Hi mate
had it done, put in the 3.45 and had the trans retuned. It hooks up fine although I did noticed at Sandown that speeds over 200km/h take longer to reach - I may have to hold 4th longer . I recall on my 2.92 diff easily hitting 217-220 on the front straight (can't remember the gear I was in). It definitely punches hard, but I think it loses at the very top - which is fine for the 1/4 mile and around the streets. Anyway, the auto rushes through 1-4 very quickly at normal driving. I wish i had a 7th gear now or maybe a manual.
