trans fault popped up on my truck last night then went away. It came up again this morning then went away again. My truck seams to be shifting and running good but this keep popping up. Anyone have any idea what could be the problem?

 

Has the fluid level been checked.. last time it was serviced ? How many miles on it ? you got to give us info or all you will get is a Guess...

 

Fluid level is good, there is 89,000 miles on the truck, have not changed the trans fluid yet.

 

P0712 transmission temperature sensor "A" low circuit
