ATF color looks good.
I did not apply the sniff test.
I dont know if it was ever changed. Mileage is 69K.
I took it to my mechanic yesterday. He pulled P0720 Output Speed Sensor, and P0841 TFP Sensor Switch. He referred me to his Transmission guy. It goes in Monday. I asked...Should I wear a diaper when I go there?....He said....Well, no-o-o-o, probably not.
So far around town, its OK under 30mph. The CLUNKS were at 55mph and then at 40.
When I told my mechanic that I saw nothing in the owners maintenance schedule about changing ATF, he said it is not our grandfathers ATF, and it costs $16 per Qt. (hawaii). Usually it never needs changing...*they say*...he told me.
Googling those codes....transmissionrepaircostguide .com says:
P0720. The output shaft speed sensor is located nearest the drive axle, and is used by the ECU to monitor the speed/RPM of the transmission output shaft. A P0720 diagnostic trouble code gets stored when the data coming from the OSS sensor doesn’t fall within the ECU’s preprogrammed parameters.
P0841. An automatic transmission needs a certain amount of hydraulic pressure in order to move gears around and propel you down the road. A P0841 DTC means that the transmission fluid pressure sensor which monitors the hydraulic pressure inside of the transmission is not performing according to the preset parameters.
