You have a problem that you describe more of being mechanical rather than the elctrohydraulic control unit and a electrical unit,you will have a better resolve with the dealer

I am the guy who pulled the transmission out of a 2005 Sprinter after reading many threads of how to clean elctrohydraulic control unit and replace trans fluid, if still have problem change elctrohydraulic control unit, so it wasn't left at the dealer
Which I did, when it still limp mode. Pulled, disabled and cleaned every part of trans. Pulling pan only changes 4 Qts of fluid.
---Hint----, do not want to take unit to dealer own 3 sprinters have never vested the dealer and came away under 1000.00.
? 1- Must I take to dealer to un lock. Please Add if and when I find the real problem will unit clear limp mode.
? 2 - is there something else to check?

Answer 1

With your voltmeter I need you to measure at the TCM what the voltage output is,

No seepage transmission in wires

Looked at transmission connector at transmission, all pins in there are not pushed in

 engine junction fuse box, fuse #1 which is a 10 amp power to and from fuse, transmission relay clicks, when key is turned on

We are not getting power (12v) to the transmission from TCM at the connector to the transmission with key is turned on (relay closed).

We took the TCM relay apart, measure the (pass through voltage (12v), at the TCM relay with key off, once the key is on (12v) goes away, the relay coil voltage still 12v (relay closed).

Thank you for your help
