Welcome to 
Sounds like you're asking about the Exhaust Back Pressure Sensor. The Exhaust Back Pressure Valve (on the turbo) is used to help warm up the engine. (I keep mine unplugged - two-wire connector to the right of and under the turbo) I don't think it has anything to do with how the tranny shifts.
What code did they tell is being set?

This code is set when the EBP sensor malfunctions.
If you've cleaned the tube and where it's installed, I'm gonna take WAG and say you need a new EBP sensor.
