Instuction manual says to change the transmission filter after the
first 10 hours of use, but that you can replace the fluid that was
drained out as long as it was kept free from contaminants.
1) Why is it necessary to replace this filter after the first 10
2) Doesn't it seem self-defeating to put the "used" oil back in the
transmission case? Thanks.

Any machining operation leaves metal bits hiding from the most

that the filter will collect (hopefully) all the nasties that normal

insurance. Since the oil has already been filtered, there is no reason
to think it is contaminated. So why not reuse it? Seems sensible to
General idea I agree...
I'd say sounds more like the manufacturer has decided to shave their
costs by passing on the final cleaning operation to the consumer,
however. Other manufacturers don't seem to have the problem to that degree.
More crud will be generated / loosened and hence filtered during the
No, since the filter has filtered it, however it seems more hassle to
make sure the drain pan and surrounding area is clean when draining,
then wrestle with trying to funnel the oil back in, than to open a few
dollars worth of new oil to pour in.
The break in period has the highest wear of a machine's life. Therefore
"IF" there are any contaminates in the filter this is the most likely
time to replace it for continued good flow. Another thing is you do not
want restricted fluid flow early in it's life. It will shorten the life.
The filter cleans the oil therefore the oil is clean.
