMW are only obtainable as part of the full pipe, which remains accessible from Germany for around £130.

Simply have new ones fabricated.

Thank you for your response. Originals seem to be accessible from BMW for around £250 for the pair; but, if RealOEM is accurate, they would be incompatible with my vehicle. Even if I procured new ones, I would still need new seals for the gearbox end, which is the primary focus of the discussion.

Diagrams may not always accurately depict the components, therefore use caution in placing excessive trust on them.

The seals will not possess any distinctive qualities. The banjo bolt will likely have either a copper seal or a bonded rubber seal. Dowty.
