2012 was the magic year for the switchover.
Power Steering System Conversion to Dexron VI
Dexron VI fluid was introduced in the power steering systems
on the Acadia, Enclave and Traverse in production during the
There may be some questions about the use of Dexron VI fluid in
the power steering system when performing a repair on these
vehicles from a past model year: 2007-2012 Acadia, 2008-2012
Enclave, 2009-2012 Traverse, and 2007-2010 OUTLOOK.
Refer to #PI0620 for information on using Dexron VI in the power
steering system. The information includes:
• The procedure for converting the system to Dexron VI
• How to procure an identification tag for the power steering
reservoir to identify that the system has been converted
• Conditions under which this conversion should be performed
To prevent a pinion seal squeak in the future, it is recommended
to convert to Dexron VI only when a steering gear is replaced. It is
not recommended to convert to Dexron VI for any other service to
the power steering system because the pinion seal has already
been exposed to the old fluid, which is the cause of the squeak
condition. Converting to Dexron VI without changing the pinion
seal would not prevent a pinion seal squeak in the future.
Furthermore, if a squeak should develop from the steering gear
pinion seal, it is imperative to convert the system to Dexron VI
before replacing the pinion housing and inlet hose as outlined in
#PI0029F. The new housing recommended as part of this service
procedure contains a fresh seal that must not be exposed to, or
contaminated by, the old fluid or it may develop a squeak in the future.
The new inlet hose also has a larger diameter orifice to allow
for less system back pressure.
