When the engine is first started, some vehicles may exhibit a loud ticking noise from the variable valve timing
(VVT). This is caused by the lock pin of the variable valve timing actuator not fully engaging. Heat treatment has
now been added around the hole of the variable valve timing rotor lock pin to prevent this from happening

If no mark is present, mark bottom edge of coil spring for reassembly reference. Fig. 5: Exploded View Of Strut Assembly (Elantra & Tiburon Shown; Others Are Similar) Disassembly Mount strut assembly in vise. Compress coil spring using coil spring compressor. Remove self-locking bearing nut with Spanner Wrench while holding upper spring seat. See SPECIAL TOOLS table. Remove insulator and spring seat. Remove rubber bumper and dust cover. See Fig. 5 . Slowly release coil spring compressor tension. Remove coil spring. Inspection Check parts for deterioration or damage. Check strut assembly for leaks and proper operation. Replace strut if fluid leakage exists. Replace worn or damaged parts. Reassembly 1. To reassemble, reverse disassembly procedure. Place coil spring identification mark toward knuckle. Ensure “D” shaped upper seat hole is aligned with notch in piston rod. Align coil spring ends in spring seat grooves. 2. Pack insulator bearing with grease and install dust cap. Avoid getting grease on insulators. Compress coil spring. Install rubber bumper and dust cover, spring seat and insulator. Using spanner wrench, tighten strut piston assembly lock nut to specification. See TORQUE SPECIFICATIONS . Installation To install, reverse removal procedure.

Typically, the throttle plate angle parameter is 12-20% at time of condition with vehicle speed of approximately 24-40 km/h (15-25 mph). The customer may describe the condition as slip or delayed shift into second. Correction Replace the complete second clutch assembly with service kit, P/N 24240561. Refer to the GM Unit Repair Service Manual for the year and model of the vehicle being serviced for the 2nd Clutch service procedure. This service kit contains: Second Clutch Housing Fluid Seal Rings (613), a Second Clutch Assembly (617), a Case Cover (Channel Plate) Upper Gasket (430), and a Case Cover (Channel Plate) Lower Gasket (429). In addition to the content of this service kit, other gaskets not included in this service kit will also be needed to complete the repair – a Case Cover Lower Gasket (429), and a Case Cover Upper Gasket (430). These gaskets can be obtained by ordering gasket kit 24206391. Be sure to use ONLY the Second Clutch Assembly and Second Clutch Housing Fluid Seal Rings provided in this service kit. DISCARD the Second Clutch Assembly and Second Clutch Housing Fluid Seal Rings removed from the transmission being serviced. Disassemble ONLY the Oil Pump Assembly from the Case Cover (Complete). DO NOT disassemble the Control Valve Body from the Case Cover. Remove ONLY the Case Cover-to-Case bolts to remove the Case Cover and Valve Body from Transmission Case AS AN ASSEMBLY . To access all Case Cover-to-Case bolts, it is necessary to remove the Pressure Control Solenoid Valve Assembly (322), and 1-2 & 3-4 Shift Solenoid Valve

Some customers whose vehicles are operated in dusty type environments, such as farming or mining off-road type applications, may comment about the illumination of the check engine light, with a DTC of P0446 (Restricted/Blocked EVAP Vent Path) being set. Cause Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause this condition. Correction (1999-2007 Classic/Old Style Models) After following the published SI diagnostics for P0446 and determining that the EVAP canister vent valve is the cause of the MIL light, replace the existing EVAP canister vent valve assembly with a new assembly. This new assembly is a sealed unit that is designed to be vented through a remote filter box. To ensure correct installation, follow the procedures below.

This PI was superseded to advise dealers there is no repair for early oil change messages or erratic OlM operation. Please discard PIP4540B. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition I Concern: A dealer may encounter a customer concern of the oil life monitor (OlM) percentage dropping too qUickly, or an early oil change message. A customer utilizing the oil life monitor may be directed to change the oil at (or near) 1000 mile intervals. Recommendation Ilnstructions: Please do not replace the IPC or ECM for an early oil change message. Oil life monitoring is dependent on vehicle use. Oil life monitoring and change intervals will differ depending on how the vehicle is driven. Please complete the current SI diagnostics for any trouble code or symptom found. Engine drivability concerns may induce early oil change messages or erratic OlM operation. Dealers should verify there are no intake or exhaust leaks by completing Charge Air Cooler Diagnosis (Full System Air leak Test and the Induction System Smoke Test). Discuss driving habits with the customer. The main contributor to early or erratic oil change messages may be some of the customers driving habits. Drive cycles that include short trip, stop and go, and extended idle times are a few of the contributors to early oil change messages. Customers with more exhaust regenerations (due to driving habits) are more susceptible to qUicker oil change messages. There is no repair for early oil change messages or erratic OlM operation. If a dealer is to encounter a vehicle with a customer concern of early oil change complete a Field Product Report using the newest version of bulletin 02-00-89-002. Note: If an oil analysis has been completed fuel dilution should not be over 12%.
