Anyone had their transmission simply not respond, when flooring it?

Anyone had their transmission simply not respond for a longtime, when flooring it?
I was on the highway recently, and was merging into traffic from a near-standstill (as is normal).
I was half out of my lane, with high-speed traffic in the lane I was merging into, and floored it while in D mode to merge into the lane.
Simply nothing happened for SEVERAL SECONDS(like 3 seconds). It seems like I lost all wheel power. Not even slow movement while turbo spun up -- simply 0 power.

After those few seconds, the vehicle finally started accelerating. I didn't move my foot so no, I hadn't been accidentally pressing the brake

Anyone had this before?
Is this a transmission issue? Engine issue? Either way it was extremely unsafe.

I had what you described when my transmission place installed a broken gasket/seal and the fluid level was not right.

Do you always - Quick Punch it to the Floor?
Did you Steer Left / Right - More Than Normal?

Good thoughts and good questions
Yes, this is always how I merge into traffic from a standstill -- never had this before.
Unfortunately I don't know if it was a sharper steering angle than normal..

Was it like flooring it with the clutch in for 4 seconds then side stepping it?! How was the burn out?

I know this was in jest but there was no burnout: when it started, it finally accelerated normally as I would have expected.

I have had this happen several times. Usually it is when the vehicle is cold, or just after start up. I will put it in D, slowly roll out of my spot and putz through the parking lot/my driveway whatever, and then when I start to get on the gas nothing happens. I am always still rolling a bit when it happens, it has never not moved from a complete stop. I am not flooring it by any means, maybe 1/4 throttle for normal acceleration. It is as if the throttle is completely disconnected from the pedal, no RPM change regardless of throttle position. When I push the gas and it doesn't go, instinct makes you push it more, still nothing. A few times now I have even repeatedly floored it with no result. Timing is tough to gauge, but I have enough time to pump the gas like I am starting a carbed car from the 60's before it finally "wakes up" and resumes normal operation. I would say 3ish seconds, which is a scary amount of time when you are pulling out into traffic! I am very familiar with turbo lag and this is not it. I have learned the conditions under which it exhibits these behaviors, and I purposefully try to repeat the symptoms, but I have never gotten it to do it on purpose. It seems totally random.

I took it to the dealer and they obviously couldn't recreate the problems either. This issue along with harsh downshifting made me do an early trans service at 40k miles. I had the dealer do the trans fluid and filter, as well as the transfer case and diffs. About a $900 service. When the problems didn't clear up I brought it back in for them to test drive. They couldn't recreate the issues and my service advisor said "your fluid looks low and dirty, probably hasn't been changed in awhile so we recommend doing that service." I was like uh buddy take a look at my history, I had the trans service done 6k miles ago. That shut him up quick. They continued to drive it, still couldn't get it to act strange and ended up topping off the fluid and sending me on my way, all for free thank goodness. I was not impressed to say the least. For anyone out there with trans issues, especially on the trucks pre CDF update: DO NOT CHANGE YOUR FLUID, IT WILL NOT HELP WITH THE ISSUES AND WILL ONLY COST MONEY YOU NEED TO BE SAVING FOR YOUR NEW/REBUILT TRANS. This is more related to the harsh shifting and hesitation issues, not the complete dead pedal issue. I think that the pedal issue is a programming one, not a hardware problem.

After I had the Ford tune installed, engine braking has been far less and my truck coasts far more now. It's pretty obvious so you don't feel that downshifted decal any more.

Has anyone had any issues with a delay when shifting from drive to reverse?

I'm only 4.5 miles from work and I normally drive with tow-haul mode on as the Rangers transmission will shift to 7th gear if I don't (which is too high for 30 MPH - IMO). The speed limit at most is only 35 MPH.

I'll pull into my driveway sometimes and wait for traffic to clear; then back out, turn around, and back in. While doing this there is a delay of 3 to 5 seconds when I shift from drive to reverse. I know this isn't a long time, but when you have a vehicle come around the curve in the road about a half mile away heading at you and not slowing down. When this happens I will push the pedal (sometimes to the floor) as the truck isn't moving and when it decides to move, the rear wheels spin.

5 sec is way too long. Don't hear too much issues regarding reverse, but man these 10R80 will come back and bite Ford later down the road when more of them fail. It will expose their defects and short comings.

Mine is only slow backing up on a cold morning when I first pull out of the garage.

I'd almost go for a tune just to get the transmission shift points optimized. I don't want more power, but I do want more reliability / drive-ability. I dislike the engine braking that goes on when decelerating to a stop.

Sounds like a sticking solenoid in the throttle body. Last year my forward shifts were taking seconds to complete, and I could actually hear the solenoids transitioning if I listened carefully.

I cured it and a host of other crazy behaviors by changing the fluid and adding a bottle of LubeGard Platinum. I sucked the old fluid out with an inexpensive transfer pump into 2 plastic milk jugs. With 1 quart marks added to the jugs before beginning. I put exactly the same amount back in, 7.5 quarts. I let the truck sit overnight to get maximum fluid out

Then refilled it. Got rid of 99% of my issues with the transmission.

I've experienced something like this - I think? once. Off the highway to a stoplight for a right lane yeild/turn, foot off the brakes to the gas and nothing for a couple(?) seconds. No motor rev, no transmission engagement. Lifted off the gas while checking for dash indicators (none) and back on the gas and after a slight delay off we went. Never happened since though I had the dealer change the trans fluid. Which according to the MBS trans lipstick was perfectly filled.

So what about changing the oil remedies this in your view? Just changing oil shouldn't have any measurable change.

This is exactly what the tune does.

I don't think the transmission service had any effect - it was something I had planned on along with adding Lubeguard anyway. My perspective was this wasn't a mechanical issue but possibly a sensor reading/software glitch. Never happened before or since and I bought my truck new.

What happened to the OP?
