Hi, I’m new here so hope this is the right place to post.
I just bought an XKR 4.2 S, probably should have done a more thorough test drive, but I’ve got it now, so…
When it downshifts from 5 to 4 there’s a harsh jolt from the transmission, it does this on a trailing throttle and kickdown. It doesn’t do it on any other downshift or on upshifts. It’s also less harsh, sometimes barely noticeable if I’m braking. It happens at 35-40mph.
Is it a fluid or filter problem, or more serious, and am I doing any damage driving it, everything else is fine!
