to all the best & Brightest

I want to know if the transmission in this car has the key in the modulator to turn up pressure so the shifting can be quicker & firmer.

I have done it with a few 300sd of w116 and w 126.
Yesterday I crawled underneath play lizard.
i found the vacuum hose on the passenger side, but the lid/cover is facing the top different from the older ones that face to the right passenger door.
Because of tight cramped space I cant fit my finger or see anything when viewing from underneath & side.
Also the dual exhaust down pipe is in the way greatly, not much room at all. Unless I drop the exhaust pipes, or tilt the trans rearward, either way is a major undertaking.
