Re: CRD bog down at 3000 rpm
My Jeep had a similar problem about a year ago. The tranny won't upshift at times. basically staying at one gear. had to pull over shut it down and restart. Replace the speed sensing unit (electrohydraulic unit) in the tranny. It work great after that. Be careful different unit for '07 & '08 models. Look into it....hope it helps.
