Trans fluid is new, but I will need to do the transfer case and rear diff next year. Regarding the shift sloppiness, it was all low speed part throttle applications that I experienced it. But that being said.. I've made so many different small changes to the air intake that I think the greatest influence on shift quality, is the air intake and how it affect the engine and power output.
I've had a cold air intake, stock air box with 6.0 litre seal, modified stock air box, and obviously the stock air intake. People really underestimate things like this since you're not going to see it on a dyno.
I like the stock box with 6.0 seal, just feels quick everywhere. It does nose over a bit up top, but not as bad as the stock one. Now i'm trying to figure out how much I want to open it up so that the top end is good without affecting off throttle top in.
This is all with my butt dyno, I could care less what a peice of paper says. It's all about what I feel its doing
