8 Speed

[t-cut]

What year was the 8 speed gear box introduced to the Jaguar XJ. I have a XJ 2012 with a 6 speed, can anyone shed any light on this please.

Hi, just a thought...

To the best iof your knowledge, is the 6.0 V12 the same origin XK block as the previous 5.3 V12 ?

I ask because the old 5.3 V12s used the old GM 3-spped automatic, and even with limited/no ECU controlò, I wonder if the newer 6:8speed boxes off the 6.0 V12 could be adapted...
