quick search of P2100 shows the following - "1-2 And 4-5 Shift Solenoid Valve Malfunction".
Please search this forum with 'pilot bushing' or 'trans connector'.
Check the trans connector and the pilot bushing. When you open the pilot bushing, see if the oil is on the pins/connector. If you see oil on the pins/connector, change the pilot bushing.
If cleaning/replacing the pilot bushing doesn't solve the issue, you may have to change the 'conductor plate' that holds the solenoids.

If you're getting the error code because that 'plug' is leaking then you need to look at the TCU (under a plate in the front passenger foot well ) for trans fluid migration/contamination up the wire loom. Use circuit board cleaner and compressed air to clean/dry things off and hopefully you'll save the TCU.

Go well - it's a pretty easy DIY. I find as long as I carry spares I have no trouble. LOL
At $8 each it's good insurance.

You have a Cat converter on the way out
OR
You have an upstream O2 sensor that is cycling too slowly & effecting fuel trim to the rich end of the scale.
How many miles on the car?
What is the general state of tune?

Glyn,
i spoke to my mechanic and he did verify that he did not dry inside where the bushing was leaking. He didnt want to spray brake cleaner in there to dry it. Is it ok to do that.And do you think that s the problem that it is still wet.You have been so helpful that is why i like this forum.

You have to dry off any oil that might get on the connector pins or into the harness. The oil causes a partial short across the pins a sends wierd values to the TCU.
Regarding the other code - 2000 - clear it & see if it comes back. I don't know why you are not getting an O2 sensor code if it's going out. You might have a Cat failing & I think you are protected by US law up to 80,000 miles so you might get Benz to pay the bill.
When your car was tuned - did they mess with the ECU mixture mapping?
