spartan 250 trans help

[smokeless_6.4]

ok, i pulled the trigger and went from the 210 to the 250 tune on my truck with under 4k miles on it. i did the tranny relearn 2 different times. after the first relearn shifting was better of course but the 2nd to 3rd gear shifts harder than the rest of the gears by far. so 500 miles later i do the 2nd relearn with no luck still the hard shift from 2nd to 3rd. When i do the 4x4 high launch to 70 everything is perfect. but as soon as i finish the relearn i feel it. and seems like when i punch it to get into traffic it hesitates not sure if its the converter or not please help, thanks in advance.

The 2-3 shift is always the hardest shift in these transmissions with tuning. I am no tranny expert, so I can't tell you why. Only thing I can figure is that higher pressure is needed when that gear engages.

My truck does the same thing i really do not know why but i have a few thousand miles on it and its still holding up.

If i drive it Slightily more agressive it seems to shift alot better then then when I feather it I dont know why???? I hope someone can figure this out it have been bothering me for months now!

I am about to switch to the 250 soon too and will need to do the tranny relearn. Only thing is... I dont know how to do the relearn?? Is there an option on the dasdaq or do you just do it? Noob question for sure, but a needed answer none the less.

A tranny relearn is just you going out and driving the truck in a way to get the tranny to learn consistency. Go out and do three 0-60 passes at 1/2 throttle and three 0-60 pass at WOT. That should be plenty with the 250 tune and stock TCM.

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.


I think this is the best way to do it i got this from the spartan web site.... am i wrong is there a better way to do it?

That is the best way to do it for those that have our TCM. The stock TCM doesn't need that extensive of a relearn. The one I posted above is plenty for the stock TCM.

Do you have to re load the tune to do the re-learn or can you do it after its already been driving a few thousand miles?

I know im a noobie dont want to bother ya bud!
