it is a cat 428B with the extended boom at the back i think it is a 2004 model
Mechanic: Dan, Technician replied 2 years ago

Hi Sedick, I believed the B model dates back in the 90s Is your shift linkage for forward and reverse all mechanical or is it an electrical shift controller? Check the transmission filter and oil for signs of metal/debris and discoloration of oil an burnt smell indicating an internal failure. Let me know.

you right it is 1994 model and it is mechanical shift we have loose a pipe at the torch converter and found metal in the oil.
Mechanic: Dan, Technician replied 2 years ago

Thanks for the info. If it is aluminum it is converter failure. check the filter and suction strainer to see if there is any friction material/clutches, steel, or all aluminum. Let me know as it will help determine whether you might be able to get by with a full flush, charge pump, oil cooler and converter
