6l80e shift issues when tires break loose?

Do any of you notice the transmission shifting weird (acts confused) when your tires break traction (traction control off)? I heard the tire spin throws off the traction control module causing it to shift weird. Mine sounds like it bounces off the rev limiter before it shifts. Seems fine when it hooks (which is never). Just wondering if I'm the only one having this issue?

Same thing mine does when I'm in 2wd. Bounces off rev limiter for a quick second then shifts. Just tire spin is all.

When I had the 6l80 in my truck I had to pull all the abs fuses to get the trans and traction control be happy. With the 4l80 Im going to try and tune the ecm to not close the throttle.
