Brand new to Mercedes. This is actually my wife's car that she's wanted most of her life. We found a used one in pretty good condition so we jumped on it. A couple of things I'm working on right now with it:

1. Hydraulic leak in the rear passenger side. Put the top down the other day and when we went to put it up the trunk would open but the top wouldn't come up. Found the thread about rebuilding the actuators so I've ordered parts for that.

2. Car seems to be shifting hard. No check engine light but throws the following codes: P0715, P0156, P0150 so I'm currently looking into those.

I'm far from a mechanic. Basic stuff like oil changes, etc. are up my alley but tearing down a transmission or fishing out a complicated wiring harness (for example) is usually where I start looking for help.

Let me know if there are any Melbourne (or close) members that are experienced with this car and enjoy working on it...I've got plenty of beer in the fridge for payment!

Looks like Merc sold a lot of SLK320s in Florida. Am in SW Orlando but have quite a bit of testing gear.

P0150 O2 Circuit Slow Response (Bank 2, Sensor 1)
P0156 02 Sensor Circuit Malfunction (Bank 2 Sensor 2)
P0715 INPUT SENSOR MISMATCH (is it an automatic ?) Transmission Input/Turbine Speed Sensor Circuit Malfunction

I'd clear all codes and see if anything comes back. Mercedes are like elephants - they never forget.

Hard shifting - may be related to the 715, are you using W - Wife or S -Sport. Keep in mind that these transmissions "learn".
