3rd Gear RPM Stutter - 2009 Subaru Legacy GT
This video shows 3 different 3rd gear accelerations in a stock 2009 Subaru Legacy GT. Procedure used for acceleration: Slow down to 30-40MPH, put the automatic transmission in 3rd gear, floor-it constantly until the top range of the gear.
Any fluctuations of the RPM needle are not caused by driver input. These stutters are a result of Subarus poor tuning ability and refusal to correct this issue. Although these stutters are rather mild, the vehicle will occasionally lurch forward violently or fail to accelerate altogether endangering the vehicle, its passengers, and other vehicles nearby. This is a safety issue!
The first acceleration is in the lower-performance mode Intelligent. In this mode, the acceleration is almost always smooth and consistent.
The next acceleration is in Sport mode. Because of the mapping used, Sport mode is not as smooth as the Intelligent mode. However, in the second acceleration, no stuttering occurred.
In the third acceleration, an RPM stutter occurs around 4500 5000 RPM. The stutter manifests by a slowing in the engine output followed by an abrupt jump in engine RPM.
After analyzing this mild stutter, it became apparent that when accelerating with the stutter, not only did the car accelerate slower, but the RPM needle first slowed down and then moved more than 9 times faster than normal during the stutter!!!
