I was driving my car a little hard the other day in auto mode (no paddle shifters).

Floored it in second gear to pass a Parking Enforcement Prius that was blocking the road, and once I hit 7k RPM, the car wouldn't shift up...it just kept bouncing off the limiter. I was NOT in manual mode.

I then put it in manual mode and tried to shift up. Nothing happened. Gear indicator just stayed solid at 2 (Usually when I try and shift down and the ECU doesn't let it blinks).

I ended up having to put the car into neutral and back into drive, which alleviated the situation.

This happened to me a long time ago on the freeway when I first got the car as well, but I forgot about it soon after.

Anyone know what I'm talking about?

The computer must have had some reason for refusing to upshift, but I'm not sure what that reason might have been.

Something similar happened to me once. I was driving down the street and thought I was in sport shift mode but I actually wasn't, so when I tapped the shifter to upshift I actually put it in neutral, which caused the rpm to go way up because my foot was still on the gas, then when I realized what I did I instinctively without thinking put it back into drive without letting off the gas, and that caused a big thump. After that, the transmission wouldn't upshift into 4th gear, I was in 3rd gear accelerating slowly and the rpms kept going up but it wouldn't shift to 4th even though it usually shifts to 4th at just above 2000 rpm if accelerating slowly. So then I came to a full stop, then started driving again, and this time it upshifted fine. That was several months ago and I haven't noticed anything strange since then.

Perhaps doing certain things (like driving at high rpm or doing a neutral drop) causes the temp in the transmission to go above a certain point and the computer will not allow an upshift until it cools down? This is just a wild guess, anyone know more?

Inaccurate

It happens. It has happened to me about two or three times. The last time it happened, mine eventually shifted on his own. I was doing warrior battling in rush hour traffic... wot, no prisoners. I just let it bounce off the limiter, wot, until it finally shifted on it's own.

07 transmission oddity. What could have caused this (click here)

Yah, there has been a couple of threads on this.
The consensus seems to be that under full acceleration in second gear, and a loss of traction seems to confuse the computer.
Probably some kind of fail safe mode. Haven't seen where anyone has suffered any long term problems from it, though.
It's happened to me once only in 72K miles.

Happened to me once. Car wouldn't shift up from 2nd gear. I was at redline for a moment to see if the car would shift and it wouldn't. But yeah... never happened again.

It happened to me before while merging onto the freeway. A week later w/o doing anything different while just driving along the freeway going posted speed, the car wouldn't shift at all! (almost like a clutch slipping) I put it in sport mode and it shifted once but then continued to just rev w/o any response. I had to pull over on the freeway and get it towed to acura. they replaced the whole transmission. But the both times i asked the service writer what went wrong with it they just said they dont know but it has been replaced. i'm scared to drive it hard after that.

This exact thing happened to me this morning. I have a 07 Type-S with 27K. Has anyone called Acura regarding this issue??

theakman

I had the same thing happen to me a bunch of times with my 08 Type S.

Funny thing is last time it happend I took it into the dealer and they said they saw the problem and they called tech support to see if anyone else was complaining about the problem too.

They gave me car back and said to drive it until they heard back. When I picked up my ride I noticed that I was overdue on an oil change so I had it done by them before I took it home and by miracle the problem was gone.

The next time it happend again it was just about time for another oil change so I took it for the oil change and again the problem went away.

I have no explanation why changing the oil fixed this problem but its worth a try.

Brad29

I just took my Tl-S to the dealer for some warranty work and asked them to look into this issue. I explained the situation to them and they said they would run a diagnostics test on it. They called back later and said they could not find anything wrong with the transmission.

Warranty work was for the light on the heater switch in the center console.

OP

I had the same issue...

Went to the dealer, and they've replaced my tranny... it happened around 30K

According to them it was the 1st ever happened to them...

They gave me 4G TL loaner for 2 weeks...

shadowkahn

I'm surprised they replaced your tranny. I'm guessing that won't fix it, as they didn't rewrite the transmission's software.

Bearcat94

As far as you know.

2 weeks is a pretty long time. Our 2G tranny replacement took 2 days.

shadowkahn

Well, presumably if there were a software update from Acura, someone here would know about it, and all of us who have had the car lock into 2nd gear would then be able to go and get the upgrade. Since I've not heard anything about a new version of tranny software, I can only assume that they're replacing the hardware, but leaving the software alone.

CometVR4

It happened to me also.

First time I was getting on the highway. It was when I first bought the car a few years ago and thought it some some type of gear hold mode. But after driving a couple miles in second gear it wouldn't shift despite my efforts to use SS mode. I dropped it down into L and slowed down and then shortly after it shifted fine.

The next incident happened once again a couple years later merging around a slow moving semi getting onto the highway on wet streets. The car broke traction for a second (TCS was on) and then it got stuck in second gear for a short time.

Bearcat94

Right, fair enough.


It's just hard to know for absolute certain.

There are TSB's at this link. Don't know if there is anything on this tranny.

IMO, this is nothing more than a glitch, and is extremely rare.

The conditions under which this happens are similar, and I believe nothing more than the transmission going into a fail safe mode. It doesn't know what gear it is supposed to be in for a minute

Mine has done it once in 74k miles, and have not had another problem.
I wouldn't stress over it, or expect Acura to address it.

I mean, how long did it take them to acknowledge a REAL problem with the
2nd gen. tranny, which was much more common and serious?

I hate cars

Same here. Temporary loss of traction, car won't shift out of second gear. It did this 50,000 miles ago and has been fine ever since.

Acura is very slow at reacting to issues. There's the pinging problem that they deny. The 2nd gen serious trans issue that they denied at first. There's this issue.

They will throw hardware at software issues. They don't troubleshoot but instead replace parts.

Ever wonder why many of the cars that had a trans replaced had it replaced again? They don't address the electrical problem causing the mechanical problem.

for what it's worth, in my 01 Acura CL-S, i had some odd tranny issues, (50kmiles or so) which Acura attributed to faulty tranny. But problems occured after transmission was replaced. Basically, it wouldn't shift into next gear, so it would sit in 3rd or 4th on the highway.
I got the throttle positioning sensor replaced (at around 65k miles) and never had a problem for the next 40k miles or so, and then I sold the car.

2nd gen (2001) was a totally different transmission, with its own unique set of problems (unfortunately)

Hapa DC5

Just had this happen to me this morning. I'm almost at 67k I think it might have happened to me once before in the past as well, but I could be wrong.

I was merging onto the freeway and I never use SS mode. As I stepped on the gas (maybe a lil more then half throttle) the car downshifted into neutral and I almost hit rev limiter. I let off, stepped on the gas again and the car downshifted fine.

I had to do a search to see if others experienced it as well.

Soseductivesf

Hmmm i have a problem on my 08TL-S.... It seems to upshift by itself... mainly 3rd to 4th..

This seems to be a common enough problem to grab Acura's attention.

NetGnome

This just happend to me as well. 08 5AT base. Acura could not find any problem. Tranny just stuck in 2nd gear. Shifting to neutral resolved it.

tomkocz

wait a second - you folks never heard of the notorious Acura transmission problems?? I have a 2003 tls and on its 3rd tranny - and now needs another at 127K - car is worthless. Acura replaced the others and extended the tranny warranty to 100K miles but now they say they will not replace for free. I will never buy another Acura. I have owned over 10 cars and never replaced a tranny. THis car is worthless - and if they replace it guaranteed you will need another in an=bout 30K miles.

I hate cars

We've found and cured the problems assiciated with the 5at. 3rd and 4th gear switches every 60K and Redline Racing (type F) fluid. Pretty much makes them bulletproof. It's brought several back from the grave.

Many times when they replace a trans, they carry over the old switches which causes rapid wear on the clutches and another quick failure. It's sad that Acura did not discover such a simple fix. The Z1 make the issue much worse since it's loaded wtih friction modifiers. Even the 400hp turbo TL is holding up great with the only mod to it's 5at being the type F fluid.

IHC-This is a little off-topic, however I was wondering if the 3rd and 4th gear switches and the Redline ATF applies to the 98-00 Accord transmissions as well if it is starting to slip?

freshbwoy_CLS

I have the same problem as stated by #21, any solutions to the transmission shifting by itself from 3rd to fourth in Manual Mode. TLS 07.

csmeance

Have the car scanned via Honda Diagnostic System and see if you can pull any codes. On my MDX, when the 5th Gear Pressure Sensor died it did something similar where the car wouldn't go into 5th in D mode, but it did go into 5th by itself in SportShift Mode.
