Backhoe Looking for tansmission oil type for older JCB 1700 series backhoe.

[bondkrug]

Can someone Pls help me with what type of transmission fluid my backhoe uses.? I don't have an owners manual and the system is a bit low. I have an older model JCB backhoe loader, 1982 1700B model. Im not sure but I heard the original transmission oil type is no longer available, I think its TQF. is there an equivalent. I appreciate it, Thanks. JIM
