Can a transmission fluid replacement cause to fail?

In general, a transmission fluid replacement is done to maintain the proper functioning of the transmission. However, in certain cases, a transmission fluid replacement can cause a transmission to fail if it is not done properly. For example, if the wrong type of transmission fluid is used or if the fluid is not filled to the proper level, it can cause damage to the transmission and lead to its failure. Additionally, if the transmission fluid is not changed according to the recommended maintenance schedule, it can become dirty and contaminated, which can also lead to transmission failure. Therefore, it is important to have the transmission fluid changed by a qualified mechanic who can ensure that the right type of fluid is used and that it is filled to the proper level.
