Someone on RV.net wrote that the Aisin transmission was developed along side the Ally. Now I know they weren't designed together but is there any relationship at all between them?
General Motors sold Allison transmission in 2007 maybe that's why this venture broke up.
I have spoke to two reps form AISIN on the phone both very kind but could not answer my questions,,,, The one they did answer was the 69 can support 425hp @ 1200lbs TQ,
Too bad they didn't have the new Aisin 69, which is significantly beefed up compared to the 68 that was used in chassis cabs before 2013.
