Is adjustment procedure the same for oem modulators with port on the side as pictured? Screw in for later harder shifts? I can’t find anything in my service manual. Thanks in advance.
The OEM modulator was not meant to be adjusted. If you notice, it has sealer where the threaded screw enters the modulator. If you want try adjusting it, I would seal it each time using RTV silicone (that's what it looks like to me). If you don't seal it, it will leak vacuum past the threads. I would think it adjusts the same as the aftermarket brass modulators, but I could be wrong.
