Hello, everybody.
In spring, as already described in another topic, I plan to change the oil. make the flushing on the machine.
Motor ABH automatic drive with additional oil cooler.
We'll check it out. Does anyone know which of the common RL to the gearbox is the VL from the coolers?
According to my research and logical understanding, the upper connection to the water cooler is the RL to the transmission to bring the automatic transmission oil quickly to operating temperature and the lower connection from the supplementary oil cooler of the RL to the transmission (since there Temp.Fühler is installed and probably the temperature to the transmission is controlled) because the two connections converge.
A thermostat should not be installed in the gearbox, since the VL goes from the gearbox down into the water cooler. Would mean a quick temperature increase of the oil in the RL to the gear in cold condition is desired. With a temperature drop, I would never go into the water cooler below thermodynamically, or how do you see that? With the oil cooler it makes sense to drive out below and to regulate the temperature there.
