Alright, guys need some advice before I do something crazy and drastic.

A bit of history this is my 3rd 6.7. Firsts was an 18 G56 that I deleted from 1200 miles and went threw a few clutch setups before I was happy, and it was tuned via Ray.

I loved that truck but sold it due to divorce.

Next was a 09 auto that also deleted and had H&S canned tunes.

Then decided to get back into a 4th Gen.

The current truck is 18 tradesmen full delete via Ray.

The truck has right at 45xxx miles.

Ok, here is my problem, I’m not too fond of how this truck shifts.

I have lived with it, but the shift strategy that these newer trans has is crap.

It’s to the point im even considering selling the truck and starting another build.

I have had many other diesel trucks of all brands, and I want this pig to shift as it should.

I want opinions here; if I go the built trans route, say Revmax 550, and the proper tuning via Ray, will this genuinely fix all the shift slushness and the torque converter slip, etc.?

I am open to ideas and suggestions.

I don’t plan on crazy power; I just deleted and stock fuel and charger.

Any help or suggestions would be greatly appreciated.
