I have a 1994 C180 with the 722.4 gearbox. I want other owners opinions on when it should shift with your foot flat down.
I have just recently done a fluid and filter change. I drained the torque converter too. But this didn't change the wide open shift points.
The car shifts early in my opinion. It seems to shift through all gears at around 3500 - 3750 rpm if you are at full throttle.
If I shift it manually starting in 2 it will rev out as I would expect. If I then manually shift to 3 again it will rev out no problem only changing when I then manually select D
It can also reluctant to kickdown. It will kick down at low engine speed but not if it is going to bring the engine speed above the 3500 - 3750 range it seems to like. Again if manually downshifting from d to 3 it works and gives me the power for say an overtake.
Once into 4th it will rev past the the 3500 range.
The transmission shifts smoothly. Changes into reverse without a clunk or fuss. Changing the switch from E to S does make it hold gears a little longer before changing up on low/part throttle but it will still change at the same RPM range when at full throttle.
