Well, just picked the truck up from the dealer. Had to pay for the shudder diagnosis which turned up a #8 misfire as well as lesser random misfires on the mode 6 test (no CEL) since it out of B2B warranty. Also brought up the transmission issue I have been having. Virtually every morning when I go to pull out of the driveway, when I put the truck in park it was quite violently slamming into gear, even if I let it idle long enough to drop the neutral RPM's. Service writer was a bit baffled, but after touching base with their driveline technician, and verifying it was in no way similar to how any other F150 engages they were able to locate TSB 11-11-11 which, to me, seems primarily concerned with the harsh 1-2 and 2-3 shifting but also noted the harsh engagement. Anyways, they squeezed me in over night and in 2 days had my parts in and installed (apparently on these trucks they have to physically get the numbers off the solenoids to be replaced as there are a couple options). 3 selenoids tested bad and were replaced under the powertrain warranty. Truck did not slam when I picked it up, looking forward to testing tomorrow morning!

Oh, and the best part is that when the tech went to drive the truck in this morning to start working it not only slammed into gear for him (verifying my concern) but it also demonstrated the violent 1-2 upshift. Too bad they couldn't push a spark plug through warranty, guess I'll have to wait for my Rockauto order to come in

 

Let us know how it all plays out when you're rolling again.

 

Well, it slammed into "D" again this morning. Not as violently as it was, but still quite. Didn't give it much chance to warm up, but the idle was only around 1200 or so. First couple shifts were a little sharper than normal, too, though so I'm wondering if the trans is still in the relearning curve.

 

Interesting. It's possible that it's still relearning, but I doubt it. Brand-new trucks on the lot don't do that, so why should yours?

Warming up has nothing to do with it though, there is no requirement for that. My truck has never been given time to warm up; whether it's 3° or 73° it gets put into gear within 2 seconds of staring up and off we go. I don't consider mine to shift harshly, but it's a subjective thing. Perhaps it's normal?

 

Well, its definitely not normal compared to other similar F150's.

 

Sounds like a trip back to the dealer service department! Good thing you're still under warranty.

 

Out of curiosity, why are you not letting the truck run a bit longer to circulate the oil in the motor before heading out? Is this not needed with the newer trucks or something? Does it keep oil in the important spots for start up?

 

I try to give in a minute or two to get the oil into all the passages but beyond that these engines and oils these days don't require a full warm up. Sometimes I'll give it a little longer if its real cold out but mostly you can get in and go.

 

I've never seen any evidence that it does anything helpful. The oil filters have an anti-drainback valve that keeps oil on the top end of the engine. Even if that valve fails, the most people hear a noise for is about a second. The flow rate for an oil pump is measured in gallons per minute; full pressure reaches the heads in seconds even during the coldest weather. It's virtually impossible do cause damage from lack of lubrication unless you run the engine out of oil.

 

Hmm ok well that makes sense...so I will greatly reduce my remote start time then. I have always let all my vehicles at least run a few minutes to circulate oil so with this one I will not waste as much fuel...thanks.

 

I have a 13 5.0 and when warming at about 1200 if I put it in drive to move out of garage does not slam even a little and idles down to 800 or so my tranny is smooth as glass in all gears maybe ford tweaked it a bit from original

 

I am glad that I get on here to read these forums, it shows how much I don't know about modern vehicles. I think that I am so used to a warm up from all of my older push-rod style motors. Well now I know! So thanks!
