AVOS primarily developed for the XKR, which used a VERY robust mercedes 5-speed gearbox...
The twin screw equipped STR/XJR's running ZF 6HP's are few and far between, so its hard to draw any conclusions on how much power the 6HP will hold for us... Luckily very few venture into that territory...
But these builds to the ford 6r80's are very good development news for us! After watching that clip, I'm almost confident to tackle my next ZF overhaul...

Makes me wonder if I should do some upgrades for the TS, or just let it rock and see how she handles it stock. Hmmm.
gt42r, why do you say "luckily very few venture into that territory."?
I guess we will find out once the kit is released and on a few cars. I'm sold on it, tranny upgrade or not, I neeeeds it.

There are a couple running around now with my kit on a 6hp26 gearbox, remember the 4.2 XKR also uses the 6HP26 gearbox. I wouldn't say the Mercedes box is more robust than the 6hp26, both are pretty strong for street use, and on paper the 6hp26 is even capable to withstand more sustained torque then the Mercedes one.

Of course it's a very good development that the ford 6R80 is damn near identical, and thanks to being found in Mustangs, it's seeing a great deal of testing and aftermarket development we would have never have seen if it's use was isolated to just Jag use....
I say the MB 5-speed is very robust, because it is. It's used in MANY high hp applications, and many FAST benz's have been built around it... its proven itself... the ZF is clearly getting into that territory now too... I've never suggested the ZF is weak...
Yes the later XK's also used the 6HP26, but how many of those cars have a TS kit running on them? Seems like every AVOS TS kit i've seen on an XK was on the earlier body styles...
Yes, there are a few STR/XJR cars running the AVOS TS kits (2 or 3?), but we are still waiting on dyno numbers and for testing to wrap up... Because of the throttlebody limitations, they won't be able to put out the same max numbers as on the XK applications... Guess we will still have to wait and see on AVOS final numbers...
Then comes the value proposition... I think most owners of these STR/XJR cars, will balk at the price of a TS kit, plus you will likely want to upgrade the diff, maybe build the trans... for me personally, I start to wonder if I'm not better off looking at a 5.0L SC XF-R, XKR, XJR...
Even with a twin-screw 4.2, I don't think you'll outrun a intake/exhaust/pulley/tune 5.0L SC car... Sure, the KB 2.6LHO can support some very serious power, but so far the TS equipped jags are few and far between, and hardly any are making much over 500whp...
All this is why I stated "few will venture into that territory"...
