ZF tranny 90SP36

[williamcharrison]

The transmission fluid in my sp measures the same level hot or cold.
It also occurred to me that the filter may need changed (I have
owned the coach for 1 year) and it had an engine oil change just before
I took delivery. There are 3 filters located close together under the
engine, can someone tell me what the function of each one is and
possibly a replacement part number?
