In accessory for 10 sec, then off, then starting is to reset the throttle response

I reset the tranny programing and it seems to be a little better. Doesn't shudder as much or as bad as before. Maybe a programing issue, especially since some have had thier tranny replaced or rebuilt and the issue returned immediatley. I've always noticed if you give it more gas or let off the gas a little it stops immediatly, just as driving in sport/manual mode it doesn't do it at all. But still do not know what it it causing it..

Same issue with my 03 4.4i Sport too. More noticeable when engine is warm and with more weight in car. Have tried MAF cleaning and coolant flush but does not help. Only band-aid that works is putting it in Sport or go heavier on the pedal. Does anyone know which years the transmission software upgrade is available for and if it solves the problem?

My 2002 4.4 does EXACTLY what the op posted. I am going in today (for the third time) to get this resolved.
Here is my theory. ...... We all understand why wheels need balanced. And we all understand when they are not, they can get shakey, jerky, vibrate, (what ever yiu wanna call it) ONLY AT CERTIN SPEEDS. This is called "harmonic balance" the natural vibrations of an object spinning. NOW, our motors spin, and also have this same issue. At some rpm's our motor is very "harmonically balanced" and at other rpm's..... not so much. I believe that if the motor mounts were worn out, loose, ext... That this could give us this "shake" at a certin rpm. Two reasons. Those of use who have this issue... It's IDENTICAL to one another. PLUS have you notice that when this issue is happening, you can REV right past it? Typicly when a motor is running rough, and you add throttle, the motor struggles to "REV out of it". With this issue, I can REV out at any speed, slowly, quick or what ever. I will be with the Teck when my ride is up on the lift. This problem is over TODAY!!!!!!

The issue is line pressure is just a touch too low at that RPM/speed/gear. This is causing the hyd pressure on the clutch to insufficient and the clutchs are "kicking back". Teck told me a trany flush may fix this. Or a trany update may fix it but he stressed no guaranty. Othe possibility is the hyd valve block is scored and the valve body is hanging up causing what we feel. So to recap.... Could be fixed by a flush and a program upgrade total of $250. This is back up by issue instantly going away by switching into sport mode.
