Hello again, buddies,
I changed the tranny fluid, a bit better but still not what it used to feel like.
It can't be the keep alive thing, my battery died a few months ago and I went through the complete "resetting"...
And no, a supercharger or a tune up shouldn't be needed to get back to the begining...
The uphill roll back is what makes me believe I am not being subjective...any further suggestions?
Have a great day everybody
I've not built any automatics in decades, and I know a lot of things have changed. I suspect there isn't really anything worng but what you are noticing is natural wear not failure.
Instead of guessing, I would go to Ford and ask to speak to their tranny guy (if dealers even have one anymore. When I was a tech. we actaually rebuilt and repaird engines / trannys ourselves as opposed to farming it out or getting a crate replacement). If they don't have a builder on site, try to find a well known transmission builder with a good rep.
I wouldn't be surprised just an adjustment of some sort is in order.
It seems you are looking for that tight/crisp feel of a new product but you're driveing something that has loosened up a bit and it bothers you. It can't stay new forever, but it can be adjusted. Just like drum brakes have to be adjusted once in awhile, sometimes so do bands in a transmission (if it has them, not sure about this tranny).
Torque Converters... Yes, they do go bad and they do become worn. I've never personally repaired a vehicle where the torque converter specifically had this as it's only issue, but that doesn't mean it's not possible. In my personal anecdotal experiences, when a torque converter goes bad, it presents with other problems that are way more noticeable than lack of idle creep or hill holding. However you should speak with someone who makes a living at this, my knowledge is decades old.
Valve Bodies... They do wear, and they can lose pressure when starting to fail. A valve body can be diagnosed by a good transmission guy.
So the bottom line is, don't keep guessing. Find a good professional, tell him the problem, pay for a diagnostic then follow through.
