Transmission Shift Modulator - bd1308 - 09-08-2012
Long time listener, first time poster...
I have a 84 300D that I drive somewhat frequently, and ever since I've bought it I've been having an issue where the transmission will shift somewhat harshly into gears. Not really noticing a huge mercedes diesel presence in Louisville,KY leads me to believe finding someone to help me figure out exactly what is going on or confirm my suspicions is going to be a bit challenging. However, using my vacuum pump (sears all-metal mityvac) I isolated the transmission modulator as a source to my problems. It's not pulling any vacuum. I get 22 from the pump, 15 from the VCV on the IP, and 0 from the modulator. I bought a new modulator, but either I need to drop the transmission or I need really really tiny hands to get everything out.
I saw a picture that looked like there was plenty of space between the shift modulator and the rest of the body of the car, but mine has about 1/2 inch of clearance between the modulator clamp bolts and the body of the car.
Any tricks? The only thing I have left is shock/motor/transmission mount replacement, transmission fluid/filter change and rear suspension (maybe). Trying to do what I can to keep this car on the road for a really long time.

Really just removing the trans mount should give you enough wiggle room to get to it. With the mount removed, the trans will drop a full 2” in the rear.
Its important to remember to remove the clips on the fan shroud up front b/c the whole engine will tilt and put pressure on it.
