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?

Modern trans oils last a LOT longer than years past. If it is in your 2002 you may want to have that checked out. Many modern vehicles (like Toyotas) have sealed transmissions even because the oil is so good.
