Yeah, the it's good now. When I got the car it had original fluid, 120k miles. Had the seals done back then, and fluid was changed. Just a couple months ago I changed the fluid and filter, about 150k miles. It did have a small pile of black dust under the pickup, I suppose the clutches are starting ot wear out.
Checked it the other day, the level is fine and the new fluid is clean and not burnt.
This non-downshift has been happening as long as I can remember. Unless I come to a complete stop, it will not drop out of 3rd until I really floor it and force a downshift.
