I think the issue with using a machine is the filter is not replaced. But really the filters last a wicked long time and its not like engine oil that can get contaminated. I would have no issue using a machine with the only caveat being that I would want the filter changed at no more than 200,000 miles. I think that is plenty for any modern trans filter.
i think that ok cause the LR factory say to never change oil then the filter is fotever also 😃 and have no a lot dirt if have no broke
