My perfect Ranger with an imperfect transmission...

[Msfitoy]

That's ridiculous blaming Ford and/or calling names as the answer to the failure is in every article I've read and in the opening paragraph about the 10 speed tranny - a joint development between Ford and GM.

People tow heavy stuff with this tranny, people that design things understand there will be occasional early failures, I think it's built Ford tough.

I don't know who/what to blame but it sure ain't heavy use...lot's of miles sure (if 90K is a lot these days) but in my case it's been treated with TLC from day one...again, no tune, driven like a tour bus on flat terrain, tows a mower to service once a year...

Since ask it is related to all Automatic Transmissions. I wont argue that the 10R80 is designed to operate in a certain Temperature Range. That said when transmission temps are getring close to 250° F wich is the point the ULV transmission fluid starts to deteriorate you can start to have problens. During the time I had my Ranger(yep still miss it) I would see the transmission temps get that high when OffRoad at slow speeds in heavy obstacles and when towing up some very steep grades. I'm sure that did not help the transmission what so ever. That is why the PPE Pan would make a huge difference.

Totally agree 250 degrees is too hot. Keeping the temps within it designed range is different than keeping it as cool as possible. I agree that some addition cooling, like the high capacity finned pan, is indicated under high load conditions. I do disagree that whatay apply to "all" automatic transmissions applies equally to the 10R80.

I still hold that until we know the actual cause of this failure, if we ever do. All this discussion is just a lot of conjecture and fear building. Was it a wear issue, was it a component failure and for what reason. Or was it heaven forbid a design issue. We may never know. So lets just keep making up reasons why the 10R80 worst transmission ever designed and foisted on the driving public. Seven pages and I'm sure at least thatany more.

Said my piece, I'm out of here.

For transmission temps it is best to try and keep it as low as possible. The only options we have for added cooling is the PPE Pan that adds the fins(and a drain plug) that alone will make a huge difference. Disabling the thermostat function is a bad idea. The computer control should still be in place as it will help the transmission get up to operating temps faster and help control it. As for a more efficient cooler.... Unfortunately that I am aware of i dont think there is one available

Is there a setting in Forscan to control the temp threshold for the Transmission thermostat? That would be very nice feature to have!

I'll check with Xtools support to see if the D8 can be programed to set/control the transmission thermostat. It has a great deal of capability and support is quick to add requested features.

If you live in the southern US, the temps here seldom drop to the levels of cold facing the northern climes.

I also believe that the F150 has a large transmission cooler at ther front of the pan. However It may still be controlled by the module. I have not looked into this area in any detail at all. But I think my PPE deep pan is going on sooner rather than later.

Thks for the thoughts.

I'm confused, are you saying that the joint development or GM is the reason for the failure of Sid's transmission.

I don't know who/what to blame but it sure ain't heavy use...lot's of miles sure (if 90K is a lot these days) but in my case it's been treated with TLC from day one...again, no tune, driven like a tour bus on flat terrain, tows a mower to service once a year...

I would feel the same as you, but lacking a pattern of increasing failures like Chrysler auto boxes inthe 80s and 90s seems difficult to say it's a bad design, but not lacking in complexity and that brings more failure points. Now being an old codger I did bring up 2 speed powerglides from the 60s and those boxes were robust, mostly seal failures but the clutches were heavy duty and it was all mechanical. I've weighed in favorably on EVs here despite their drawbacks they are less complex and more efficient in their use of energy. Back in the day I remember replacing my dad's 70s Chrysler torqueflight in his driveway with just a few jack's and jack stands. Perhaps you may only need a new valve body, good luck.

For the record, my transmission is behaving quite nicely, esp since the driveshaft was added.

I simply want to maximize longevity. I am not in panic mode or trying to fear monger. But I do want to protect my investment.

I'd rather spend money on preventative maintenance and mechanical improvements than on repairs. And I'd rather give my $ to 3rd parties than to Ford. I do not want to encourage possible bad behavior - it being either in the form of planned obsolescence, service and repair, or insurance against such.

Finally, this much I do know - Sid didn't make the Ford Engineering 150K 90% reliability standard, and he babied his Ranger. Several people on this forum have noticed the excessive temps at 200+, and all of us old school shade tree mechanics know what 200+ temps do to automatic transmissions. Maybe the 10R80 is different and it likes high temps. Maybe not.

The first thing that made me have a double take when I opened up the tranny sump to replace the filter was...damn...there's wires and harnesses in this hot liquid...hmmm....

That is more common than you would think. Want to say ever since the electronic transmissions came into play in the 80's it has been happening.

Ok, so i read through all the comments.

Sorry dudes, transmissions dont last as long as they used to. Lucky to get to 150k without issues. Just the nature of the beast. I wish i had the solution as to how to keep this from happening. But this is all makes. And cvts are even worse for problems.
Not saying its right. Just saying transmissions dont make it to 100k anymore. It has been the trend for the past 20 years. As a past mechanic, saw it a lot. With cared for cars and abused cars.

That being said. I am going to fork over the money for the deep aluminum pan.

And whats with the drain plug????!!!!!!??????

I have worked on many, many, many transmissions and diff covers with no drain plugs. Just unbolt , drain, clean, change filter, gasket , or ford gasket maker works the best!!, refill, burnouts repeat.

Edit. On the plus side, modern engines have no problem with 100k or more!!

This is exactly why I bought a 150k warranty. Peace of mind. Just passed 48k after 2 years and problem free, but you never know. My wife and I are debating purchasing a 3rd vehicle as we both work and need both our vehicles. Service delays are a big part. Good luck with your truck!

we did the same thing . 150 k do about 20k a year did the 0 deductible, the way these car are made you need the xtra warranty if the center screen goes out its 3 k ..

I like a controlled drain into a pan, not fluid raining on me! It is also easier to measure - to get in the ball park before validating level and topping off. I LIKE drain plugs!

So lets just keep making up reasons why the 10R80 worst transmission ever designed and foisted on the driving public.

I know of a lot of automatic transmissions that are FAR FAR worse.

I stopped purchasing GM cars in the late 70's, and Chryslers in the early 90's. The Chryslers were esp bad. Had a 1993 Concorde that would go into limp mode intermittently every time it warmed up with 30K miles on it! Took it to the dealer multiple times to no avail. Dealership couldn't or wouldn't fix it. I let it sit overnight at another Chrysler dealership and traded it in for a new one. It drove flawlessly around their parking lot!

Chrysler sold me a lemon - And I sold it back to Chrysler!

And never purchased another.

just curious, at what miles and how many times did you change the trans fluid ?

That we are aware of it might of happenes once. Even then Ford recommends 150K
