hard shift into 4th

my transmission shifts fine from 1 to 3, but when it shifts from 3-4, it always shifts hard, really jerks hard if im goin up a hill and steppin on it a little..

and it seems to shift a lot smoother when I got like 3000-4000lbs on the truck it makes me think its more of a electronic issue??

other than that, theres no issues with the trannny, doesn't slip at all

any thoughts as to what it might be? im going to change the fluid and filter next couple of weeks...

thanks

I keep it on 75 for driving around, I just recently got the TS.

it shifted hard from 3-4 before I got the chip, when I installed it, it firmed up the shifts quite nicely, but it makes the 3-4 shift a little more noticable

Was going to say, when I put mine into the 100hp or 140hp settings the shift from 3-4 shakes the whole truck, not so much in the 40hp and 75hp.

before I got the chip it was only every once in a while, but it shook the whole truck like ur saying, after the chip its nowhere near as bad, but its almost everytime it shifts from 3-4... im just wondering if its something that needs to get fixed? a because it seems to shift a lot smoother when I got weight on it..

I just don't want to have tranny probs down the road if they could have been prevented

Maybe try shutting off your overdrive and trying it out and see if it clears up, that could narrow down the problem. Otherwise I am also kinda stumped, maybe someone else will chime in with some info. But a tranny fluid change definitely wont hurt anything and could fix the issue all together.
