If it is surging while climbing a hill or under hard acceleration, I would suspect a bad turbo control solenoid. When they start acting up like that they normally will not post a fault code unless the solenoid has completed failed and had no boost pressure. But as Jacobandnickolas has stated, verify if it is the engine or transmission. Try to gunnit on a straight ahead and see if it misses that way, if it does then diffinately replace that solenoid. It is clipped on next to the air cleaner box with 3 hoses. Just match the color codes, green, red, and yellow. If the engine light flashes then you have a misfire and should have a code posted in the engine control module. Keep us posted.
