Over the winter, I had my 6L80 out for other work. I installed a yank 3200 which I love. Long story short, I tore down, inspected, and installed a Transgo tow n go shift kit, friction kit,
and a Sonnax piston kit. This was the first 6L80 that I've ever worked on, but I was a transmission rebuilder in a previous career, so I felt confident in taking this on.I couldn't be happier with the stall and the shift quality. Definitely doable, but easy to screw up.Not sure what you're asking but yes it's worth it to firm up the hard throttle upshifts.

Yup! This was the type of response I was looking for. I am also doing a 3200 converter single disk. I already have a tune but might as well upgrade the trans while it’s out.
I haven’t torn into a trans, but my buddy does transmissions at my local dealer so I’m lucky there.
Dealership friend? Definitely do it.
I'll just share what I I think are key points.
Transgo and Sonnax are the real deal. Factory calibration of the pressure regulator and TCC, are the root causes of this unit being less than optimal for performance use.
These issues are addressed in the Transgo kit. Along with other excellent info.
Now trans shifts smoothly at light throttle, bangs at full throttle, and doesn't fall flat at low RPMs. The factory converter would only stall up to 1100 rpm. Now its about 2k. Perfect IMO.
I believe that it's a stout unit that I would prefer over the 8L or 4L. The gear ratios are perfect IMO.
BUT,
You will need to install a serious trans cooler, which is a lot of work to do right.
I was curious how much hotter it would run and the answer was, much hotter. First 60 degree day in Seattle, trans hit 225 in mild driving.
After replacing fog lamp with cooler/fan, never gets above 200.
Do it!
