Nissan Repair: Altima transmission kicks hard at shifting, o2 sensors, computer replacement

Question
Hi, mi altima 95 automatic 180K kicks really hard from 1 to 2 i replaced motor mounts, o2 sensors, tune up, check engine is not on, also i added slick 50 transmission additive, but nothing help the hard shifting enough to pull my neck. I have to drive the car really soft from 0 to 20 to avoid the hard kick but is not always possible. any suggestions to help me reduce the horrible hard shifthing with out replacing tranmission thanks!!

Answer
Al,

If you already replaced the motor mounts then I would suggest changing the fluid and filter.  Email me back if this does not work as it will require a servo or servo computer replacement.  But, the change of fluid and filter seem to work most of the time.
