My Komatsu D85a-12 transmission cuts out when travelling…

Customer Question
My Komatsu D85a-12 transmission...

My Komatsu D85a-12 transmission cuts out when travelling uphill. It is like it is in neutral. If I turn the dozer around it will back up the hills just fine with no issues. I have checked all of the hoses and fittings and all seem good. Could it be that the transmission pump is failing? Thanks.

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Construction Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Thanks!

Mechanic's Assistant: Anything else you want the construction mechanic to know before I connect you?

I am also having an issue with the steering clutches. When I pull the levers the dozer will hardly turn, when not under load. But if I step on the pedals and pull the lever the dozer turns instantly
