When to change Allison Transmission oil
It's been 53K miles and 10 yrs time on my present allison transmission " synthetic oil". Would you recommend an oil change due to the 10 yrs time?
Forum Discussion
I took mine to Allison Shop at 50K- and 10 year coach - where they took a sample of fluid and was advised that I should have the transmission re-sampled at 70K.
