Larry; My transmission guy always chastises me for using rubber hoses.
Technically, I guess he is correct, metal is less likely to be installed
poorly & fail because of a stupid mistake. I have used rubber lines for
years however without a problem to plumb the coolers and trans together. I
do use Hayden rubber oil lines because they are heavy and designed for trans
fluid. I have had minor leaks around clamps, but that is all. They have
never just blown on me, and I'm talking 750,000 miles in total by now.
There is not that much pressure in these lines anyway. You just need to use
common sense and support them, keep them out of harms way and don't make
real sharp bends in the lines that could kink.
As for the fluid change, in my opinion, its not necessary to get the
entire fluid volume out. The trans is not subject to the combustion
byproducts that cook & contaminate the fluid as it does to engine oil. I
would rather do 3 partial trans oil changes that remove 1/3 of the fluid
each time than do 1 total draining. Just as an example, if you followed this
regime for 10 oil changes, after 30,000 miles (assuming 3,000 mile change
intervals) you would have 98% of the original fluid out. It may actually be
better for the trans too. walter bright. Delanco, NJ wtb58
