Can someone tell me the size of the o-ring from the kickdown cable?

It should be a boot seal.

The kick down cable o-ring should be a –011.

-011 = 7.65 mm inside diameter x 11.21 mm outside diameter x 1.78 mm cross section.

I still suggest that you buy one of those seal kits.

There are two variants of kickdown cable! One with a o-ring and another with a boot seal.
I try to get a single ring in some locale stores otherwise i‘ll order your mentioned seal kit. Have to check if the package costs are ok or oversized for the small package...

So far all of those kits I have looked at ship from the US. I wish you could buy a kit in Germany.

Be careful that you don’t over tighten that kickdown cable bolt the plastic is already cracked just like mine was.

Hey guys
First parts arrived and today i tried to get the diptube changed.
I used the mentioned seal instead of the o-ring but i don‘t get it in the th350! It is so dang tight that it doesn‘t fit. I tried it 40min and gave up. Is there a special trick/ way to get it in? Otherwise i will use the o-ring....

If your new dipstick has an o-ring grove the boot seal will not work you have to use a –113 o-ring. The boot only fits on smaller diameter tubes that are smooth with no o-ring grove.

First: Where is the post from bd??? Why is it erased?

And yes: the tube doesn‘t fit to the boot seal. I had a call with the shop and they will send me two different tube which will fit to the seal. I think the seal is much better than the o-ring, right?!

i know on my 4l80e it has the boot it was a pain to get in but once its there its there and you only have to worry about a leak if you cut the boot when you install it

There's no way to pull the dipstick tube out that will be easy to install. Mainly because my trans is pushed back 3" it make the stick more under the floor of the cab so I can't.really just slide it back in. But if there's no provisions for the o ring then the boot should fit, like Ron was saying.

Hey guys
Just want to give a short update...
At last i found some time to check the truck again. I add the new dipstick with o-ring and change the o-ring from kickdowncable and it is dry!!! Thanks a lot! I also add a new oilpan seal and fixed the screws with 13Nm.
I checked the transoil in P and engine was running and everythink is fine. Final step will be to make a ride and check when engine is hot.
