i got quoted around $1100 for a manual conversion for my auII xr6.... no labour included obviously. i've gone from my t5 ea to a 4spd bf & later the 4spd au, both adaptive & can't shift kit. i don't mind the auto in the bf although it's missing a few cogs, the au however must be a manual.i wouldn't mind as much if it had a shift kit,and i'm anti-stall.
ea t5 is renown for being worste t5 ever & the only real problem i found with mine was that 1st gear was a bit of a joke but i could live with later model ratios. just for the sake of not hearing another auto falcon with louder than standard exhaust.....
