Aisin Transmission Tuning

[Harizon]

So it appears that the Aisin transmission can finally be tuned, as PPEI offers tuning for the AS69RC in the 4th Gen trucks. Does anyone with an Aisin have any experience with this? I’m looking at a 2014 3500 with the Aisin so I want to know if this would be worth it.

All I will say is to be very careful

Too soon to tell. And I like my Aisin as is.
But is a 2014 HO worth it, could be depends on condition and price.

I really don’t see a reason to tune the aisin. Just don’t try to put crazy power in front of it. We have a 2015 3500 with the Aisin and we have 230,000 miles and still going strong
