Vacuum kick down module
 

Good morning,

I'm installing a use auto trans into my 95 e320 wagon. The trans that came out has number 1242712401. The used trans I have is number 1262712101.
The only difference I can see is the one that came out has a vacuum module as part of the kick down. The used one I'm installing has only the cable kick down.

Will the "new" used trans work if I plug the vacuum lines and use only the simple cable kick down? or will I need to transfer the vacuum module?

Thanks,

Would you happen to know the 722.x number of those transmissions?

Typically there are a few external connections on 722.3 and 722.4 series transmissions.
1) Vacuum
2) Bowden Cable / Kickdown Cable
3) Kickdown Solenoid
4) Neutral Safety Switch

I'm not sure about the 722.5

It should have a vacuum modulator on the bottom. See the pictures in this listing:
