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).

Pull the plastic cap back from the quick connect fining and down along the cooler line about 5 cm (2 inch) . 2. Using a bent-tip screwdriver, pull on one of the open ends of the retaining ring in order to rotate the retaining ring around the quick connect fining until the retaining ring is out of position and can be completely removed. 3. Remove the retaining ring from the quick connect fitting. 4. Discard the retaining ring. 5. Pull the cooler line straight out from the quick connect fitting. Installation Procedure Important: Do not reuse any of existing fittings if there is excessive corrosion. Do not reuse any of the existing retaining rings that were removed from the existing quick connect fittings. All retaining rings being installed must be new. Ensure the following procedures are performed when installing the new retaining rings onto the fittings.
