This is the cure for this issue: Either replace the temperature sensor, or (since it is my own car) jumper out the temp sensor. Here is what I discovered..... This car has the 2nd gear start. With this model, there is a temperature sensor located inside the side cover. It will cause the transmission to go into "limp-in" mode (1, 2, and 3 only) to allow the engine to run at a higher RPM to cool down. Well, there are 2 wires on the harness that are devoted to the temp sensor. I had another temp sensor from another transmission and I test it. It had 3K ohms resistance at room temp. I then added heat to it from a blow dryer. As the heat rose, the resistance went down to .9K ohms. So, I found a resistor that had 3K ohms resistance, cut the two wires on the outside harness and soldered it in place. This will tell the computer that the transmission is cool all the time. (it is my own car) I would not do this to a customer car (but it does work). Thanks for all your replies.
