Hi guys! would like to ask for any inputs on why our Komatsu D155 won't move (forward&reverse), ripper, blade and engine are all normal. and there's a flashing light on the dash with the Gear& lightning logo flashing red. thankyou for your inputs on this matter
Probably too new for me. I'd need a good service manual on it. Have you checked the fluid levels? There would still need to be a transmission pump, pressures to check? Could be a messed up pump or ? Could be some electrical issue, I'm in the dark.
As said above. Overfill the transmission with 5 gallons of oil,start it up on low idle and leave it for half hour without trying to engage the transmission
