So my new 2007 CL9 with barely 47000K on it seems to have a strange behaviour with holding onto revs (like it is not shifting down sometimes)
Like today, I am rolling down hill for about 150 meters @ about 65km, I let go off the accelerator and it feels like its still holding on @ just a little over 2000 RPM.

Other times I back off the accelerator on a straight and every now and then it doesn't want to shift down, still holding @ 2000rpm unless I tap the brakes or accelerator.

I didn't notice this behaviour from my 2003 CL9 I owned before???




I think a transmission flush in order but which of these is better given the are about the same price.

which of these specs is better
