Attention:
Be advised that failures of this nature are generally caused by customer abuse. They are NOT defects in materials or workmanship for which General
Motors would be responsible for and should not be covered under the terms of the new vehicle warranty.
Vehicles with this complaint should be inspected by your service manager and District Service Manager (Warranty Manager in Canada). A field product
report should be submitted on each case. Also, if aftermarket kits are added that may effect the driveline loads,
the transmission would not be warranted.
Condition
Some customers may comment about a slipping clutch. Upon further investigation, the technician will find transmission oil in the clutch housing.
Cause
This condition may be caused by excessive front wheel hop during wide open throttle (WOT) acceleration events. Excessive wheel hop transmits a
torsional shock load into the transmission case. This may cause the transmission case to fracture (as shown in graphic below) and transmission fluid to
leak into the clutch housing.
