It depends on the particular problem you are having. With mine, I could fix the problem temporarily by changing the fluid. This indicates that the valve is just a little sticky from the clutch residue in the transmission.
The Pressure Control Solenoid controls the engagement of the clutches by regulating the fluid pressure. The accumulator does this too. However the Pressure Control Solenoid can be controlled by the ECM, whereas the accumulator is purely mechanical. Therefore the ECM can use the Pressure Control Solenoid to "trim" the clutch engagement to regulate shifting.
When the Pressure Control Solenoid gets sticky (from normal clutch wear and residue in the fluid), the ECM apparently sees an error in the amount the clutches slip (this can lead to premature clutch failure) so it goes into a protection mode and has the clutch engage abruptly.
Installing a shift kit will change the accumulator so that the Pressure Control Solenoid is no longer "trimming" the clutch engagement because the accumulator has the shift be over with before it will (this my not be a technically accurate description, but you can get the idea).
How hard is the shift kit to install?
It'* EASY!!! If you were going to drop the pan and change the filter anyway, you are already more than half way done!
