Just posted this in another thread and noticed this one. This service was 5-6 years ago, so I can't say much about nowadays.

I picked up a 300SD this January and it had some receipts in the glove compartment from a place called Marino's in Durham. I had been by the place, they specialize in older MB's. However, this car had some tranny issues - slipped severely going into drive, bad 3-4 shift. The PO stated it was the same problem he had before and he took it there. So me being the internet fiend that I am, looked up some info and came to the conclusion of B2 piston. I took a look at the receipts and noticed that it had already been replaced about 6 years ago, along with the torque converter and a fluid/filter change. I opened up the B2 and transmission pan to find that they hadn't replaced the metal B2 bushing, which is the cause of B2 failure (tons of talk about this on forum). Alas, the B2 was broken with grooves in where the bushing contacts the piston itself. So they replaced the part that was broken previously, but did not replace the part that caused it to break initially--maybe they were thinking more money down the road? Not sure why they wouldn't change out the bushing, but it definitely left a bad taste in my mouth about them.

I must say the times I've called them, they have been very helpful and informative, which leads me to suspect it was an isolated incident. Plus for a new Torque converter, B2, and filter + labor it was only 700 bucks. I'd be willing to give them another chance and see what happens.

They're on Route 17 in Durham. Just my experience, take it however you want.
