Buick LeSabre Never-ending Ignition Coil Problems

Re Ignition Control Module;
There’s a lot of long hills around here and forgetting to move out of second gear will invariably burn out the control module after forty miles or so. Which I have done a couple of times. One must CLEAN the module and seat and apply lots of new heat sink compound. Not something mechanics usually have around. Heat is the enemy. I keep a couple of spare control modules from the junk yard. ~$35 ea.
