Some background on the update:
The main issue was jumping out of 2nd gear at Wide Open throttle.
The update kit consisted of many parts, fixing many problems, including a revised 2nd gear dog ring to fix the popping out of 2nd.
It applied to Not just silver engines, but up to a certain VIN which I do not remember.
I had the Trans update done way back in 09 on my 08 standard.
Triumph did mine under warranty, but many folks got it done for free out of warranty.
My symptoms were: WOT in 1st, quick shift to 2nd, back on the throttle, BANG pop out of 2nd into neutral.
Many folks also got stonewalled by dealers that had no clue and wouldn't acknowledge the problem.
Others got the parts free but paid labor.
Many riders with bikes in the VIN range also reported no jump out of 2nd at all.
As time went on, the number of freebies diminished.
And the cost of the kit has now increased to the parts' combined list price, not sure, like $1200 to $2000.
As stated above, unless the bike jumps out of 2nd at WOT, forget about it, since the cost with labor is big bucks.
