Hi, i have a 2004 ford ranger with a 4.0 sohc and a 5r55e automatic trans.
the other day my "od" (overdrive) light began to blink, the user manual says this means there is something wrong with the transmission. I know my cortex 1950 can retrieve error codes but i was wondering if it only retrieves codes from the engine and emissions systems or if it will retrieve transmission codes as well. I am hoping i can plug the cortex in tomorrow morning and hopefully retrieve any transmission error codes so I will know what is wrong before i go to a dealership so that i don't get the wool pulled over my eyes.

Can a cortex 1950 retrieve TRANSMISSION error codes on a 2004 ford ranger 4.0l auto?

thanks,
Jeff

The tuner does read transmission codes.

Just do not reprogram prior to reading. This will clear the codes.
