Hi,
I am currently having issues with a AC 12G (I think) dozer. S/N 12 G-394. Machine starts and runs, all hydraulic functions work (blade and ripper) yet has issues driving. Machine hardly moves when in gear and any load put on by the blade or slight incline the machine will stop moving. Drive shaft from rear of engine to transmission turns in neutral and then stops when machine stops. Transmission oil is full.s Machine has a power shift transmission with 2 foot brakes and one pedal on the left with a “M” on it. Any thoughts on what the issue could be?

Welcome to the site, but I think you'll get more response, by posting this, over in the construction equipment section.  Think it will have something to do with a pump, in the transmission, but I'm no expert...Wink
