This is for my 2005 with 6.0 but has anyone had any experience with the 3-4 shift being harsh? I expect the shift to be harsher under a situation such as WOT and letting off the throttle (letting it shift up to 4) but if i take off from a stop and accelerate with 25-50% throttle till it wants to shift to 4 it usually is harsh. warmed up and cold. It still has the TAP values from my step dad owning it (transmission adaptive pressures) and I was going to throw my scan tool on it and clear it so it learns my throttle usage. Maybe he had a lead foot? all other shifts appear fine including downshifts while stabbing the throttle (such as to pass)
I was wondering if anyone with 4l80e experience have had this or can say if its characteristic? Since gmt400 came with 4l80e's in 1991 I put it here lol
Its a 2005 2500hd with 4l80e, lg4(6.0), and np263hd transfer case, and 11.5" aam.
I have been driving it for about a month now and I havent reset the battery or the TAPs so thats why I mentioned I will try clearing them and see. it did have a recent trans service before it came to me (TAPs should be reset after trans service) I just wouldnt expect it to be such an aggressive shift especially with low throttle input. Lower than 25% seems to soften it but it takes a metaphorical minute to get to that speed at that throttle input
