New light & medium duty newsE-series, F53, and F59 are all still using the 6 speed auto with 7.3 V8 so I figure it is due to customer preference.
Also, maybe there is no room in there for the 10 speed? Or it will involve some structure change that won't be cost effective?Fri, 05 Jun 2020 17:17:13 +0000
