Default 6L80 for a boosted 6.0L
new to the forum, Any great ideas along with using a 6L80 tranny on a twin turbo'd 6.0L? Use as stand alone or get a ecu to handle it also

There is a guy, member on this forum. (62naldie) that pushed his 6L80e around 800HP on a boosted full size 4 door truck setup on a stock PCM if im not mistaking. Tranny held up like a champ.

Thanxs for all the responses, I will cross that bridge when I get there. I have a built turbo 350 in my blown car, the extra gear should help

Do yourself a favor and use a 4L80 instead. Getting a 6L80 to hold up to big power is a challenge and costly, not to mention the controller issues.
This assuming you are not building a TT car to baby it.
