4L60E 2-3 flare

I have just over 160K on this and have performed regular fluid exchanges and filter changes at roughly 40K intervals. Trans shifts great except for 2-3, just curious if this could possibly be another issue or a clutch pack going bad. Heard of band release problems or soenoid issues but seems like just a regular slip.

Here's the vid I took and the flare comes right after 3400, I was going up a hill and kept on the gas to raise the shift point to highlight the flare more.

I did just perform a complete fluid exchange and replaced with Maxlife and a bottle of Lubegard red w/ filter.

All other shifts are good and TC lockup is quick as well, hard to tell in this vid as it happened right when I stopped filming.

All input appreciated.

At 160k miles on the trans , it is worn out.

the 3-4 clutch pack in this trans design has been a weak area since 1982
Dont worry how old you are... it is the mileage on your body that adds up.

Well, i've been toying with the idea of rebuilding myself, taking my time to do it right. Would need to rent or purchase some tools or just have my local shop clean the case and install the bushings etc.

I want to rebuild it to keep the shifts somewhat soft but not crazy soft like they are now or when new. I would like to build it to handle towing and possibly some HP....around 400 or maybe a little more.
I have rebuilt a few motors but with this trans the consensus is that it's not the ideal one to learn on...especially being my daily driver, I respect that. I surely don't want to dump $800 in parts to do it twice.

There is a shop near me that will swap one out for around $1650 with a 2yr/24K warranty and the dealer can swap a reman unit for $1800 w/ 3yr/100K warranty.

Only thing is neither is built for the higher HP but stronger than stock.

For those of you that wrench on these daily, are these prices fair or should I have it done to stronger specs somewhere else?

I am looking to possibly add forced induction and would not top 500 HP, peak is realistically around 400. I want to remove as many weak links as possible and do it right the first time.
