Take to bench, disassemble one section at a time, clean and reassy in like fashion (get gaskets)

Amazing how much little goopy stuff you will find hanging out in nooks and crannies. Most of a Saturday is more than enough time to do a thorough clean and inspect.

But make sure the fluid level is correct first, as per the detailed instructions posted above.

And make sure that the above job is within your capabilities before starting. You will need a kit from CTSC with gaskets and various seals for the valve body. Test the temperature sensor as well, since your problem changes from cold to hot. The valve body is a detailed job, everything has to go back the way it came apart. There are lots of small pieces. It isn't something to rush through. /end warnings.
