There are some other ideas too other than the worst case.Įven if I have to spend $20K on two new transmissions, I'll still be okay, because the unit has a good engine and new undercarriage. I have spoken with a couple 850B owners that say I should have the transmissions pressure tested and set, and that this may fix it. Without a load, pressure is about 250 lbs on the gauge. If the temp gauge is working, the transmission doesn't heat beyond normal. There are times when it steers fine under a load and times that it won't even counter rotate correctly. Under a load it does lose transmission pressure and the power to the tracks is almost nil. Yesterday was the first day I could really run it and try to diagnose. I just purchased a Deere 850B dozer rather cheaply at auction because it was stated that at least one of the hydrostats was getting weak.
