ATF and Transmission Filter Change Procedures (45k PDF)

Ford (213k PDF) GM and Chrysler (179k PDF) These guides are used to identify which transmission is in a vehicle; some vehicles have three automatic transmissions possible. These guides are also published in the AMSOIL G-194 Oil & Air Filter Application Guide, on pages 247 and 248.
