Kick down switch on a 109 4.5 - PeachParts Mercedes-Benz Forum

I had an excellent kick down switch would really punch at about 60 or so. When I had my transmissions gaskets replaced somehow it got screwed up and now the "kick down" does not occure untill about 45 or so and much of nothing at 60+. I will not take it back to the tech that the the reseal. How do I adjust my Kick down switch?

If you shorten the rod pictured (remove the air filter assembly), it should raise the shift points and the kickdown points.

Tom, what should I expect my shift points to be around? I think its shifting a bit... premature... Although from what I remember from my 67 250SE, that was common with the 3spd autos....

Depends how much throttle you use when you accelerate. I have a heavy foot, I think mine usually shifts around 25-30 and then 45-50. If it shifts early on you, shorten the linkage rod as pictured.

Well thanks Tomguy, thats it, nothing on the other end?

Maybe, I'm looking for a passing gear, I had one before I got the tranny sealed now I do not have much of one at all, from 60 to 80 I used to rocket by cars now Its just a slow pony.

If you floor it at 60-80, it should DEFINETLY kick into 2nd gear. If it doesn't, chances are that switch got disconnected somehow. Check the plug and wires for it.

I'll check it, thanks my friend.

hm, shifts a lot earlier in traffic than I remember. Into 2nd probably around 15-20, and into 3rd probably at 30-35 (maybe earlier).
