2014 Advanced, 3.5 weird surging when accelerating
I have this issue where when starting from a stop, there are surges in power, and the tach is indicating a "pause" when it is doing it.
I have had the transmission fluid flush and SW update done, thoughts?
The car has around 45k miles on it.

Try a bottle of Lucas Upper Cylinder Management aka Tune Up In A Bottle. I had a little lag myself when using the ac in my car. Once I poured this stuff in before a full tank of gas the hesitation from a complete stop vanished. I noticed certain gas affects the car greatly in stop and go driving. I stopped using non name brand 93 octane in my car and noticed a big difference once I switched to Shell V Power and Lucas fuel treatment. The car pulls harder now and has a way better take off.

This is my current mpg at 61k miles on a 2013 Acura TL Technology Package with the 3.5 motor.

The TQ converter can do this when the fluid is worn and upon light acceleration. How many miles since the transmission fluid change? Ever change the trans filter? Mine was doing it bad leaving my house on the way to work on light acceleration and a 3x3 ATF change helped it A LOT.

20k ago on the filter and flush, and I mentioned a problem about 5k ago when it was in to the dealer for service.
Also of note, my 2015 MDX is doing it too, so I am suspecting it is a gas quality issue. We buy from the local Giant Bird gas station chain, which hasn't been a problem before.
Would this be indicative of a timing retard due to octane?

Exactly the problem! It’s the poor quality of gas we have today. Try Shell or ExxonMobil. Over here we have First Fuel Premium Gas so they say. Well I put some in and my TL instantly had hesitation it’s as if it didn’t wanna move like it usually does. Never again! Gonna keep putting Top Tier Gas for now on.

I was having the same issue and here are two things I did today and now the surge is gone.
•Added a full tank of Costco 91 octane. The 10-12 prior tanks have all been Chevron premium fuel. Perhaps their fuel has been bad lately. Unsure.
•Drained 3.75 quarts of Acura DW1 tranny oil from the sump. Cleaned all the crud off of the drain bolt magnet. Added 3.75 quarts of fresh fluid.
My 2013 TL FWD drives like it did when I drove it off the lot 52,000 miles ago. Sure is a nice car, paid it off 4 years ago and hope to keep it on the road for another 10 years+!

Thanks for the tip Georgiey22, I filled up yesterday and the problem seems to be subsiding, but I am noticing issues with the shifts, unfortunately, I can't get it to consistently do it, so the dealership won't do anything about it.

Try a bottle of Redline Fuel System Cleaner. I just used it for the first time and it was an instant change in how the car shifts. Very smooth acceleration.

100% unrelated but how the hell are you getting 32MPG on your TL? I have the 2012 FWD and I can hardly get 24-25 average... sigh. Is this just for the ~30 miles you drove or is that a normal MPG you get?

This was with the Redline Fuel Treatment.
Well I’m always on the highway and don’t go pass 70mph. But that was a treated tank with the Lucas Upper Cylinder Fuel Cleaner so that might’ve been a reason why. On average I’m usually doing 24-25 like you.

My surging continues, suspecting it is the transmission.
Just took my 2015 MDX in with the same issue, it has the same transmission, and has about 5k more miles than my 2014 TL. Service Tech said that the 6 speed transmissions need a flush and refill around every 30k, depending on driving habits. I have a service scheduled for early next month, now that my B1 has come up on my MIL. Luckily, still covered under the powertrain warranty.

I thought we were never supposed to flush these trans... ??? I'm doing a 3x3 in a week or two, along with the trans-filter change. Also noticing the gurgling sound specially now that it's cold...

I've heard that some dealers have a machine that can flush the transmission by hooking lines to the ATF filter inlet and outlet, thereby eliminating the possibility of air entering the transmission (which is the reason the traditional flush can kill a Honda transmission). However, I don't think it's common practice. I've considered trying some sort of system whereby I put the inlet tube into a large container of ATF while the outlet tube drains into an oil pan. Then start the car up, put it in gear, and let it cycle through the new ATF. But I already do a drain/refill about once every 10K miles which I think is enough.
But yeah, new fluid can really make a difference in some of these transmissions. I've never really noticed since I immediately did a 3x3 flush when I bought the car, and tried to keep it pretty sparkly clean since then. I've heard of many guys experience much better transmission performance after even just one flush and refill. Let alone doing a 3x3 which replaces approximately 75% of the fluid if you drain 3.5qts. out per drain/refill cycle.
I swear, you could put vegetable oil in a Honda engine and it would be fine but if you so much as sneeze at their automatic transmissions they spontaneously combust.

HA! Yeah, it looks like they sure are picky. I haven't done a trans change in maybe 30k, I never figured it was part of a normal 10k interval. but it's pretty cheap if you buy the 12pk on amazon (like less than 70 bucks). And that should last for around 3 changes if you do a 3x1 every 10-15k miles. Not a bad idea...

Took the car in to the dealership today. They did the more recent TSB Transmission Software update with flush and fill. No issues on the drive home.
To clarify the issue, after having to live with it for a couple of months, the transmission/torque converter wouldn't lock completely in second and third gear between about 1500 rpm and 4000, resulting in a surging feeling while moderately accelerating. Felt like I was slipping the clutch if it were a manual.

Paperwork states they did the 18-047 SW Update with fluid flush, was covered under warranty. Car has just under 50k miles on it.

Kinuto, does your car fall within the VIN range for the TSB's?

Yes it does. I’m 19UUA8F but I had the TSB done for the clogged external transmission filter done. Car shifts smooth but occasionally it will shift funny at 20mph in heavy traffic if I let off the gas. No sure if that’s the torque converter? I have 65k. Looks like I’ll have to bring it to another dealership since the second dealership keeps saying my car doesn’t need the update. I showed them that torque converter update TSB as well.

If it is doing it consistently, they hook it to the computer, and see if it is having trouble locking up. They send the data to Honda, then determine what to do next. Good luck!
