2-1 downshift flare then catches and 3-4 harsh shift sometimes

[THEFERMANATOR]

I've noriced on my ALLISON that when it does a 2-1 downshift whil I'm at idle and if I touch the throttel right when it begins to downshift it's like it goes into neutral and then catches. I notice it ht emost when I am turning into a parking lot or shopping plaza where there is a slight incline to the entrance and I am trying to ease up it slowly. Is this pretty much normal of all the ALLISON's? I ask because my grandfathers motorhome has a 3560 6 speed in it and his will do the same exact thing except his has a CUMMINS 8.3L mated to that is mechanically injected and will bang when it cathces because of no torque management on shifts.

Also I have noticed on my ALLISON in the BURB that when it does it's first 3-4 shift once it is warm after a re-start it will shift a bit rough and will be fine for every 3-4 shift after that. Is this a problem in the 01 OS, nature of the beast, or sound like I messed something up on my build? I did use 7 clutches in the C2 pack when I did the build and I didn't have a spring plate to go in it.

Yes it is normal with your set up. The wave plate would have taken out the harsh shift.

mine does the same, it used to bother me but now ive gotten used to it reving up and catching that i just feather the trottle till it hooks up and go on my way... although it hasnt really happened since i turned my mp8 down to about 10%, that seemed to fix allot of problems for me

The 3-4 I figured was normal with the 7 instead of 6 in the C2, and it only does it the first 3-4 shift on a warm re-start. The 2-1 flare can be planned and isn't that bad in mine, but I know my grandfathers motorhome is VIOLENT when it does it. Was wondering if there was anything that could be done to help it some in his motorhome as he has complained about it since he got it in 96, and he really complains about it now that he's over 80(or could be he's just looking for something to complain about).

and when its stacked and up above about 10% i have problems draining the rail, and it makes the truck very aggressive from about 1200 rpm to around 2300 so its quite hard to be accelerate when its up... but it does wonders when towing when i dont need to go WOT, but i need that low rpm torque
