Was the transfer case oil level correct during your last
15,000 mile change?

I have a 2006 Xtrail with a 5 speed manual transmission. When I accelerate
from a standing start, I find that the engine takes a long time to slow down
when I take my foot off the gas while shifting from first gear to second
gear. This makes for a rough gear change because the engine is revving too
fast for second gear at the moment the clutch is let out. It is also hard on
the synchromesh. Is there any way to fix this problem other than
accelerating and changing gears very slowly? My mechanic says that this is
all set up in the computer and there is no way to change it.

Might try double clutching. Shift out of first, let the clutch out,
push the clutch back in and shift to second gear as you would normally
do. Used to work in the good old days.
