| Models: | 1998 Oldsmobile Intrigue | 
| with 3.8 L V6 Engine (VIN K - RPO L36 ) and Hydra-Matic 4T65-E Transaxle (RPO M15) | 
Some owners may comment about a buzz type noise on decel at approximately 17-21 mph (27-34 kph) during the coast-down shift.
Condition may be due to high line pressure on decel causing pressure regulator valve instability.
Check cooler line routing for ground-out against body/frame. If no ground-out condition exists, reprogram the Powertrain Control Module with the appropriuate calibration listed below.
