Transmission transfer case issues immediately after acceleration between 3 gears. . . Car transmissions "stumbles" (transmission locking). Well known issue in the Porsche community and Porsche solution is does not fix the issue. No engine error codes issued as well. Porsche says cannot duplicate problem. This has been happening for quite a while until I researched the issues online. Previouse recall # 03v351000 - Porsche will not currently honor this recall.
