3 tranny trouble codes,what do they mean??

[speedo1]

98 EB v-8 AWD. Only had this for about 3 months. Last Saturday, out of the blue, my OD light started flashing intermintantly. I'm a genius, ahh a code,LOL. My friend scanned it: P0712,P0713, and P1783. Other than the codes, runs and appears to shift fine, no slip, no flair, etc. Now, it hasn't happened since.. justthat one afternoon. Am I good? I know the codes are temp. sensors low, high, etc. Could it be a faulty sensor? Any tranny guru help appreciated. I can't afford a tranny!! BTW, fluid up to level, pink, doesn't smell burnt. Thanks

As you said, all 3 codes are related to the Trans Temp Sensor. It may be a problem with the sensor or the wiring going to the sensor. I would check the wiring harness leading from the PCM (computer located at the passenger side firewall, engine side) to the transmission and look for any damage to the harness. If not, then it is probably a sensor problem since your fluid looks good so far.
