All of a sudden (this wasn't happening 3 days ago) when my trans shifts from 3 to 4 the revs drop and then jump a couple hundred RPM and then level off. It kind of feels like a firm quick shift when this happens. But not like a tire barking 1-2.

I have used HPtuners to decrease my shift durations (around .2) and shift points have been modified as well.

Is this a sign of the 3-4 pack going bad?

Trans temps are always right around 180
Fluid changed more often than it needs to be
TCI deep cast pan
Dex fluid

Does it happen when you are running around 60 MPH? I am having a similar problem and from what I can find out it leads me to think that the TCC solenoid (Transmission Converter Clutch solenoid)is bad or something related to it.

This happened to me about a year ago, it was barley making 2-3 3-4 shifts at wot w/o hitting the revv limiter as it would shift really slow. I reset my computer and it worked fine after that, never has happened again.

It happens to me in between 35-40mph.

I have bounced off the limiter on the 2-3 during WOT. This might be due to my moving shift points around. The trans sometimes shifts around 100-200 rpm after I want it too for some reason.

Have you had your transmission built up?
