Well, my transmission shifting issues are fixed. I finally gave up and took the 1982 300sd to the dealer. They warranty their repairs for a full year - parts too. A week ago the mechanic replaced the two valves on the valve cover. Friday after degreasing the engine, the car started revving up before each shift. Dealer confirmed that the vac valve the independent mechanic put on was defective and leaking. Several people here have said these have no effect except on the EGR. The dealer says otherwise. If valve on valve cover leaks, it sends incorrect pressure to the modulator and modulator will never adjust correctly until valve is replaced. My cleaning the engine had nothing to do with the part failure.
