Hi. I am having issues with my 2004 sprinter I purchased recently. Everything worked fine and then one day transmission would not shift past 3rd gear. If I get up to 40-50 mph and shift to neutral and then back to drive it will shift into overdrive and stay in overdrive until I slow up. Also "sport shift" or whatever they call it does not work. Can manually shift to 3rd sometimes and most of he time it doesn't work at all. Any help would be greatly appreciated. Thanks.

Could be caused by any of the following:
low transmission fluid
wet transmission module under driver's seat from oil wicking up from cables
clogged transmission solenoid, dirty AT oil
Limp Home Mode from many causes that only a diagnostic scan of ECU may find

Where in the world are you located? maybe someone on here is nearby that wants to help with a scanner?

It's at the dealer now and they found some wiring issues under the seat. Have not been able to solve the problem. Transmission level is good.

Some dealers may not be aware that owners have experienced oil wicking up from the transmission connector wires to the transmission control module under the seat ,

Thanks a lot. I'll inform them of that and see if that's what is going on. I hope it is.

i change the conductor plate , plug and filter, problem solved, my transmission was acting eratic and then went into limp mode,

The dealer found bad wiring under the battery area and that damaged the tcm. Repaired wires and replaced tcm and shifts great.

If it happens again, the conductor plate is a common fix.
