First post- New owner of a 14' 3500. It has 58k on it.

It has shift flare in 3-4 and 4-5.

The other issue I had was with reverse.

It's only happened once on a cold start up. I park on an incline.

Could not get it into reverse. Sucker was stuck. When I finally got into reverse I made it half way out of the driveway and it fell into neutral? Gear selector still said reverse though. Put it drive then back to reverse and then it was fine.

Any thoughts?

As for the flare shifting.

Will a valve body and tuning fix that?

I was looking into Revmax and DRD.

Thanks guys.
