seals are old and worn out, combined with normal shrinkage in cold weather, so fluid leaks and is not able to build up pressure, then as the trans fluid warms up and the seals expand they hold the fluid better
rebuild or replace

I assume the fluid is in good condition and at the proper level? Cant' hurt to check the TV cable adjustment either. Line pressure on the low side isn't helpful in the cold. But yeah, at 300K it's most likely in need of a rebuild.

yeah It's got enough fluid, even though I have to add a quart about every two weeks
