The 41TE (renamed A604) is an all chrysler 4 speed electronic transmission used since the shadow and still used in some modern minivans... and is one of the most unreliable transmissions EVAR concieved.
Not even close to anything Mercedes.

And the "impossible to crack" stratus PCM is a joint effort between Mitsubishi and Chrysler. Same generation software as the neon. One step beyond the PCMs that came in the earlier Spirit and Shadow. All Chrysler PCMs since the 80s up until the DCX units have be probabilistic algorithm based and operate on dynamic calculations with no 2D look up tables to "tune". That's why there are very few aftermarket tuning solutions for any of them.
