If the code is there, it means the problem is with the circuit but it also can mean a transmission internal fault but we usually start with the basics and easy part.

Why were the sensors replaced? Was there any previous codes prior to this?

Those codes came up and dealer decided they needed to be replaced about two weeks before they said I had a misfire and they took care of that

My suggestion is to recheck the connectors for the sensors and wiring thereabouts.

Is the MAP sensor code still present?

Checked map sensor code went away, was able to check wires felt and looked together and secure, any other suggestions what it could be

If the code comes back after driving, you would need to perform diagnosis such as checking the wires for continiuty to PCM. Ensure the sensor is correct.

Any chance the car is not reset right and the old habits are there from before the new installations or not possible

When a problem occurs, erasing the trouble codes would work. When vehicle is running again, the codes would come back if the trouble is still there. Did you erase the previous codes and retest?

Yes, and we drove it for about a half hour light came back on do you think I need to take it to a tech and have him go over the wiring 2 the speed output sensor

Yes, you should.

If nothing is found do you think it must be an internal transmission fault? If so is that a big project and real expensive any idea of ballpark cost would be appreciated
