Hope this is in the right place. I got a great deal on a low miles e320 it’s a 2004 79,000 original miles . The guy I got it from did the classic conductor plate and it ran fine for 4 months then it ended up in limp mode he parked had enough posted it for sale . Here is where I come along I was barely able to move it for the tow truck to bring it to my place it was slipping bad. Got a good scanner and got these codes :p2500 p2561 p220a p2562 p2560 p0715 I cleared the codes jacked up the car and inspected the bottom found the transmission electrical connector leaking it looked relatively new I assume replaced with the kit he installed . My assumption is with the bottom covers on and the slow leak he never knew what was going on and after 4 months enough fluid came out to put him in limp mode . After I discovered the leak I drained the fluid from the transmission and there was enough fluid to fill a Gatorade bottle 28oz. Fluid was not looking good considering it’s only 4 months old . Now what I did was replace the electrical connector , new pan gasket and filled the transmission I did purchase the special dip stick but I was not on even ground so I put about half gallon of fluid in it started the car and let it warm up and it wasn’t slipping as much I don’t have a lot of experience driving this car so not sure what normal is I drove it around my parking lot a couple times and all seemed ok when I was pulling into park it started slipping and then I got p2561 and p2220 I didn’t write them down but I’m pretty sure that’s what they were and now I’m asking you experts did this 79,000 mile transmission get smoked from lack of fluid I also should mention I did change the filter too

 

well you might get lucky P2220 is starter lockout contact Y3/6s1 and or Y3/6i transmission oil temp sensor is faulty------that means a new conductor plate

The 2561 is dicey as 2 gear is implausible or slipping now that could be the disc or the conductor plate solenoid----the solenoid is easy, the disc on the other hand means a rebuild or you donate the car to the red crescent
Hope you like a crap shoot

 

I've had decent luck with Lubegard Red/Platinum additives in old worn/poorly serviced transmissions. Might be worth a shot... was the conductor plate repaired or replaced?

 

The transmission only has 79000 miles on it I might be wrong about the second code I’m going to go check it right now the conductor plate was just done not by me I don’t know if he did it correctly the thing that bothered me most was the lack of fluid when I drained it .once it entered limp mode he immediately stopped driving it

about how much fluid should be added if only draining the pan and replacing the filter?

 

Sorry about the mix up the codes are p2561 and p220a
