It is the Yucca 395 dozer. I had the plate over the clutch's off last year, and the hydralic fittings going into the clutch packs were like some kids 7th grad metal shop project. one actually fell into the case when the cover was removed. I replaced the “O” rings and reassembled, and replaced the “O” rings on the shuttle valve. again reverse is fine, it is foward that can be a problem. it will run fine one day, and if it cools down the next foward can be a problem.
