Hi, i'm new here and my english is as bad as my dozer technical condition right now.
Dozer D6N LGP, serial DJY00951.
So, all starded when i felt strange gear shifting- short break between, for example, 3 to 4 gear while moving in reverse. And i notice quiet noise from transmission hydraulic pump- buzzing sound at full engine rpm.
Then i turned down engine and started again and noise was gone and gears shifted smooth for 10 mins.
Now dozer is not moving in first gear properly- when i switch forward, it moves a bit and stops immediately and then moves again. After a while of not moving in first gear it shows Serv Code 673.02 or sometimes 671.02.
Other gears shift +/- normally.
As i know those Serv Codes means problem with speed sensors. Is it possible that all this trouble is because sensor or wiring failure?
What should i do next?
Thanks in advance!
