Any danger to low trans mod pressure

[sjh]

Greetings,

I have a '90 300D, 2.5L Turbo. It's a nice car. I've had it about 6 months. So far I've done the wastegate swap, pulled the dash and replaced the vacuum actuators, pulled all of the vacuum devices by the turbo for the wastegate, EGR and flapper (is that the ARV?), pulled the blue flying saucer, properly set the VCV and have good system vacuum.

The previous owner had the transmission modulator replaced. I assume when the mechanic installed it he kept on increasing the pressure until there was no flaring. However, with the removal of un-needed devices and properly (hopefully) setting up and maintaining the engine vacuum's system the transmission modulator vacuum appears to be much too high.

I have backed the adjustment valve off about 3/4 of a turn. The abruptness of the shifts has decreased but still does not seem correct. I owned a w123 for 15 years and have driven other w123 and w124 so have some sense of how the tranny should behave in these vehicles.

The mod pressure is still too high. Is there any potential damage that can occur with me decreasing it further?

My understanding of the blue flying saucer is that it is designed to smooth the shifts. I may need to reinstall it. Any comments on the BFS and if (and how) it can be adjusted.

Thanks.
