In January of 2002, one ALLISON 9000 transmission in Tuha Oilfield broke down. Our company was asked to provide emergency maintenance by this customer. Our technicians who are servicing Qinghai Oilfield rushed there without any hesitation. And meanwhile, the urgently needed parts were dispatched immediately by air from Yantai warehouse. After 3 days of overhaul, all the performance of this transmission have been successfully resumed. Jereh achieved another success again!
