Vehicle shuttering between 40mph-70mph, please help!

[DenverDude2002]

Ive heard about this before, but need some help isolating the problem. Hasn't done it until today, with the cruise control on, a shuttering sensation throughout the drive line lasting for maybe 1/2-1 second first going between 60-70 with the cruise control on, then doing 40 on my way home. I cant tell if the cruise control is related to the issue or not. Both times i was about 15 minutes into driving time. It has me worried at the car only has 67k on it

thanks in advance!

I'm just going to guess and say torque converter shutter... Mine does it some times at about a steady 45..

My buddy had what sounds like the same problem check the u-joints ballpark guess but it could be a first sign of it going bad.

Changed the tranny fluid yet?

Mine does it too. I changed the fluid and filter in the trans and it got stopped, but is starting to come back 3 months later. I'm thinking I need to do it again and drain the torque converter this time to change more fluid. Mine only does it now intermittently when going into overdrive. Try turning you OD off. If the shutter changes, it's probably in the trans. If it's exactly the same, check the Ujoints and other hard parts.
