Your opinions requested, please gentlemen :
Please correct me if I am wrong, but I have always thought that as a general rule, transmissioin oil is changed at 20,000 Km intervals.
Is there any point in changing it at shorter intervals ? It often looks ratherr dirty then.
For instance, if you were to own a car which has no transmission sump plug, would you take the sump and have one welded in (easy enough to do, as I have an old 505 auto trans sump), so that every 20,000 Ks you would change oil and filter, but half-way through that you could renew the oil, without doing the filter ?
That would certainly be easy, without having to take off the sump.
Or am I getting too obsessive ?
I know that certain makes of car have "sealed for life" transmissions, but I have always thought that to be a dumb idea, as I have heard that their life is not really that long.
