Every tune.

I talked to some guys on OutlawPSD.com and I'm not the only one.

What do you mean you're fighting a shift? Shifting too late or too soon?

I am curious also...
Perhaps the shift you are referring to is too soft or too hard compared to the other gears? If so, then it might be possible that you are experiencing the TC lock since on my truck it feels like a harder "shift" compared to the changes between real gears. However, my truck has an upgraded TC so I figure that might be the reason for the extra firmness when it locks up. I wonder what it's supposed to feel like with a stock TC???

When I have AE connected on a stock truck...I noticed the TC solenoid appears to be modulated so it might not receive full line pressure immediately but more of a two step lock up sequence. (or at least it seems that way from the live data I've seen...)

At any rate, when I first installed my PHX chip I noticed the TC lockup and thought it was a bit too aggressive. However, it didn't take long to become accustomed to it and now it's a non issue. Seems hardly noticeable now unless I revert back to my previously driving style. I let my wife drive my truck just to see if she would notice anything and she didn't have any complaints...her only comment was that my truck seems like it has a lot more power than her truck so I was happy with that report.

Thanks for the report Trey, I was very curious to hear from someone who had tried both tuners in the real world.

I just noticed you don't have gauged...next purchase? I'm assuming your transmission is stock as well?

No problems with my shifts. Maybe explain the issue a little better and maybe Cody will chime in. I guess you can say what ever you want on the outlawpsd.com. Who owns that site? The black background makes it kind of hard to read.

By "fighting" I meant fighting with whether I want to send it back to have it fixed.

What happens is when it goes to shift (or perhaps its the TC.. idk) it feels like it engages a clutch and waits to catch the next gear. It takes about .5-1 second and then the next gear will engage, but when it catches it kicks.

I will try to get a video of it.

I think I know what you're talking about. It's like the transmissions has stored up all the extra power from the engine, then slams into gear? That's the way my stock transmission acted with the TS tunes before I burned it up and upgraded it. The stock torque converter hardly covers stock engine output, IIRC.

Always look forward to your videos...

Kinda does sound like you are feeling the TC attempting to lock. If so, I believe that can be addressed in the calibrations.
Maybe Cody will see this thread and offer up his thoughts...
If possible, perhaps you could begin recording from a dead stop and narrate at each shift point while guesstimating how much throttle you have into it. (might help with the solution finding process...)

I will try to do that. It doesnt ALWAYS do it so I have to drive around trying to get it to do it so I can try to narrow down when it happens.

I dont think the trans or TC is bad, they were rebuilt like 20k miles ago.

I don't think the trans is bad either. However, you bring up a good point. When the trans was rebuilt, did it receive any modifications? Something simple like drilling out a few holes in the VB plate would make a difference in line pressure and potentially cause the symptom you are describing.
