Holy crap! Ill keep my ear out for that issue. Is it year related or in general?

Made it sound like in general..

Oh wow. Ok

I ran proven on my 2014 and again on my current 2015. Zero issues with the trans in either. Shifting is spot on. Much much much better than the unknown tunes my ‘15 came with. Trans now performs exactly like my 2014 did.

Maybe I’m just used to shit trans tuning??? [emoji23] doubt it, but if enough know it all facebook warriors complain about proven enough then they’ll drive down sales and make people think (that haven’t run them), that they’re junk. [emoji1787][emoji1787]

There is probably better out there. But I’m pleased on the 2 personal trucks I’ve ran them on. Power is spot on and show have the transmission manners.

Yeah, I have no experience with them so take it with a grain of salt.

All three of the dealers I spoke with in Canada recommended ***P instead due to more recent support and TCM issues.

I'd give Proven a try on my personal truck, but with how many issues this ones had I didn't want to chance it.

Trans shifting seems great on the few i have done. Definitely had to clear trans adaptive learning to smooth it out just like any other.

Recently did a '14, Proven removed the KAM reset option for some reason.

Did stock shift points with higher pressure, the trans is all over the place. It decided the other day not to shift out of 3rd, RPM's were screaming till I bumped it into manual and shifted into 4th.

Truck is on a stock tire so I thought stock shift points would be fine. Is the med shift points really that much better or recommended on a otherwise stock truck?
