So almost to 71k on the CRD now, and the transmission is acting a little funkyer all the time. Sometimes after you first start it and put it into reverse it will take 6-7 secs to engage. Other times a shift will just feel "weird".

Not having had any issues in the past I always kinda just glossed over other peoples problems, though most of those I seem to remember being "shudder" related. I have never gotten any shudder out of it so I feel like the problem is not TC related.

71k on a 2005 without the F37, very minor towing use.

Thoughts? I think a fluid and filter change is the first thing in order, however if that doesn't improve anything I am not sure what else to try except for a pump replacement.

x2 on filters. The anti-drainback valve on the screw on filter is a weak point in my opinion.
