You could always get a hold of a 8 Speed 8L90 from a newer Sierra, Silverado, Yukon, or Tahoe. There is also the 10 speed transmission from the new Camaro ZL1 and Corvette.

P.S. don't buy an 8 speed, the relearn process for the clutch packs/transmission adapts is horrible to do. There have also been some transmissions that have failed completely.

but will the jz auto take daily abuse from roughly 550hp ?
tranny modding info would b online somewhere I'd imagine. Boosted IS300, SC300, GS300, Supra, etc
Saw a buddy fiddle with his aristo auto. Dunno where he got the mod info.
He said he "bumped up the line pressure", and showed me two switches he used for shifting(via solenoids iirc)
With a SAFC and precision 62, brake stand street launch, really moved out. Tire smoke on the run
He raced it on drag radials & beat on it. They gotta b pretty stout, especially if moded 'properly'
Side by side, the tranny was barely bigger than my rwd corolla 4spd auto surprisingly... just barely
GM4L60E? look lked a monster by comparison
