2015, F250 6.2L, 16,000km , so recently my transmission has seemingly lost its mind. When I start it up cold and drive it down my street I am greeted with a horrible slam of a 2nd to 3rd gear shift. Then while towing my TT this weekend a couple of times it held 2nd waaaay longer than it ever has before. Anyone had these types of issues with their Torqueshift?

 

I get it on my 2011 F350 6.2l. Just happened this morning, as a matter of fact. When it hapoens, it's when I'm doing a normal acceleration- like pulling out of a parking lot. It will hang in 1st or 2nd and rev real high, and then slam into 3rd.

It apparently is normal. I looked into it on forums like this when it first happened. Evidently it doesn't hurt anything. Scary to hear when it happens though.

 

I have had this same thing as seville009 happen to me in my '11. Just recently a couple of times? Quite concerning. It seems to happen when the transmission is up to temp but then shut down for a few minutes or longer. I've had it happen after a refuelling stop and then pulling back onto the highway unladen. And I've also had it happen after my truck and trailer has sat for about 3hrs or so, again just the initial up shift hanging in 2nd.

Fluid is fresh and full. 215,000kilometres.

 

IMO...While Im not a huge fan of the shift strategy on the 6R140s (I have a 2011, 6.2) none of this is what id call normal or acceptable. Harsh up shifts, flare shifts or abnormally delayed hard shifts are not normal. Before you give into that "normal" theory have the trans controller read for any pending codes. Have it road tested and pressure tested by a well known 6R140 ATRA cert. tech. Look at the fluid and pan magnet.
Mine shifts into 2 way too early if you drive it like grandma. If you roll through a stop sign the speed sensing looses it s mind and the truck bogs between 1&2. If you put it into tow mode it definitely provides a better 1-2 upshift but with no trailer I dont like the downshifts. Most of the time I manually shift this truck. That puts the upshifts right where they should be. Now when highway towing in tow mode and you go to pass....yikes... the dam thing wont up shift out of 4th until I let completely off the gas(not good at 70 with a rig on you azz). I havent let it go to the rev limiter for fear of rods exiting the pan, but 5-6 grand is not acceptable especially with the large hysteresis between letting off the pedal and the upshift GAH, scarry! Im looking into a tune for this trans. Some have a tune and say its a completely different truck. The factory tune absolutely SUX! Its designed for max economy not anything else. And Im sure thats not Henry's fault its the EPA and big brother.

Bottom line, have it looked at by an ATRA cert shop. Let them tell you whats normal.
The 6R140 is a bullet proof trans, but it can still have a few quirks. Lets hope Ford doesn't go through with the 6R100, or is it too late?

 

When you think its about to shift hard, try giving it more gas, instead of less.

 

To clarify in my case my truck is custom tuned and the only issue I have is this occasional, like once every blue moon, hang in 2nd, when it shifts it seems like a normal shift to me. Only piped in because it sounded similar to what seville009 was describing. For me it's never in first, only ever happened with 2nd and so infrequently that I'm loathe to pay someone to diagnose a symptom that might only happen once every 3000miles. I have just been monitoring my fluid so far. None used, and unburnt.

I only drive this truck in the summer and atleast half the miles are towing. Often during the unladen miles I drive the living hell out of it. I just like to is all. Always have. When it breaks.....I will fix it.

 

My 2016 with 6.2 & 4.3 seems to shift hard from 2 to 3 first time in the morning or leaving work. No other gears. Will do it 90% of the time. I agree with a previous post in maybe giving it more gas. It happens in the driveway ( we have a 1400' driveway) or the parking lot at basically an idle or just above. The truck has 7000 miles on it. Have not talked to the dealer yet. Sounds like it could be more than an isolated problem.

 

Mine does not do the 2-3 slam but if I am doing a slow steady 30 mph it gets in a pickle switching back and forth from 5-6

 

So im haven the same issue truck has just about 138k on it just had it serviced cleaned fluid and filter whatever else trans service may intale.. called a dealer and he says based on that info may be burnt clutches... idk it shifts fine once it gets some heat in it and up to op temps... gonna put a scanner on it hear soon see if it has any history codes on it and maybe call a stand alone trans shop from there..

 

What year? My '11 also does the harsh 2-3 shift, primarily when in tow/haul and heavy acceleration. I had it re-flashed at my local dealer and curiously it was improved, but by no means solved. '11 was notorious for needing solenoid packs in the real early ones and just a re-flash on the later ones.

I have not heard of these problems in '12+, but that doesn't mean anything.

I've come to learn to just drive in M when towing anywhere in the range of 2nd gear, but it's a bummer because I'd be hesitant to let anyone else tow with it.

 

mine is a 2015 and only dose the harsh shifting when cold first couple shifts improves as temps rise once to op temps shifts great
