[Lupin..the..3rd]

Wondering if anyone here has a Mercedes STAR diagnostic computer at home? Or the Snap-On equivalent with the Mercedes module?

I just replaced some faulty electronic parts in the automatic transmission on my '97 E300 sedan. It was a PITA, had to pull the whole valve body out, with ATF dripping all over my head, lol. Anyhow, I can clear the OBD2 codes myself, but the transmission apparently has its own computer that cannot be accessed via OBD2.

Planning to take it to the dealer next week, if no one here has the tool. Just trying to avoid paying an hour of dealer labor for 5 mins of computer work...
