L8T Swap - 2019 T1 Sierra w/ L84 + 8 speed


Recommended Posts

I've been planning on replacing my L84 when she gets up there in miles, was going to upgrade to the L87.  Now I'm seeing this L8T crate from GM and I'd love to make this work when I do the swap.

I know the L87 is close to plug/play from the L84 since there are separate transmission controllers, but would the L8T be a similar situation?  Hoping so, would be a cool swap to do and document.
