Let Me Know if You Have Allison Transmission Fluid Questions

Thanks for joining the forum and offering to help.

Last fall I replaced the Dexron in my 3000MH Allison with synthetic. It was done by the Freightliner RV chassis service center in Gaffney, SC. They used Mobil Delvac synthetic transmission fluid saying it met the Allison specs.

These folks service a lot of motorhomes so I am trusting they used the correct fluid.
