This is remanufactered white plug solenoid for the 5-45RFE. It is designated 5-45RFE because it was designed to fit the 5 speed transmission. This solenoid will also fit where the black plug solenoid is used in the earlier dodge vehicles from 1999/2003. 

You will need to use an updated TRS cam bracket to replace the earlier black plug solenoid. You will find this bracket also in my store.
