Default shudder in cruise?

Generally in cruise. The tranny has a shudder once and a while when trying to maintain the set speed going up hill? New to the site. Any ideas would be great.

Thanks

How old are your plugs/wires?
Many torque converter lock up or cruise issues are ignition related.

Smile ok thanks I will check

Thanks for the fast reply. Plug wires are only one year old. Had something chew a couple into pieces and the plugs are about 35,000 to 40,000 miles on them. What is the best brand of plugs to use on the 3800 supercharged?

I will also check the motor mounts. Again thanks for the fast reply.

I use autolites, others use NKG. Both work great. Make sure your wires for #4 and #6 are not touching the wire for teh O2 sensor wire. Also make sure there are no grounded wires.

Here is the mount to check. My bolt fell out and I didn't even know it had happened until I reached down and grabbed it. It'* in the front drivers side.

Check your tranny mounts too: I had the same shudder in mine w/Cruise and I'm getting a tranny mount replace on Monday....
