hi, I have a problem with my 621D 2007. When i operate the bucket and hold the brake pedal, the transmission dont disengage. Try to raise the rpm and it still want to move. Temperature raise like hell in the front and rear brakes. Look around in the parts catalog, dont find anything about the Brake clutch system. Case use a different name for that ? any picture, advice info, data, whatever to help me ? Thank you !
Always have to put it in Neutral, to move the boom/bucket with higher rpm. If i stay in Forward or reverse, it want to move.
