Engine oil diesel rated 15/40 weight.
Transmission fluid , ATF Type III or IV unless the fluid has been changed to Transid ,I'll check the spelling . If the fluid has been changed in the last 3 years , this is Allison Transmissions new fluid.
My hydraulic pump system for power steering and rad fan , uses ATF Type III on my coach, if the fluid in your coach is red in color , that should be what you need there.
Correct spelling for the new fluid is " Transynd "
