According to lexia you have a faulty gearbox, particularly slipping brakes or clutches. This needs a rebuild or replacement box. Cooling the oil won't fix a broken gearbox, the heat is a symptom of the fault and not the cause of it.


The fault won't go away unless you physically repair the gearbox and then replace the oil.

The oil temp should be between 60'C and 80'C. At 119'C the fluid might be breaking down and loosing it's properties and the clutches/brakes might be slipping because of that (I'm not sure, they still might be worn out).
Scale from using tap water can build up in the fine galleries of the transmission heat exchanger. This will cause overheating of the transmission fluid.
