6L80 to 10L90 swap? Seeking insight on a 10 speed transmission upgrade

buckwild27 · Dec 16, 2024

I really want to know how it's going after the swap, as far as the transmission holding up. I see a lot of people complaining about 10 speed failures still. I would like to do this swap in my work truck because it will never pull a trailer, or have to work hard.

I’m curious too. This seems so tempting… how integrated is it too? Does the manual shift show 10 speeds now?

Is the trans running off old architecture so that performance tunes are applicable?

I believe the gear display will only show what the original trans gears had. I believe that was on the website for this conversion.
