What are the reasons for the inability to gain speed in 5th gear?

The reasons for the inability to gain speed in 5th gear: insufficient transmission fluid or dirty transmission fluid. Insufficient transmission fluid: Check the transmission fluid level. If the level is too low or too high, adjustments should be made. Both low and high fluid levels, as well as transmission fluid leaks, can easily cause the oil pump to draw in air, leading to poor lubrication and incomplete operation, resulting in slipping. Dirty transmission fluid: If the fluid appears dark brown or has a burnt smell, it indicates that the transmission fluid is very dirty. In severe cases, it can even clog the oil passages, causing abnormal operation of the transmission valve body. In this case, the transmission fluid needs to be replaced.
