Ok guys I'm gonna have some more log files coming. I hooked up the TCC and drove down to sd (400 miles or so). With the TCC in place the car ran good for the most part very steady rpm, but there was one issue that got pretty bad. Low RPM under load (2100-1500) the car would "shutter" really bad. Think, driving on the freeway stuck behind a semi going up hill. Typically I could manually down shift but sometimes the shutter would still follow. Also when it when in and out of TCC you can feel the car surge. Thoughts? My battery (laptop) died so I lost the log where I had it captured but one of the things I noticed is normally my LTrem would be very slow to move it took an hour to go from 118 to 121, but when the car was shuttering they would be flying all over the place. Another thing I noticed is that it will only happen if the car is at operating temperature for sometime. It typically has to be in closed loop for around 5-10 mins before it will start to "shutter" or if the car has been sitting for a few hours I can drive up to 30-45mins before it appears.

Thanks again for all the help. I'll post the logs I do have once I can get them off my lap top and online.
