I can find no vacuum modulator adjustment on my 300D transmission, and am beginning to think that this must have a mechanical adjustment somewhere.
I am trying to adjust so that my transmission will shift into fourth gear. Now it won't.
Also, I cannot get the kick-down solenoid out of it's receptacle. I have sprayed electrical anti-corrosive solvent onto the unit, in hopes of freeing it.
Any ideas would be appreciated.
