go outside and look at the two new tires on your kia then drive it and feel how smooth and non pulling it is then come back to your keyboard and stop talking shit
the servos crack and stick they run low factory line pressure and the stock clutches and steels are junk if your going to beat on it much I'd go for a full performance rebuild
the best way to check is to evac and recharge the system and see if it still has the same symptoms if not it was probably just low if it continues to run funny you may need to change the dryer and the orfice tube
