I jus got my sct Livewire back from gettin custom tunes put on it by IDP! The tunes are great! Since I'm new to all this stuff I'm wondering about the shifting aspect... From what I've read and heard you want firm shifting, this is what will make a tranny last longer. But how do I know what's too firm?? I'm used to the stock shifting for 4+ years so I am hesitant. Can anyone provide some input for me?

 

I dont have a sct, but my H & S XRT PRO tuner has transmission tuning, & your truck will learn your new driving style. After a while you'll get used to your tranny shifting harder.

 

I have I think 5 or 6 transmission tunes, one is a race and one is soft, the others are firm early lock or stock lock of delay lock I think. So your sayin the tranny will kinda learn my new style and smooth out a little? How do I know if the shift is too firm? I don't wanna make my tranny go out quicker because of a hard shift. I am new to all this performance stuff I feel like an idiot but you gotta start somewhere

 

First, retrain your transmission by:

(1) Go from 0mph to 80mph with 1/4 throttle then come to a complete stop.
(2) Go from 0mph to 80mph with 1/2 throttle then come to a complete stop.
(3) Go from 0mph to 80mph with full throttle then come to a complete stop.

Don't be alarmed with hard or erratic shifts while performing the transmission retrain process because it's normal. Those three steps will retrain the transmission on the added HP's. After the previous three steps just drive how you normally drive and the adaptive learning of your transmission will figure out the rest.

 

Alright man thanks for your help, I appreciate it! I'm jus now learnin all this stuff haha

 

I know how you feel, Jake, I just bought my first diesel last summer and had to learn all this on the fly as well. When I had the DPF and EGR systems explained to me my first thought was: "The EPA (government) are complete idiots!"

 

Exactly my thoughts man, settin in their suit and tie tryin to make decisions that ain't worth makin. What kind truck you runnin? And what tunes ya got? I'm lookin into the looney street from Vivian jus to try it out. I already have IDP tune package, im likin them

 

I'm running the H&S XRT Pro and mainly run in the Mild 250HP tune. I also have my shift schedule at medium and overfueling at 3 which is also medium. I retrained my tranny in the HD (Hot Damn) 300HP tune as was recommended by H&S. That tune was a bit much for me.

 

I understand that, I'm conservative a little myself. I ain't runnin the big boy tunes haha

 

Jake, my truck is a 2008 F350 Crew Cab Lariat (not dually).
