Bad torque converter?

In the last week or so my 05 sport auto developed a shudder/front-end bounce off of idle...almost like you're driving over road strips for a few seconds. There's also a lot of vibration/rumbling sound through the floor pan/gas pedal/seat when accelerating along with power loss. When I let off the throttle and coast everything smoothes out like normal...it's really weird.

I'm thinking it's the TC but I wanna know what you guys think and if this is a common issue. All of these symptoms started at the same time. The motor mounts look good and so do the front/rear driveshaft u-joints. My jeep has 60k on her.

Hope you figure it out and it does not cost you. It sure does sound like a motor mount until you add in the power loss. I am assuming you had someone watch under the hood while you did the power brake thing. The only other thing I can think of would be to look under the chassis for loose bolts in the trans/Transfer case, and dry or tight driveshaft U Joints.

Step one is to drop the pan, change the filter, and do a full fluid flush. TC shudder feels just like driving over cattle crossings. You could have symptoms similar to yours if you are low on fluid, the filter is clogged, the fluid is black, the pump is on its way out, or the TC is on the way out. You can smell the fluid to see if its burnt, but I'd change it either way.

I removed the rear driveshaft today for shits and giggles. One of the bearing caps on the u-joint that connects to the diff flange is seized...dunno if this would cause my symptoms or not. Those caps are supposed to spin freely right? I'm going to put a new one in tomorrow hopefully that's what the problem is.

Woooohooooooo it was that u-joint!! Man i'm glad to be done with that issue...no more vibs or feeling like i'm dragging an anchor. It must've been binding up something fierce to cause that power loss...glad I caught it in time. Thanks for the suggestions guys.
