Hi! After searching the forums I could not solve this problem. I drive a 1989 190D and am experiencing high rpms at about 4,500 and 40 mph for 3rd gear and am unsure about 4th gear but I know the rpms are high on that as well. I took the car to the shop and had the transmission fluid and transmission filter changed. While at the shop the mechanic had adjusted what he called the throttle cable and he took me for a spin around the block and the car had seemed to shift at much lower rpms than before. I thought the problem was fixed. He then sprayed wd-40 on the connections and wiggled the mechanisms to coat the connections. After this I left the shop and experienced the high rpms again. I did not have enough time to return to the shop. I am wondering if this sounds familiar to anyone or if someone could guide me in adjusting the throttle cable to fix this problem.
Thank you very much for your time!
