I’m truly trying to find out what the facts and realities are of the transmission choices versus 10R80 transmission.

How long did your Stock transmission last?

What did you do to keep it functioning?

Did you have it rebuilt with upgraded parts? If so what?

Did you buy a fully built transmission? From who?

Did you swap with a donor car?

Would you do it again?

What would you do differently?

Did you swap a manual in?

If so what?

Sequential?

Do use it as a daily driver also?

All experience and wisdom is appreciated.

I also posted in the mustang6 forum. due to at times I don’t get replies here and this is a more road course oriented forum which I am interested in.

I think @flyhalf is probably one of the most experienced with the transmission. Even though he moved on to smaller and better things (sequential) lol.

May find a lot of what he did in his build thread.

UPDATE
Ourisman Ford in manassas Virginia said my transmission leaked all its 13 QTs of ULV transmission fluid through the rear of my upgraded PPE transmission pan. They always say this. Another Ourisman LIE!

We would all notice 13 quarts of transmission fluid leaking onto our garage floor and driveway!

I think it is leaking out of the breather valve on the very top front of the transmission. Maybe when hot? Have you folks noticed this small leak on yours?

I fill to 4.5 on dipstick.

They also said my transmission was cooked. Another LIE!

I drove my car to another shop that has a lift and put it up the air.

They had not cleaned the bottom of the car like most people would to then check for a leak.
We checked the fluid level and it was what it should be. Ford and others say when hot the dipstick should read at or between 4-5.

AFTER Driving the car from the liars at Ourisman Ford the transmission seems to work like it’s supposed to.

I had it there for the ill functioning driver assist modes.
The car for no reason would loose all power/forward propulsion. No steering input and all wheels turning the same speed.

I had to unplug the Dyno Plug. I have full control now and the car can be drove with all driver assist OFF. But now I always have a bunch of errors and lights on.
They did nothing.

I truly believe that they never even diagnosed or looked at my car while it was at their dealer for a week or two.
I think they just let the car sit there.
Then they called me and said it was done and ready to pick up.
They said they were not going to do anything or cover anything under warranty, due to their lie that my far better PPE transmission pan leaks out the rear. They used this same lie the first time they finally replaced the transmission under warranty.

EVERYTHING they said was a LIE.

They also tried to get me to leave with no documentation!
I have learned this is another of dealers tricks!
The other is that they will not document correctly. What your complaints/problems are with your vehicle.
This way when you try and get something fixed under warranty, they say you never had any problems, there is no documentation of your problems.
ALWAYS GET YOUR DOCUMENTATION AND MAKE SURE THAT IT IS EXACTLY CORRECT.

11,000 miles, a little track use, daily driver, except I do not really drive every day, no issues or problems with my transmission.

~147k miles, 2-3 track days a month since 2020, no issues at all
