Since I got no replies on this topic, I figured that I probably answered my own question.

Went to my local dealer and bought the modulator, only because it was in stock there.

Lowered the transmission somewhat, and finally got the 2 allen bolts to release their death grip to the tranny, and replaced the modulator. Also, found that this was the cause of the small fluid leak too. 'O' rings were flat and hardened.

Got it all back together, and test-drove it. What a difference!

No more harsh shifts. No more slow engagement. And best of all, no more leak. I cleaned all around the modulator box before I did anything.

Its been running since Friday AM, and it is doing fine.

PS: I got the CD-ROM. MANY questions are now answered. Hopefully now, I can start helping others with a 190E like I have been helped by you guys.
