Transmission Vacuum Modulator Adjustment
My 87 300D's transmission shifts too firmly, and I've read that the problem is most likely a vacuum issue. I've checked for any loose vacuum lines in the engine compartment but all seemed connected.
A technical service bulletin mentioned a modified vacuum modulator to reduce the vacuum pressure to the transmission which was made available to address the hard shifting problem. How do I get the modified modulator? And where is the modulator located on the tranny?
