Automatic Transmission: Installation

WARNING: This page is about a different car, the 2005 BMW X3 and 2004 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Oil cooler and lines must always be flushed before a replacement transmission is installed.
CAUTION: When joining up engine and transmission, ensure ease of movement of torque converter.
  1. If replacing transmission, fit shift lever, brackets for cables and retainers from old transmission to new transmission.
  2. Check dowel sleeves (1) and (2) for correct seating. See Fig 1 . Replace damaged dowel sleeves.
  3. The sheet metal flywheel is equipped with three recesses for the torque converter retaining tabs. See Fig 2 . When guiding the engine and transmission together the three mounting tabs on the torque converter must be aligned with the three indentations in the sheet metal flywheel. Non-conformance leads to follow-up damage on the automatic transmission. Turning on the torque converter, or engine, is no longer possible after guiding the engine and transmission together and would lead to damage.
