Glad I found this thread again, thanks for the info here guys. I have a very similar problem with my truck that I also assumed to be some sort of TCC problem, but I recently had my transmission completely rebuilt and this didn't solve it. I will be looking into ignition issues now, great to know where to start!
Thank you for posting we keep in touch
My mechanic is going nut with this issue (remember : ignition and tranny brand new) but still a very short a suddlently shock/cutoff ONLY on OVERDRIVE at 55 mph and steady speed.
