    I have 4 2015 prostars automatic that have trouble braking. When trying to come to a stop the truck seems to keep going forward. Even with the brake pedal pressed the truck keeps leaching forward. I have gone as far as replacing the brakes along with brake valves and this continues. Could this be a transmission issue? Also at times the trash control light will come on. Could that be because of the airbags been over inflated as well?

    What would be the best course of action? Would it be a transmission issue? Meaning I would need to get the automatic transmission serviced or replaced?

    Could be a linkage issue, actuator might be weak, or it could actually be a loose spring rolling around in the clutch.

    Unlikely to be tranny itself.

    I suspect you have a bad brake switch so the trans doesn't know you are trying to stop to release the clutch. This would explain the clutch and traction control light issue.
