im new to the MB world! i have just purchased a 82 300sd with 223k or so miles. im not sure if she is supposed to shift the way she does. from 1-2 she "kicks" into gear and she shifts mostly smooth after that but lateley she has been revving up a little higher than normal to shift. she also smokes a bit. the color of the smoke seems to be a bit blue. the oil hasnt really dropped im the 350 miles i have driven her. any suggestions?? im going to change the tranny fluid tomorrow hopefully that help thank all of you for replying Sarah
