This service bulletin provides information on some vehicles that may rock or move slightly forward or rearward while in Park at start up after cold soak. This condition may be accompanied by a clunk noise. This is a slight movement that is more often seen visually, rather than felt, when viewed from the outside and using the auto-start feature, if equipped.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

The failure pattern owners describe
Owners of 2007 Equinoxes report critical powertrain failures across multiple systems. Engine stalling occurs while driving—vehicles shut off on highways, require coasting to a stop, and sometimes won't restart without waiting. One owner's oxygen sensor replacement didn't solve the recurring stalling problem.
Transmission problems appear early: some owners replaced the transmission before 4,000 miles when it stuck in second gear; others report it won't shift into third or higher gears without lifting off the throttle. Severe jerking and shaking during acceleration occur even after a $298 fuel system cleaning and transmission fluid service.
Electronic stability control and traction control systems malfunction repeatedly, triggering "Service StabiliTrak," "Service Traction Control," and "Engine Power Reduced" warnings. When these activate, the vehicle loses power and cannot exceed 20 mph. Dealership diagnostics haven't fixed the problem.
Ignition keys stick in the switch repeatedly—owners can't extract them without restarting the engine and shifting in and out of gear multiple times. One repair cost $544.
Other issues include a fuel pump line leak (owner paid $949), driveline vibration at highway speeds that persists after tire replacement, sudden power steering failure with no warning, and heater core rupture while driving. Owners report multiple shop visits and weeks in the shop without permanent resolution to many failures.
