I drive a 2003 Mitsubishi Diamante, 6G74.
It is fairly smooth, with the exception of high load, low rpm driving.
So, 5th gear under 2,000rpm on an uphill and there is a humming type harshness.
Is there any way to get it smoother in that rpm range?
The TCU is hesitant to downshift to 4th when the torque converter locks up, and that is the scenario that it is most harsh at.
