No biggie there guy.

Luckily the aftermarket will build beefier parts.
Engine HP is not impressive and I'm guessing the gearbox torque reflects the torque converter multiplier.

It is a huge inertial change and what they have seen cause failures. They try to beef up the parts, but the bean counters have the final say. Luckily the aftermarket will build beefier parts.

The 4800 rpm is the ENGINE rpm (and converter input shaft rpm). The Tranny still drops to the lower rpm based upon the gears inside of it Also, the long shift extension likely adds some torque multiplication on the 1-2 upshift so more torque is actually being fed into the tranny where it has the biggest drop.
The higher stall also adds more stress at launch. The stock converter probably has an STR of less than 2.0. A good high stall unit will have an STR of greater than 2.0. Combined with higher input torque from the higher stall speed, it will put more stress on the tranny at launch.

Been since late july i think... Our track opens here in two weeks i think, so it shouldn't be too much longer... Tires are worse now, so times prolly won't get any better until i get my 9inch and start running drag radials! Wow buddy I like how those rims look!

Does anyone happen to have the Escalade A6 trannsmission physical specs? Since its a stand alone computer system that should make the swap pretty straight foward. That with the exception of the bellhousing, crossmember, and maybe a different length tq arm, but would be well worth it. Is the A6 triptronic style or is it still all mechanically controlled with the shift lever?

Verdad Gallardo The 6L80E was designed to fit where a 4L80E fits, it was meant as a replacement unit in newer vehicles ... and since those vehicles chassis were not going to change much at all, those were the design constraints for the 6L80E. The bellhousing is the same as an LSx and the length is the same as well. Yes, I believe it is capable of "tiptronic" (VW term, not GM) shifting.
