I have an 06 Allison Trans 1000 in my coach I cant find my Allison manual! I would like to know when to change the trans fluid it came with transend ? I think the external filter changes every 25000 m...
Call manufacture with vin number. They should be able to tell you what transmission and oil you have. If you have transmission serial number Allison will be more than happy to help you. Chassis manufacture should also have information.
