My Transmission
This never happened to me with this car (2004 CLK320). Should I reset the adaptive driving?

I will monitor in the next few days and report back. Resetting the adaptive driving will not help then.

Resetting adaptive driving will do nothing for this condition.
I drove about 50 miles city driving today and all OK. I will see in the next few days. Thanks.
I did the 2 pan flushes 20k miles ago, I am wondering should I do another pan flush.

I went to an indie for an oil change yesterday. Checked the 13-pin adapter, all dry. Checked ATF level with the dipstick, it's OK as well.
As usual after an oil change, the car was super smooth and I pushed the car hard. This monring I went into dyno mode to check the oil level. The oil level was 8.1L and decreaed as the oil circulated into the engine. There is no warning message of too much oil. Hope this is still OK.
I may breakdown one day to do a ATF pan flush. It has only been 20k miles. I am concerned about using Shell 134 because already 2 kinds of MBATF in my traslmsmom

So, it happened now twice in 8 days. I will go to my indie next week to scan for the code.
My question is if I leave it for a while, would it damage any other parts? Would it get worse, more frequent?
I can see from Autohausaz that a conductor plate is $152US. How many hours will the labor be?

If the problem is with the conductor plate, how many liter of ATF would I need? Anything else do I need?
For engine and transmission parts, I would buy MB parts.

Now I am not sure my indie can handle the job. He works mostly with Sprinter and I'm not sure if he has a genuine SDS. I went to him for the pan flush because the Sprinters share the same 722.6 with my car.
2 hours labour would wipe out the saving going to an indie (dealership labor rate is $140 CAN per hour). I will check if my indie has a SDS. If not, I would perform the change in the dealership. I read that in the minimum, the TCM has to be reset and this needs a SDS.
Is there any software stored in the conductor plate? If so, I will have to make sure it has the latest version.
To save on cost, I may go with Shell ATF134 this time. Hope this ATF will work well with the 236.10 and 236.14 fluids currently in my transmission.
Questions:
1. I am going to the indie to scan the code. Should I ask hiim to clear the code as well?
2. I read that these tranny error codes have to be cleared for the car to drive normal. Since my car went into limp mode, it must have thrown a code. However,my car drives fine and I did not clear the code.

This does not apply to the 5 speed. On the 5 speed you just change the conductor plate.
Have you had any more limp problems with your transmission? If not I would not change the conductor plate. Only do so if limp episodes recur.
P2203 The internal electrical of component Y3/6n3 (speed sensor 3) has filed.
P220A The speed comparison Y3/6n2 to Y3/6n3 is implausible.
Does it mean that I have to replace the conductor plate? The indie who is a Sprinter guy said that for a Sprinter (722.6), there is no need for reprogramming.
I called MB and of course they said this procedure would need reprogramming.
Not sure if this is psychological, after the guy cleared the codes, the car drove better. Is this possible?

Cancelling the codes will not affect driveability.
Benz always says that these procedures require readaption with Star but in reality this is seldom the case especially with the 722.6.
If adaptation is required and I don't do it, what would be the negative impacts? Will the TCU eventually "learn" of the new conductor plate?

I can see that this connector plate is connected directly to the 13-pin pilot bushing. Even if this pilot bushing is not leaking, will a defective unit throw the same codes?
On top of the conductor plate, I will need the followings: 4 liter ATF, filter, pan gasket, 13-pin adapter, right?

Those are the parts you will need plus the conductor plate unless they find a broken solenoid spring etc. once the box is open.
I went to the dealership today and talked to a SA. He said that they would have to do a proper diagnosis before proceding. He said to change the conductor plate, I will have to replace the valve body as well. Something to do with the old valve body would not code with the new conductor plate. This will get expensive.
