Mobil Delvac Synthetic Transmission Fluid 50 - 35 lb. pail

Works great in my ram 3500 manual transmission

Was told it would work in an Allison 3060 but by the time I was able to get filters and change it I found out it was too heavy a grade and wasn't approved so lost a quart when noticed was thick like diff oil and had to flush it out of trans. Just an FYI if you're looking for synthetic for the big Allison.

Received Pail of oil in a timely Manor. Was as decribed

Good stuff!
