I have a 1998 Catera. After driving for about 10 miles the transmission warning light on the dash will come on and all the lights on the shift counsel next to the PRNDL letters will also light up. Occasionally the check engine light will light up, but not every time. When this happens the car will start in 3rd gear(from a stop), but once it gets above 20 mph it will drive normally. If you turn the key off and restart the car, the lights are all off and the transmission shifts normally. The lights will come on again at some point, but after it has done it once you just don't know when it will do it again. Seems to happen after the car warms up. I read the codes and there are 2. 1 is P0713 - Trans temp sensor circuit signal high and 2- P0705 Trans range sensor circuit (PRNDL circuit). I had the car at a transmission shop and they replaced the neutral safety switch. Seemed fine for a couple months (don't drive this car much) but then started acting up again. Could not get any satisfaction from the transmission guy. He is passing the problem off now on the transmission computer. Don't want to throw a whole lot more money into this car, there are other issues, but I think I should start here. Any suggestions would be appreciated. Thank-you.
