ok i have a 99 tiburon we just replaced the transmission for the second time and now the car has no power any one with an i dea of what could be wrong . no power to get on highway but it runs smooth no missing i have also replaced the cam sensor and plugs and wires the power band is very abnormal and slugish

 

are you sure you put the right trans in

 

may be the trany is bad. I had the same problem with mine and had to change it again 3x's, the dealer game me a bad trany that led to problems with the motor. Nobody is perfect and they could off make a mistake while assambleing it, or maybe you should check it again.
