Hi
If I get a used ism does it have to be from the same car? I was told that you could use a newer ism on older one. It is from a 2011 w212 e class and using it on a 2007 w164.

what is ISM?

@Arnis Please identify your car (more than just the model code) and location.

ISM : Intelligent Shifter Module
Its the PRND actuator attached on the tranny outside.

It takes its orders over CAN-C shared by all the main VIP's: F-SAM/ECU/TCU/ESP/LPFP/

> AMAZIN BASIC PERFORMANCE:
ISM is built with solderless pins that hinder performance of neighboring VIP's: ECU/TCU.

I evidenced the whole CAN-C performance is reduced to basic by a few marginal units.

Fixing this ISM + ESP modules is positively where I got my smooth tranny from and likely also GDI timings.

Disrupting ECU/TCU timings with unsustained traffic creates opportunities: clunky tranny + reduced power.
It's easily repaired.

> HERE:
ISM is involved with security validation so this module needs to be pristinely integrated.
I really don't think one can go very far with a mismatched module...

I always say TESTING RULES so let's find out:
crank or no crank???

++++ SEEING IS BELIEVING...

ISM electronically controlled shifter


Quick soldering enables luxury performance
​​​​
Fix ISM+ESP for ECU/TCU transformation. Nice and easy.

Industry standard does not favor repairing modules but it's the only option here!
New modules in US market place are only solderless grade.

ESP is simple to deal with.
ISM tricky to unbolt then easy to fix

I swear this is what @CaliBenzDriver and @S-Prihadi dining rooms must look like!
