It is typically okay to use synthetic ATF to top off a transmission originally filled with conventional ATF, or to replace conventional ATF in a transmission. However, you should always check with the manufacturer of the synthetic ATF you want to use if it is compatible with conventional fluids, and if it meets the requirements for your application.
