Before the output and input sensor and map sensor were changed the codes were p0722 and p1107. Any chance you can be the trans fluid sensor I seen a guy online have almost the exact same symptoms and the tech told him it was the trans fluid sensor does that make sense

A code does not necessarily mean a bad sensor. Any loose connections with wiring, broken wires or a bad PCM can be the cause.

P0722 - Output Speed Sensor Circuit, no signal.
P1107 - MAP sensor short or intermittent low voltage.

For both problems it could be the wirings that is at fault. Any loose or contaminated connections can cause that.

After replacement of the sensors, are the trouble codes the same?

The MAP sensor should not affect the transmission shifting but can cause erratig idling, stalling or difficult starting.

Recheck the sensor and its connector. Ensure the wires are not broken as they can be brittle and removal installation can break.

I had a technician do it is there anyway I can look under the truck to see where the sensor and wiring is, or is it too hard to get to , and I need to take it to a tech. Again

It is not too difficult to get to but you might need to remove the battery and air cleaner.
