BAIC Saab was established in the 1990s. It was originally a Swedish luxury car brand and was later acquired by Chinese companies. It mainly produces high-end sports cars.
The word “Saab” first appeared in Hong Kong car magazines. It is the Hong Kong translation of the Swedish luxury car brand Saab Saab. When it was introduced into China in the early 1990s, it was on the same footing as high-end cars such as Mercedes-Benz and BMW. The outstanding performance of its products is even more important. Won the praise of the “King of Pioneers”. Saab has created many precedents in the history of automotive technology, such as “the first application of aviation turbocharged engine technology to civilian vehicles”,”rear wheel servo steering system”, and “reindeer horn safety body”. Its persistent pursuit in terms of technology and safety made it a Swedish royal car. Beijing Automobile named the mid-to-high-end brand after “Saab”, which is not only “inherited”, but is the best explanation for Beijing Automobile’s acquisition of Saab’s core intellectual property rights; it is also the best interpretation of Beijing Automobile’s commitment to Saab’s pursuit of car building concepts in technology, performance and safety.

This maintenance was mainly due to the valve body failure causing upshift slippage. The internal parts were tested to be intact, the internal rubber ring repair package was replaced, and the internal oil in the gearbox was replaced, and the valve body was replaced. The failure disappeared.
Friendly reminder: Due to the rising temperature in summer, the vehicle will feel frustrated and lock up. In serious cases, the vehicle will not be able to move, the fuel consumption will be too high, and the quality of shifting is poor. If the above situation occurs, please repair it promptly! Please pay attention to maintaining your car!
