6.0l Crusaders with ZF Hurth Xmissions
Manuals have some conflicting information on changing the transmission oil. Here is what I believe is the process. Please correct me if I am wrong.
1. Start engine and get the oil flowing in the lines to the oil cooler and in the cooler.
2. Stop engine and ASAP check the oil level (without screwing the dipstick back in) before the oil in the cooler and lines can flow back to the xmission. This is done so that when running the level is measured with oil in the lines and the cooler and filled as indicated by the dip stick. If not done this way and the oil has flowed back to the xmission the level will be low when the engine is running and the lines and cooler are filled.
3. I will note that the measuring portion of the dipstick is close in color to the fluid making it difficult to see just where on the dipstick the oil level is.
Appreciate comments on this. Thanks.
