I have a question for you tech guys. I have a 1988 300CE and it has a transmission problem I think. It happens when my car gets to its normal temp. When it idles it has a shake and my oil meter, and economy meter move back and forth along with my rpm gauge. Then when shifting it drops lower the 500 rmps and shakes really bad. Some help would be appreciated. Should I take to a dealership or try to fix it myself.
Thanks alot you guys.
