I posted roughly 1 week ago on how do i set up the kickdown cable on a 96 E320 W210 5 speed auto model and am still desperate for an answer, i have adjusted it and introduced some more slack and the car drives a lot nicer, but as gearboxes are expensive i would like to make sure i have got it spot on.
Any and i mean any help appreciated.

Thank you
Lynall

Much of it is 'feel' as the cable tells the gearbox how much power is being asked of the engine. By slacking the cable, the box 'thinks' you are applying less power at a given pedal depression, which will likely produce a softer upshift at a lower speed. Cable adjustment, thus, is to some degree a matter of preference and feel.

We will hope others chime in.

Best Regards,
Jim

You're not a miserable git - but I don't have a clue about the transmission. I hope this helps.

I hope some day someone with great knowledge or wisdom or even someone with access to a lot of information will post some DIY and other transmission information. Everyday people seem to have questions about transmissions from fluid type to adjustments and symptoms and it's hard to get the answer we are looking for. A guide for 1975-2005 would be great. I believe there weren't too many transmissions during this time- 722.3, 722.4, 722.5, 722.6.

The Bowden cable, control pressure cable controls shift timing, early or late shifts in the 722. 3, 722.4, 722.5 transmissions as well as part throttle kick down shifts, WOT kick down shifts is controlled by the kick down solenoid which is activated by the switch under the gas pedal.

Disconnect the Bowden cable from the throttle linkage then Adjust the throttle cable/ gas pedal cable first, make sure you have wide open throttle when you depress the gas pedal to the floor, next Adjust the control pressure cable so the ball can be installed without any tension or looseness in the cable; fine tune the cable to your shift liking on a road test or by the book.

Full Throttle Kick down


1-2 2 -3 3-4 1-2 2-3 3-4

E 24km 55km 100km 58km 101km 157km

S 39km 92km 149km 58km 101km 157km

Here is how I did it with my car after some major work on it was done.

I warmed it up, and when everything was cool, I accelerated at about 50% throttle, and I asked myself, "what would be the best rpm range for my car to shift", once I figured what the range was, I tried adjusting the cable 1 turn at a time in the respective direction. When I found the perfect spot for 2-3 shift which is most frequently used in city driving, I then took it on a longer drive down the highway. I floored it to see how it reacts and amazingly, everything was fine, as soon as it reached the red line, it shifted, not before and not after. That's how I left it ever since, I'm considering making some fine tuning to it some time soon, but that's the procedure

To adjust your control pressure cable, you need to look at the black plastic
arm that the trans control cable connects to. On the upper end, it is shaped like an arrow. There will be a matching arrow pointing at it from another part of the throttle linkage. You turn the adjuster nut on the cable making it longer or shorter until the 2 black pointers point at each other exactly. Thats it, unless you dinked around with your throttle cable.
Then, you will have to adjust the whole system to get it in synch.
Have fun.

Thanks for all the replies much appreciated, i had tried adjusting by trial and error but was not happy and Dr Diesel has given me the answer i was looking for thanks for that .
Geuss what i am doing tomorrow morning!

The Bowden cable is made from strands of steel, which Stretch over time.

To maintain and insure the accuracy of the factory adjusting method with the pointer and knurl nut style Bowden cable, you need to use a new cable.
