I have drained the TCM & PCM by disconnecting the battery and connecting the to cables together and seen a remarkable difference in transmission shifting. No more harsh downshifts from 2nd to 1st and even smoother up shifts so I am here to say that this really worked for me.

After doing the reset, I seen on the DIC where the compass reading usually is displayed, “CAL” and it took a good 15 to 20 seconds until the rpm’s settled to about 560. Then I placed the shifter in each gear for several seconds and then back up to park. I drove less than a ¼ mile and the compass reading returned.

Well I didn't find any particles in the filter when I opened it up so I am hoping this solves my issue.

It did make a change in my shifting.
