The old modulator on my 1981 380sl has a small metal pin that fits into the receptacle on the transmission. However, the Mercedes brand modulator I just bought to replace it comes with a separate, long plastic pin with a little wheel and nipple on one end. Can anyone tell me if this is the correct part and, if so, how to install it.?
Thanks very much in advance, and Best Wishes for a Very Happy New Year.
