Absolute cleanliness is essential when working on the transmission. Before opening the hydraulic circuit, thoroughly clean the area surrounding the separation point. Only lint-free cleaning cloths may be used. Even the smallest dirt particles in the hydraulic components can lead to malfunctions and a total failure of the transmission.
For repairs always wear oil-resistant, fiber-free gloves which are lined with rubber.
The transmission components should be stored in clean surroundings. Here we recommend covering the components or storing them in a clean plastic box with a cover.

If the transmission oil is burnt or contains abrasive particles, the oil cooler must be flushed out or replaced to prevent malfunctions or transmission damage. If too much automatic transmission fluid is added it must then be drained off, otherwise the automatic transmission may be damaged.
An increase in the transmission oil level may be the result of unwanted addition of coolant. This could be for the following reasons:
- Leakage on oil cooler,
- O-rings between oil cooler and transmission housing brittle or leaky.

The hot measuring range on an automatic transmission at operating temperature (70 to 90°C) is decisive for determining the correct oil level which, in turn, guarantees trouble-free operation of the automatic transmission.
Only on transmission 700.750
The hot measuring range on an automatic transmission at operating temperature (35 to 45°C) is decisive for determining the correct oil level which, in turn, guarantees trouble-free operation of the automatic transmission.
After replacing the oil cooler, the transmission oil temperature must be ≥ 80°C to determine the correct oil level.
Only on transmission 725.0 in model 907
The hot measuring range on an automatic transmission at operating temperature (50°C) is decisive for determining the correct oil level which, in turn, guarantees trouble-free operation of the automatic transmission.
Only on transmission 725.0 in model 447, 448
The hot measuring range on an automatic transmission at an operating temperature (40°C) is decisive for determining the correct oil level which, in turn, guarantees trouble-free operation of the automatic transmission.
