The oil needs replacement, together with flushing the gearbox, but if that would be a mandatory requirement, then the estimated service cost for the vehicle would look too high.
I've replaced the oil in my TF-80 SC after about 120000 km. Gear change quality improved significantly. The old oil was darkish red, the new bright red.
Do you have a process that you followed to get all the fluid out? Not the drain and refill method of 3 liters at a time, but one that pumps the old fluid out and sucks new in (or new is refilled from the top of the box).
I have a case of 3309 waiting for me, if I can't find any documentation, I'll just try some options to unhook the cooler lines to get one to pump fluid out.
Thanks,
