Automatic Transmission: Installation
WARNING: This page is about a different car, the 2006 BMW X3, 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.
- To install, reverse removal procedure. If replacing transmission, fit shift lever, bracket for cable and retainers for oxygen sensor cable from old transmission to new transmission.
- Install transfer case to transmission. Pay attention to dowel sleeves (1). See Fig 1. Replace damaged dowel sleeves. Apply a thin coat of WEICON ANTISIZE grease or equivalent to splines. Tighten transfer case screw connection on transmission to specification. See TORQUE SPECIFICATIONS .
- Note dowel sleeves. See Fig 2. Replace damaged dowel sleeves.
- Screw Special Tool (24 2 300) into tapped hole (1). See Fig 3.
- Turn torque converter until Special Tool (24 2 300) is flush with bore in driving disk. See Fig 4. Flange automatic transmission to engine.
- Bore (1) in driving disk must be accessible from aperture in oil sump. See Fig 5.
- Tighten transmission-to-engine screws to specification. See Figure. See TORQUE SPECIFICATIONS .
- Tighten torque converter-to-flywheel screws to specification. See Figure. See TORQUE SPECIFICATIONS .
- Center bearing must be aligned at right angles to propeller shaft. See Figure. Tighten nuts of center mount-to-body to specification. See TORQUE SPECIFICATIONS .
- Replace self-locking nuts of flexible disk-to-propeller shaft and transmission output flange. See Figure. Grip each screw and tighten down nut. This prevents flexible coupling from being subjected to torsion stress. Tighten to specification. See TORQUE SPECIFICATIONS .
- Tighten crossmember screws to specification. See Figure. See TORQUE SPECIFICATIONS .
- Replace sealing rings on hydraulic lines.
- Install nut for selector lever cable to specification. See TORQUE SPECIFICATIONS .
- Grip clamping sleeve (1). See Fig 6. Slacken nut (2). Press shift lever (3) forwards into park position. Press cable (4) in direction of arrow and release again. Grip clamping sleeve (1) and tighten nut (2) to specification. See TORQUE SPECIFICATIONS .
- Install front propeller shaft. See REMOVING AND INSTALLING FRONT PROPELLER SHAFT .
- To install reinforcement plate, torque screws (2) to specification. See Fig 7. See TORQUE SPECIFICATIONS .
- After completion of work, check transmission fluid level of transmission and transfer case. Top up if necessary.
