722.6 C55 Trans harsh 1-2 shift WOT
Alright, so ive been having this problem for sometime now. I initally noticed it about a month ago, but wasnt to concerned as i dont drive it at full throttle very often anyhow. When accelorating WOT from 0 to what ever speed or even when in second gear and it down shifts to first then to redline. Its not the 2-1 downshift i have a problem with its when the throttle is wide open and the 1-2 shift. Its like the trans cant shift at that sort of RPM so the trans stalls then its a jerky shift into second almost as if something may be wrong with the torque converter?...car has 77000 kilometers on it. Im going to do a trans service when I get to work tomorrow as well as reset actual values in the trans, but any suggestions in the mean time?
