TD5 auto box problems

Hi I'm Danny, I have a 2000 TD5 auto the problem I have is if I start off going uphill once I get to 2500 revs the revs increase very quickly but the car slows down (if it was a manual it would be just like the clutch sticking. I have noticed the waste gate control valve has been bypassed but the ends of the vacuum pipes have not been plugged any help would be greatly appreciated
