Actually, why I pointed out the ex-HG 27 B2 E4 KUBs in the list
was because, I've the thinking that those KUBs that were ex-perm HG
27 had their gearbox "tuned" somewhat differently compared to the
other E4 KUBs you see running around on the roads.
The rev limiters on those ex-HG 27 KUBs don't cut in that early as
the others, so therefore they can engage "kickdown mode" more
easily than the other E4 KUBs without the usual jerkiness. It's as
though HG has done something specifically back to those KUBs back
then when they were perm HG 27 and played with their ECU mapping or
something.
Purposely use these special 27 perm KUBs, because the gearbox is
smoother... But, I seriously think that the other KUBs from other
depots should have their gearboxes tuned like these 27 perm KUBs,
then no need so much depot transfers...
