GM Parts Product Update
Roster of competitively priced GM
Parts expands through overPOWER.
In all, some 228 distinct part numbers will
be added to the lineup of GM Parts that
authorized dealers are selling to Independent
Service Centers (ISCs) at prices competitive
with aftermarket substitutes.
The aftermarket
parts competition has
more reason to be worried.
For 2011, GM Parts is
expanding its overPOWER aftermarket parts conquest
program to bring in GM OE turbochargers, cylinder heads
and clutch kits.
Those introductions, plus the addition
of 92 new part numbers to the existing
engine component parts category, brings
the total overPOWER list to some 1,300
part numbers that also includes engines,

crate engine?
Yep. That’s right, and it’s not a typo!
GM Performance Parts (GMPP) has announced the
availability of the all-new LSX454R crate engine
(part number 19257880), drag racing engine officially
rated at 750 horsepower and 680 lb.-ft. of torque, with
a very strong, all-forged rotating assembly and optimized
high-rpm airflow developed by GMPP engineers.
“The LSX454R uses the latest LSX parts and factoryengineered technology to take LS performance to the next
level,” said Dr. Jamie Meyer, product integration manager
for GM Performance Parts. “This is a great engine to use
when building a cutting-edge drag car with one of our new
Camaro bodies in white.”
GMPP engineers designed the LSX454R for the
unique, high-rpm demands of drag racing. It is a highcompression, solid-roller combination that uses new LSX

in Las Vegas last November, GM Performance
Parts (GMPP) made clear its intention to stay
on that industry’s leading edge.
Reprising its rollout of groundbreaking E-ROD
emissions-compliant crate engine systems at SEMA 2009,
GMPP talked up three additions coming in 2011. An E-ROD
5.3L, LS7 and LSA will join the introductory LS3 in a product

Chrysler Group vehicle fluid systems
do not require regular flushing. These
systems include: engine oil, transmission oil, axle lube, brake fluid, power
steering fluid, and refrigerant. The only
exception to this requirement are those
fluid changes that are published in the
vehicle maintenance schedules, e.g.
engine coolant, and in instances where
a failure has occurred and/or the system
has become compromised, contaminated or overheated beyond the normal
operating range.
Aftermarket chemicals to flush the
engine, transmission, brake or steering
systems are not recommended.
Chemicals contained in these products
can damage the system elastomeric
components, and contaminate the
component fluid, leading to loss of system/component durability and service
life. When necessary, only the original
approved system fluid should be used
to flush these components using
approved equipment.
If the engine coolant contains a
considerable amount of sediment, clean
and flush the system followed by a
thorough rinsing to remove all deposits
and chemicals. Refill with a minimum of
a 50% mixture of the specified coolant
and distilled water.
Refer to Chrysler bulletin #26-001-09
for more information.
OnStar® Power
Consumption
2000-2010 OnStar-equipped Vehicles

During battery parasitic drain testing,
it is important to understand the power
cycles of the various OnStar systems in
order to avoid confusion about normal

All OnStar customers with currently
active vehicles have digital/analog
cellular capability. A green status LED
on the OnStar keypad normally indicates an active OnStar account. A red

grease to the rear leaf springs will
correct this condition and do a better
job of preventing the noise from reoccurring than replacement of the springs.
To grease the springs, pressure wash
the springs to remove as much dirt and
debris as possible and dry the springs
with compressed air.
Apply a liberal amount of grease
under the front and rear tip inserts for

The OnStar system will stay powered
up after the ignition is off for an extended time in order to allow for remote
services like door unlock, horn chirp,
light flash, etc., to take place as
requested by the driver. Power cycle
times vary depending on the generation
of the OnStar system, and may be
powered up continuously from 48 hours
to 120 hours after the ignition is off.
Technicians may identify the system
generation by using a scan tool or by
using www.onstarenrollment.com.
The expected current draw of the
OnStar module is:
IGN ON - 240 to 400 mA
IGN OFF - 3 to 20 mA for 48 hours

A squeak noise may be coming from
the rear of the vehicle. During normal
operation, certain vehicles may exhibit a
squeaking noise that may be traced to
the rear leaf springs. While this noise is
an operating characteristic of leaf
springs, the roads that the vehicle is
driven on will affect the frequency and
severity of this noise.
This condition may be due to debris
getting between the leaf springs. It has
been found that the application of

re-application may be necessary
throughout the life of the vehicle.
If this procedure does not correct
the noise on 1500 Series (1/2 ton)
models built prior to October 2004,
the noise may be caused by an incorrectly dimensioned splay clip (the band
holding the ends of the leafs together)
that interferes with the leaf springs. A
5 mm (0.197 in) wider splay clip was
introduced early in the 2005 model
year to provide additional clearance.
To correct this condition, it may be
necessary to replace the rear leaf
spring assembly. There was no change

aftermarket emissions requirements for on-road applications early this year. The LS3 now has that certification.
GMPP is also working to get CARB certification for its
E-ROD engines to be used in street rods, kit cars and
other specially constructed vehicles in the state.
GMPP also unveiled plans to expand its LSX line
of maximum performance parts to
include LSX-DR drag race cylinder
heads; a high-flow, singleplane intake manifold and
LSX L92-style six-bolt heads
for small-bore applications.
GM Performance Parts turned
heads at the 2010 SEMA show.
“No other manufacturer offers
more parts for building an LS engine
for the street or strip and these exciting
new parts are merely the latest examples,” says Dr. Jamie
Meyer, GMPP product integration manager. “Our LSX parts
were developed for 2,000-horsepower
racing engines and they deliver
performance and strength that
are second to none.”

GMPP also revealed the
availability of a new LS9
supercharger kit. Consisting
of the assembled supercharger,
fuel rail with injectors, integrated
throttle body and a “dual brick” intercooler, the kit gives
engine builders the resources to use
the power-adder behind the
Corvette ZR1 on any engine
with LS3 heads or the LS3
port configuration.
It announced plans to release a special-edition Camaro
every year. Its Synergy Series, which debuted in a show car
at SEMA, will emphasize new approaches to accessory parts
and customization. The car will be offered to consumers
in the first half of 2011 as a special-edition model.

Information
comes together on
retooled GM Parts website:
www.genuinegmparts.com
A Genuine Resource
When you’ve got a job to do, you need everything in
one place, ready to go — the vehicle, parts, tools and labor.
Same goes for the information you may need before you
get down to work.
That’s why GM has completely redesigned its
Genuine GM Parts website. At www.genuinegmparts.com,
Independent Body Shops (IBSs) and Independent Service
Centers (ISCs) can find information needed to do top-notch
work on GM vehicles in one place, and now better assembled, organized and easier to retrieve than ever before.
The redesigned site, which launched in 2010, is
close to being fully functional in the new configuration.
Navigation will be easier, information more accessible,
and the breadth and depth of resources
will be expanded.
Though the site’s main draw is collision
repair procedure information — a section
that is being upgraded to be more user-friendly
and visual — GM is enhancing the site’s
GM Powertrain resources.
“There will be a lot more GM Powertrain
information, and all of it will be incorporated into the
site rather than linked to other sites,” says Cindy Schafer,
digital marketing manager on the GM Parts wholesale
marketing team. “And we’ll also be incorporating an email
registration form for visitors to receive emails specific to
collision, powertrain, GM Performance Parts and ACDelco
product information.”
Collision Repair
In the Collision Repair section, visitors navigate
directly to repair procedures information
pertaining to specific GM makes and
models. Available information
spans multiple categories,
from technical documents
and procedures and service
bulletins to warranty provisions, paint shop guidelines
and position statements.
The aim is to leave no
stone unturned in giving
IBSs a relevant source of
OE information that
is constantly updated
to help them restore each
GM vehicle to pre-crash
conditions. And that’s becoming
increasingly difficult for IBSs to achieve
with repair procedures and processes coming at
a quicker pace, more competition from non-OE parts
and a greater use of advanced structural technologies
like high-strength steel.
Powertrain Repair
Likewise, in the Powertrain section, visitors can
learn all about the full lineup of GM engines, engine
components, transmissions, transmission components
and transfer cases.
GM Engine resources are designed to give ISCs
essential information needed to sell, select and install
parts necessary in any GM vehicle repair. This information
spans engine spec charts, GMPP crate engine listings and
GM Parts warranties to listings of ACDelco Parts such
as cooler lines, fittings, manifolds and gaskets, and
tensioners/balancers/pulleys. This type of detailed information can help ISCs make the best choice for customers.
GM Transmission resources are equally comprehensive.
You can find a review of GM remanufactured transmission
features, GM Transmission parts advantages, warranty
features, specification charts and quick reference
information on GM Parts and/or ACDelco Parts.
GM Performance Parts
Releases 2011 Catalog
A pair of dealer-modified Camaros featured on the
cover of the 2011 GMPP catalog exemplify a growing
trend in using crate engines to offer extraordinary
performance to a new
generation of enthusiasts —
all while evoking the spirit
of the dealer-driven COPO
Camaros of the late 1960s.
The Camaros were built by
DeNooyer Chevrolet in New
York and Georgia’s NeSmith
Chevrolet. DeNooyer used
GMPP’s new LSX454 crate
engine to build a modern
454 engine for the Camaro
SS, while NeSmith
transplanted the
supercharged LS9 engine from
the Corvette ZR1 into their Camaro.
Within the new 2011 GM Performance Parts catalog are
more than 300 pages of crate engines, engine parts and
vehicle accessories for vehicles powered by GM’s LS, smallblock and big-block engines.
For 2011, the catalog features more for LS highperformance engine builders, including:
• Vehicle-specific performance parts and accessories
• Expansion of the E-ROD crate engine portfolio
• The LSX454R crate engine
• LSX DR 11-degree cylinder heads and matching
intake manifold
• LSX six-bolt L92-style cylinder heads for
smaller-bore LS engine.
Along with descriptions and part numbers for all the
engines, parts and accessories, the GMPP catalog offers
valuable information on selecting matching components
for the best-performing combination, as well as detailed
specifications on most components — including charts
outlining cylinder head specs and camshaft specs. There’s
also a special section for LS engine builders that provides an
overview of the LS engine family and parts interchangeability.
GMPP has also included accessories for new Chevrolets,
including the Corvette, Camaro, Cruze and trucks. They
include performance, suspension and appearance upgrades.
Contact your GM dealer for a copy of the 2011 GM Performance Parts catalog. A free download of a PDF version of the
catalog is also available at www.gmperformanceparts.com.

Business of Repairs
Shifting Demand
Vegas transmission
shop’s rebuild biz still
flickers but remans
are the future.
It’s a sign of the times, perhaps.
Someone comes into Jim Marynow’s Las Vegas transmission shop with a 20-year-old vehicle dragging a wornout transmission. It can be fixed, he tells them, but at a
cost of $2,000, normally a hard sell. “Deal,” they’ll say.
“A lot of times I’ll do these cars that have 150,000
miles and I’ll just shake my head,” he says. “But people
are wanting to keep their cars longer, and they don’t
want to spend money on a new car and take on
the debt. The thinking is, just get by for a while
on the old one.”
10
Jan – Mar 2011 ServiceInsights
Marynow built Competition Transmission on that
type of work, and demand for it has ticked up lately
with the tough economy. But after 30 years of rebuilding
transmissions, he’s seeing a shift. Now, steadily more
of his business revolves around installing remanufactured
transmissions.
The reasons are many, he says. More complex
vehicles and transmissions, greater interest from OE
suppliers, attractive warranties, a better value proposition
and a superior product are making remanufactured
transmissions more attractive. They may turn less quick
profit than repairs, but Marynow finds it increasingly tough
to tell his average major overhaul candidate with a straight
face they’re better off repairing.
“It’s probably more profitable for me to fix them
here, but it ends up better for the customer if they buy
a replacement,” he says. “It pays off in the long run for
both of us.”
Especially, Marynow says, if the reman is an OE product.
Products supplied by automakers typically come fully
updated, painstakingly reassembled, backed by strong
warranties, and are readily
sourced through
and supported
by a strong
network of
parts dealers.
The end result of most GM Powertrain
transmission jobs at Competition is a speedy
installation, a transmission that works like new and
satisfied customers, few, if any of whom, ever come
back. But that’s a good thing, Marynow says. In this
business, of course, a satisfied customer is one who
doesn’t come back, at least not that often.
“Very few GM reman jobs come back to us or anyone
else for warranty work,” he says.
Remanufactured transmissions offered through
GM Powertrain offer a great example. Marynow installs
some 50 to 60 a year, mostly workhorses like 4L60Es,
4T65Es and 4T60Es. Supplied by a local GM Parts
dealer, they offer the speediest, most reliable
solution for the GM customer facing a major
overhaul, he says. Easy to install, especially with
ready GM support, and carrying 3-year, 100,000-mile
warranties, the transmissions deliver a peace of mind
hard to duplicate with either rebuilds or non-OE remans.
“In the end, the customer wins,” he says. “There’s no
guesswork with these transmissions, each component
is broken down and checked. You can rely on them.
And the nationwide warranty is something that’s
hard to match on a rebuild that I might do.”
From his shop’s perspective, a GM reman usually means
an easier job. Because they’re from the vehicle maker,
they’re easy to install. Plus, they’re sourced quickly from
the local GM Parts dealer. If installation problems crop up,
the dealer is there to help, as is GM technical support.
“We’ve taken advantage of the GM toll-free
support,” he says. “We had one recently where there
was a transmission with a wiring problem. We took
the diagnostic code, gave it to the GM rep and he faxed
information on a diagnostic flow chart. We identified
the problem as a loose ground and solved it. Without
that help, we’re just throwing darts.”
