The clutch basket serves the purpose of ensuring that the series of plates, clutch springs, and spacers placed within it can properly facilitate the operation of the transfer case clutch.<\/p>\n
Common symptoms include a noticeable jerking or shuddering sensation during acceleration, especially from a standstill or at low speeds. You might also hear clicking noises or experience ‘binding’ during sharp turns. These issues often stem from worn-out grooves in the clutch basket or overheated plates.<\/p>\n<\/details>\n Yes, the ATC450 transfer case was primarily used in BMW X5 (E70 LCI) and X6 (E71) models produced between 2010 and 2013. If your vehicle uses the ATC450 unit, this gear assembly with the drum clutch is the correct replacement part.<\/p>\n<\/details>\n While you can sometimes replace plates alone, the drum (clutch basket) often develops deep grooves where the plates sit. If these grooves are present, new plates will get stuck, leading to continued jerking. Replacing the entire assembly ensures smooth movement and a longer-lasting repair.<\/p>\n<\/details>\n The most common causes are internal oil degradation, using mismatched tire sizes (which puts constant strain on the clutch), or aggressive driving. We recommend changing your transfer case fluid every 60,000 km to prevent heat damage to the drum and plates.<\/p>\n<\/details>\n Yes. After replacing internal components of the ATC450 transfer case, you must perform a ‘VTG calibration’ using a diagnostic tool (like ISTA). This resets the wear integrators and tells the actuator motor the new thickness of the clutch pack.<\/p>\n<\/details>\n<\/div>\nWill this assembly fit my 2012 BMW X5 E70?<\/summary>\n
