I flushed the fluid first thing, no change. I did check for codes even if the CEL wasn't on. No codes. The TSS should set a hard code, but this is a Ford, and they are notorious for not setting. The ECT was mentioned, too. I am scanning with a Vtronix Mastertech and I can follow the data stream. The ect is reading correctly. However, I have not had someone drive the car at speed with the scanner hooked up to catch it in the act. I will try that this weekend and get a snapshot of the data stream when acting up. Thanks for the tip! Any suggestions are helpful.
