strange lunging behavior of the transmission

[1stSFG]

Huck is spot on. My truck does it. It's like a "choke" setting. Until normal operating temperature is met it stays in that "high idle" air restrictive mode. And the throttle response it brutally sensitive. In manual shift mode, the throttle response is the exact opposite.

I had the same shifting problem back at around 40 000km on my 2010, turned out to be the valve body (had it changed under warranty)... Now that i have near 80 000km it seems to be starting up again with the same problem.

There's a way to have real time data display on the productivity screen while you're driving. Watching the rpm, digitally, might show if the motor is surging. Maybe someone recalls how to set-up that display?

That reminds me of something... In the truck aps, the gauge mode setting has only the trans temp on mine. Shouldn't there be other things like oil temp, water, rpm, speed. There is another page on mine but it is blank, is everyone's the same or is my shit broke?..... Lol

Double checked for this today and my 2014 with 2,000 miles does not do this when the tranmission temp is <80.

Thank you for the info, GitErDunn. Please send me the info previously requested; I’ll assess the next step.

I meant to make a query about this myself. This morning I was going into town from the rig and decided a slow cruise with tunes on was in order as it was a beautiful summer day I was watching for wildlife. The SE reminded me, again, what crappy throttle response it had and I had noticed this before. I had a "last of" mechanically injected 911 Porsche years ago that did this. Turned to be "altitude" related issue and after it was dialed in for 4000ft ground level was great so I assumed this too was a fuel metering issue. I appreciate the diagnosis and will try again once truck is completely warmed and see whazzup. EXCELLENT! Thanks guys. I love this site. "The Ole Pebble Pimp"

Mine does it too...seems normal until truck comes up to operating temps...I will say running a tune did help somewhat...

Although, with a ****** truck could NOT. Hurt to have the dealer look at it and documented in your records in case it is at Randy or another issue...

Mine does it too first thing, but weirdly i was sat in traffic the other week for c45mins crawling mostly sub 10mph and it did exactly the same thing with the trans at 187f...

Its going in to have the pinion seal done next week as its leaking like crazy, think I will get them to look at the trans...

Waiting for the Ford Techs to say Pinion leak is down to the new rear leafs and not covered on warranty (2012 SCREW 17k miles Full service history)...will see! (Especially as pinion fix booked in before the leafs were added...have proof)

Guys, my truck does this as well. Huck is right on the operating temp issue. Let it warm up longer, or get a custom tune. Either one of these will resolve the issue.

my 2010 acts like a drunk moron until its warmed up. Nice especially when right outside my driveway is a huge hill to go up thats 55mph
