Hi everyone, I noticed in my 5 speed auto Mitsubishi Diamante that after I reset the ECU the transmission shifts smoothly. The TCU has a "fuzzy logic" way of adapting to drivers. After a while the shifts start becoming harsher, like the slip time between gears is short and there's a bit o a jerk. It does not feel wrong/broken, but I would prefer smoother shifts. What would govern the shift smoothness? The transmission programming, the solenoids etc? The transmission is regularly serviced, the ATF was recently replaced and is at the right level.
