I like to think that making mistakes is how we learn. Don't let this get you down too much; it might not be even that big of a deal or that expensive to fix for Walter. At least count yourself lucky you have a good mechanic to take your Benz to...There is no shop around here that will take mine (including the Mercedes dealer!), so if I mess up I'm on my own...
To put things in perspective: I once attempted what should have been a minor repair to my cars ignition lock (years ago, and it wasn't a Benz) and I ended up setting my beloved car on fire due to an electrical short that I created.
So, just sayin': Only a little transmission hiccup? Could've been worse.
