However how does the triptronic gearbox go. Does it down and upshift quickly and cleanly. Are you happy with it so far. I am seriously thinking about a 6 speed triptronic box. If only the one in my XF Jag would fit.

Thanks Bruce,
My 'Drive Around' is a current model HSV Grange with an LS2 and 6 speed Tiptronic. It is a fabulous car and really performs despite its weight of almost 1900 kgs. I thought, "How good would it be to have this setup in a Cobra?" My RMC weighs 700 kgs less than the HSV.
While I haven't really given it to the Cobra yet, as she only has a little over 200 k's on the clock and running around on Unreg. permits, I have, on occasions, stepped on the HSV so I can only comment on its performance.
It actually launches off the line really well. First and second are quite short, but then it gets it's legs when it reached third. The Torque Converter copes easily with a 4,500 rpm launch which I normally do in 'Drive' then click over to Tiptronic for the remainder of the run.
Just google '6L80E Transmission' and you can get the ratios.
When driven normally, I defy anyone to pick the gear changes.
The Cobra however, created a few problems. I searched everywhere, including the USA for someone who had installed a 6L80E into a Cobra... No Result, so it looks like I have the only one that I know of.
The problems arrived by virtue of the security systems which are normally built into vehicles like my HSV. The 6L80E Transmission has its own ECU which runs through everywhere including the sound system, ignition, air bags, ESC, security system etc etc. What we had to do was convince the Transmission that these items were present on the car, even though they weren't, a huge electronics nightmare. I was wishing at this stage that I would have installed a 6 speed manual.
Jimmy and Justin from Sideshow's Performance Tuning in Sydney came to the party and designed a series of micro switches to trick the transmission into believing that it had all those things mentioned earlier.
Everything seems to be workling fine at the moment, but only time will tell. Let me get some race days under my belt and a few thousand k's and ask me then.
Hope this helped you out.
Baz
