The manual trans only has one OD. The autos have 2. My options when I bought my truck. If I got the aisin with 4.88's, it would pretty much be identical if I got the manual with 4.10's. I opted for the auto and some days I regret it. But towing with the aisin and 4.88's is a dream when towing heavy.
