Does it take time for the trans to relearn after installing spartan tuner

[firefighter4]

I just installed a spartan tuner,afe full exhaust, and s&b intake today and wow! This thing really moves. My only quiestion is will the shifting of the transmission smooth out. It seems to shift out really hard under normal driving but smoother when I have it to the floor. I have only put about 20 miles on it so far.Does it take the trans a while to relearn. I have it set on the 250 tune.

if its like h&s yess it will, it needs just to get an angle from 0 to 60 form different throttle percentages., so basically just give it time

[eric.davis]

give it a day of driving if you drive more than 100 in a day or a couple of days but usually about 100 miles is when the shifting has tamed down. but they still will be firm so the trans doesn't slip due to the tuning increasing the line pressure

TCM Relearn Process

1.) From a stop, accelerate the vehicle to 55-60 mph at approximately 1/4 throttle. DO THIS TWICE.
2.) From a stop, accelerate the vehicle to 65-70 mph at approximately 1/2 throttle. DO THIS TWICE.
3.) From a stop, accelerate the vehicle to 70 mph at approximately 3/4 throttle. DO THIS TWICE.
4.) From a 40 mph roll, press the accelerator to the floorboard quickly (forcing the truck to downshift) and accelerate to around 75 mph.
5.) From a stop, acclerate to 75 mph at wide open throttle (press the accelator to the floor immediately). DO THIS 2-3 TIMES.

this is for the spartan tcm not the stock

You should do it whether you have the tcm or not on the higher tunes.

I JUST DID THE TRANS RELEARN STEP FOR STEP AND IT STILL DOESNT SEEM TO SHIFT RIGHT. IT SHIFTS HARD BUT NOT QUICK. ALMOST LIKE A DOUBLE SHIFT OR SHIFTS TWICE WHEN GOES INTO GEAR.(IF THAT MAKES ANY SENSE) I GUESS I WILL KEEP DRIVING IT AND SEE WHAT HAPPENS. I LOVE THE POWER IT MAKES THOUGH.

Try doing it backsides. Sounds funny but mine shifted best after i wot'd it on a open road. Got to about 70. Then went back on a main road with stop and go. Headed back to the shop and it seemed good. Idont know, just a thought

It's my understanding that you should do the trans relearn no matter which TCM you have. Even changing from one tune to another you should do the trans relearn. Just what I remember. YMMV
