0894 code on $150 w164
Im getting 0894, and 0893 codes from the TCM
which caused the P0730 code in the ECM
I replaced and programmed conductor plate, along with fresh fluid.
Level is correct and filled at 45 C as required.
Still getting the same issue except now it wont move when shifted into D or R. Just revs like in neutral and sometimes it’ll slam into gear with enough rpm. Before it would drive fine until 3-4 gear change and then fall on its face.
My next steps are to replace the valve body and all solenoids with new o rings.
Would this hopefully get the truck back on the road or should I look for a good used 722.9?
(Or manual swap from a C class??? lol)
ps. fluid was ok with not much shavings on magnet. A couple solenoids had broken o-rings on the nozzle
- Thanks
