REMOVAL PROCEDURE IMPORTANT: The fuel injector wiring harness connector; must be connected to their respective fuel injectors. Failure to connect the fuel injector connectors to their respective fuel injectors may result in excessive exhaust emissions and poor engine performance. 1. 2. 3. 4. 5. Disconnect the battery ground (negative) cable. Remove the upper intake manifold. Remove the engine left side valve rocker arm cover. Remove the engine right side valve rocker arm cover. Disconnect the wiring harness from the Engine Coolant Temperature (ECT) sensor. IMPORTANT: Use masking tape or another appropriate method in order to identify each fuel injector wiring harness connector cylinder number. 6. Disconnect and remove the fuel injector, Manifold Air Pressure (MAP) and Engine Coolant Temperature wiring harness. 7. Disconnect the fuel hoses from the fuel rail. 8. Remove the fuel rail. 9. Remove the power steering pump from the front engine cover and reposition aside.

Subject: Engagement Time of Electronically Controlled Transmissions in General Motors Vehicles (Garage Shins, Park to Reverse, Neutral to Drive, Neutral to Reverse, Park to Drive, Delayed Engagement) Models: 2000-2002 Chevrolet Cámaro 2000-2005 Chevrolet Corvette 2000-2002 Pontiac Firebird 2004-2006 Pontiac GTO 2000-2007 All GM Light Duty Trucks 2003-2007 HUMMER H2 2006-2007 HUMMER H3 2005-2007 Saab 9-7X with 4L60-E (RPO M30) or 4L65-E (RPO M32) Automatic Transmission Supercede: This bulletin is being revised to remove 2006-2007 Chevrolet Corvettes. Please discard Corporate Bulletin Number 03-07-30-007C (Section 07 – Transmission/Transaxle). Park/Neutral to Reverse or Drive (commonly called garage shift) engagement times may be different from what many customers might be accustomed to especially if they have recently traded for a General Motors vehicle. Normal Park/Neutral to Reverse or Drive engagement time will be in the vicinity of one (1) second if the automatic transmission fluid (ATF) is above 0°C (32°F) . When the ATF is colder than 0°C (32°F), the engagement time will become longer the colder the transmission fluid. A time limit factor cannot be placed on proper engagement times because the factors that affect transmission operation are many. At the moment of engine start, for economy and emission requirements, the transmission line pressure is maintained at low levels. This allows a lower cold idle engine RPM (the colder the oil is the higher the energy level (engine torque output) required to pressurize the oil).
