Is there anyone that's halfway, almost, a little bit, maybe might have potentially kept up with my car?

At any rate, my transmission is going out! AGAIN! Needless to say I am NOT a happy camper. Not worried about money as I have extended warranty to cover. Ford rebuilt this transmission about 12k miles ago. (just over 1 1/2 year). If this is the craftsmanship, reliability and workmanship that Ford is putting out, then I might just be done. Car will be at dealer on Monday or Tuesday. Car may be for sale the following Monday or Tuesday.

Anyway, car shutters. Meaning at a slow acceleration car jumps, stumbles and bumps. 3rd gear is the worse but gears 3-6 are all doing it. 3rd and 6th gear just more pronounced. To test I reloaded tune. Same problem. Loaded stock tune, even worse. Has anyone else had this many problems with Ford transmissions?

Now Im kinda scared to drive car cuz I don't want to get stranded. My truck was vandalized so its outta commission now.

Doesn't exhibit behaviors of low fluid. Seems more like a control issue. When trans was first repaired couple years ago, I complained about hard shifts and shuttering. They could not verify the shuttering. But claim hard shifts and clunking were normal. Which is BS. But I had them to document it in case this happens.

Not sure I want to reset PCM myself as car still has warranty. If I mask a problem it may not return until warranty is up. Rather they deal with it now. Also, Ford made last repair. I will be on them to pay for repair and NOT insurance. At least I will try.
 
In addition, have you noted any fuel smell (leaky injector), pulled any codes from the PCM (misfire)?  A fried PCM could also be to blame.  It surely does sound like a transmission issue though.  Does the problem occur right at shift point, right before/after shift point, etc.?  Maybe that "goop" issue was caused by a blown motor mount, which could cause some jerkiness during shifting.  Just brainstorming ...

Sorry to hear about your truck :(  How long till you get it back in service?
 
My parents car did something like when their catalytic convertor failed and plugged the exhaust.  Is it fine at full throttle?
 
There are always exceptions but the 6F55 Transmission has proven to be very robust and capable.  There have been a few TSBs for sensors and software tweaking but there have been very few outright failures.

This issue may not even be the transmission but glad you have warranty.  Good luck.

No fuel smell. No leaks. Only issue is the constantly running fan from the 93 tune lol. I thought about motor or trans mounts causing jerkiness too. But its too inconsistent for that and the jerks, lol occur on deceleration too.

At hard acceleration car shifts fine. It when accelerating from a cruise speed where things get shaky. My preference is for Ford to swap out entire unit. And NOT bill my insurance as it should be a warranty issue from their repair. Instead of Ford doing the cheap thing again and only replacing 1 gear at a time.

Whoever pays the most it will cost me is insurance deductible of $200 I think.

And none of you guys commented about that tranny pic? Should I worry about you guys? lol

Thank you for your act of self-preservation.  We will all gladly dole out whackings where they are due, can't let Z have all the fun.

So shudder is only gears 3-6 and usually under light acceleration.
When it does it try putting light pressure on the brake pedal and see if it goes away.  If it does go away it could be the torque converter locking up and unlocking which means bad torque converter.

Its more pronounced then. But my sensitivity feels it everywhere now. May be psychological But I will try testing the converter.

Which will become another complaint. Why would Ford not replace/rebuild converter while the trans is out for a rebuild? And, why would they only fix what is 1 gear? In olden times when the trans came out because ANY gear wasn't right, then ALL gears were replaced. And a rebuilt torque converter installed.
 
Another cause of many shudders that can get progressively worse is a failing coil or two.  This does not create hard shifts just shudders...

Feel your pain buddy... The answer to your question is $$... Hope you get a new tranny and maybe a TC out of this!

Test drove car today. Tried your thingamajig test for converter. Made no difference. What I did notice though was engine surging and hunting. I turn on cruise control and engine hunting. Maybe a 500 rpm swing, but no change is vehicle speed, downshift or anything else indicative of engine speed change. So Im a little stumped now.
 
Might be a MAP sensor (or both) going bad.  Try cleaning them first with MAF cleaner.  Check torque converter PIDs to see if it is going in/out of lockup mode when you see the "surge".
