What's the dirty performance of the BMW X3 automatic transmission?
The gearbox body dirty will lead to a strong sense of shift abort, not lifting gear, or lock
General BMW appeared shift impact, only to replace the valve assembly or transmission assembly
The main reason is the impact of abortive gearbox internal formation of impurities and dirt resistant, these impurities and dirt will plug the pipeline control, automatic control valve to delay, caused by gearbox setback cause shock; a gearbox problem is the gearbox oil temperature. The quality and characteristics of high temperature friction will damage the gearbox oil, increase friction and wear, gearbox noise followed, at the same time, sludge (impurities or dirt) will also be in the internal transmission (e.g. body), lead to automatic control valve is delayed, resulting in gearbox setback impact. Now the solution is simple, does not need to overhaul, how to solve, Baidu Marty gearbox solutions on the line, said very detailed, their research. Hope to help you.
