This truck doesn't warrant a 4L80E - it's essentially stock, but I'll try the Vette servo and see if it helps.
I found that this slips a lot more when it's warm. Right after start when the trans is in warm-up mode and holding gears a little longer, it shifts about how it should normally.
Which servo should I replace?

My mom's 03 Trailblazer with a 4L60E had a 2-3 slip/flare, so I swapped in a Corvette servo and now it shifts perfect(even after 30k miles). I later found out that a 2-3 slip/flare can be caused by damaged servo seals. So switching to a Corvette servo will give you firmer shifts and potentially fix your 2-3 shift issues. Win win.

Solved! Turns out it was the PCM. I swapped my stock PCM back into the truck and it shifts fine now. I don't know why or how it was causing the poor shifting, but it is working how it should now.

I have had red eagle clutches in mine for 8 months now. It's finally started to slip some. But it gets rode hard and put up wet most of the time. But certain people have better luck with some brands than other people do.

I couldn't tell you how many 60Es I been through. We tried everything in the tune with no luck. In the end the 80E will be the best choice if your making decent horsepower.
