Since I can go from a long delay, almost like a slip at 60 deg, but a crisp shift at 61 deg; I can asume that the temp switch is working. I guess there is a problem in the line that is switched in at temps under 60 deg. I would need to locate that temperature controlled vacuum switch and determine which line that is. I've only found a 25 deg C vacuum switch for the EGR system so far...

Now, what would cause the delay, too much vacuum, or too little?
