200 lb worth of transmission This honker is BIG! Nearly as big as an Allison.

Do a little reading first before drooling too hard. The 6L80E has no bands, just clutches. Shifting from one gear to another involves releasing one clutch while simultaneously engaging another clutch. All the timing is done by electronics.
It sounds wonderfully complicated to me.

BUT, it can be done! You may just not like the way it has to be done. http://www.zerogravityperformance.com/pr...0e-6l90e-6l50e/
