Strange shifting when cold - help please
Hello again friends,
My 1984 500 SEL shifts a bit strange when cold. The transmission delays the shifts when cold and often flares as if there is not enough pressure applied to the clutch package. This happens only on medium acceleration and not on light or full throttle. Once the transmission is warmed up it works fine (except that it downshifts a bit to quickly when I touch the gas pedal). Some weeks ago I adjusted the pressure modulater a couple of notches clockwise which cured shift flaring when the transmission was warm. Is there some sort of device that alters the shift pattern when the car is cold or is this just a matter of tuning the pressure and the bowden cable? Thanks for Your help, Mikael Westerberg 1984 500 SEL Vanersborg, Sweden |

Hi,
If your car is with cat it is perfectly normal with delayed upshift before the cat is warmed up. (Have you yet discovered the new Swedish site mbsca.com? They also have a forum, maybe more familiar with your car which is not always the same spec as in the US.) L. |

Thanks for the help,
I got no cats on my car so I have the 231 Hp engine. I will check out the site You mentioned (sounds interesting). The shift pattern is definately different when the car is cold and as far as I know the transmission is not electronically controlled why I my real questions is how the shift pattern change is controlled. Is there some sort of a temperature switch or? Secondly I know I saw a post to a link (quite some time) ago that described how to adjust the bowden cable and the pressure modulator but I cant find the link although i searced the archives quite a bit. So if someone know the link please let me know. Thanks again, Mikael |
