Hey guys,
Im getting frustrated with the tranny problem. First off, Driving the C43 and then losing gears like/feels like im in Netural when its at operating temperature. CEL came on, checked it and got the P0700 code. Replaced with conductor plate, connector/adapter(No trace of fluid) and did flushed the tranny fluid with new fluid and gasket. Reset the code with MBstar computer..Drove fine for the first 30kms roughly, then bam the CEL come back on again. P0700 pops up. Check the TCU for trace of fluid, none found. Electronics sucks..Need your help, ppls. Thanks in advance.

 

I think something wrong with TCU, or TCU plug connectors/harness, did you check any of these..??

ZAYED,,

 

cm60k, thanks for the reply. BTW, do you know where the TCU is located? I checked the passenger engine side but only seen was the fuse block and ESP ABS Bosch Unit.

 

follow electronic connector that runs from transmission. it connects directly to TCU. it's underneath, not far from the transmission.

TCU located inside(under passenger floor mat), when you remove floor mat, will see alloy metal it's attached to it..!
