I wouldn't do that. Auto trannies rely on pressure. Disconnecting a
cooler line will definitely do funky things to her internals with the
sudden drop in pressure. Why not d/c the lower line on the cooler to
get what you can out of that? The bulk of the fluid you replace with
the flush/change will be synthetic. The remainder of dino-fluid will
be small.

Thanks for the response, info and advice. Let me see if I understand
correctly? You are suggesting that I open the cooler lines and let
what will freeflow out from there? I assume that I should also drop
the pan and drain it as well. That pretty much leaves only the fluid
in the torque converter. Would the amount of new fluid I am able to
fill be adequate to consider this a reasonably decent flush of the
fluid? I am attempting to accomplish the best fluid exchange I can
without having to resort to relying on a dealer. I am open to any
advice and/or suggestion on getting a decent trans flush. Thanks again
for your help and info.

A wise dealer (like the one I use) only drops the pan and changes the fluid.
Many people I know (my father included) has had tranny problems after one of
the flush procedures. The reason is the flush equipment uses the cooler
lines and applies higher pressure than is normally present, which blows out
seals and starts leaks.

Thanks for the response and good info. I to have heard horror stories
about problems from back flushing and have decided to also only just
drop the pan and replace the filter. I am considering disconnecting
the cooler lines to allow any fluid that might free flow to escape.
Also using compressed air to force out any remaining fluid in the
cooler only. I'm sure it will probably be minimal but I want to
eliminate as much as I possibly can safely. I realize this will not
purge all the old fluid but my feeling is that replacing as much as I
remove will at least better my odds of extending the life of the
transmission more then simply doing nothing. If anyone has an
alternate way of removing more or all fluid I and others in this group
would sure be interested in hearing how you were able to accomplish
it. Thanks to all for your info and responses.
