I have a mazda 3 2008, I repair the transmission, changes the fluid, put a new solenoid sensor and the code still come on,

when I drive the car for a couple of miles the car wont shift from 3rd to 4th gear and at that exactly moment when is running for couple of miles the AT light will come on and will send me that code P0762

someone can tell me what else it could be the problem if some connection or cable or something else?

 

Most likely the valve in the valvebody is sticking. The trans will have to come out and be taken apart to fix it so you might as well overhaul it. There are some additives that sometimes work. Lucas has a good one.

 

I know this thread is dead but did you ever come up with a solution? I'm having the same issue with my 2005 ):
