SUBJECT
Transmission Failures Due to Incorrect Installation
MODEL
All
SITUATION
Transmission failure and damage can result from the incorrect installation of the transmission.
These transmission failures and or damages are often caused by damaged, misaligned or missing dowel bushings between the engine block and the
transmission housing. The resulting transmission-to-engine misalignment will gradually wear off the splines on the input shaft of the clutch cylinder
until power transfer is no longer possible.
The failure symptom relating to the misalignment is a popping sound while driving,loss of forward and reverse gears and finally totals failure of the2010 BMW X6 (E71) V8-4.4L Turbo (N63)

transmission. Transmission failure may occur between 1,000 and 25,000 miles after removal of the engine and or transmission depending on the
severity of the misalignment.
Misalignment of the transmission to the engine can also occur as a result of improper engine removal procedures (transmission is left in vehicle
during short block replacement), etc.
It is imperative that the proper procedures, tools and equipment necessary to repair or replace an engine or transmission be used. Additional
installation information can be found in SI B11 05 11 "Engine Removal and Installation Tips".
See attached document describing the damage that will result from improper transmission installation.
WARRANTY INFORMATION
The warranty does not apply to the following:
Damage that results from improper repair.

SITUATION
If repairs involving the removal and installation of the engine become necessary, the transmission must always be removed first as outlined in the
repair manual.
Note:
Always support the engine and transmission using the appropriate special tools to avoid automatic transmission oil pump damage due to engine and
transmission "sagging" at the mating point (engine block to transmission bell housing) before the fastening bolts are removed.
Before reinstallation of the transmission, the dowel sleeves must be removed from the transmission bell housing and installed in the engine block as
outlined in the repair manual and shown in the illustration below.
Note:
The transmission bell housing and engine block mating surfaces must always seat flush with each other (dowels seated in holes) before the bolts are
installed and tightened to avoid damage as seen in the illustrations below.
Failure to follow the proper repair procedures will result in engine and or transmission damage due to engine/transmission misalignment.
