I got to the state of deleting all the errors and went for a ride. When starting the car, something tugs at the back, (ABS? MOST?) Turns on 1,2,3 gear reaching 30 mil ejects as if in neutral gear, when the speed of rotation of the wheels returns to 20 mil, the gear returns and goes on, errors after driving are:
86-1, U0114, 84-1, P0756 (71-3), 84-1, BUT ON THE MAIN DISPLAY OF THE CAR ONLY 1 ERROR 2703. If you have any idea what it can be, please give me a hint.

 

Are these codes on the nav screen?

Guys, on the RL when I was coming out of a parking lot, I stopped, saw a car coming but it wasn't that close, so I gently applied gas while turning right, then applied a bit more gas to pick up the speed. It felt as if the car stayed in a somewhat higher gear, the speed slowly increased(should of gotten more speed) and tachometer was going towards 4K or bit more and after it did, the car gained appropriate speed. Is this normal behavior for 2010 RL or transmission is acting weird?

 

So... downshifting delay.

How many miles on the car? And did you check transmission fluid level and color? should be quite pale nothing dark. Check when it was last changed.

I've been recommended to change the transmission speed sensors. There's 3 of them. ppl seem to be doing it once, as half-life maintenance.

 

Car has a bit less than 110K. Transmission is clean, good level. Engine oil is clean as well at 100% life as it was replaced a week ago.
I have re-tested today and it seems that I wasn't giving it enough acceleration. I have tried to do the same thing as I did yesterday but this time instead of 30% or so, I gave it 45% gas and car just goes quickly and after 4000+ RPM it takes off even faster. VTEC kicks in? I think I need to get used to the car, as I came from my fun to drive 2016 MINI Cooper S which has turbo charger that kicks in in 1600K RPM or so.

As far as "transmission sensors" I have no idea what they even do

 

I've had the same thing. Unless i press more on the pedal, the tranny won't downshift fast enough. Which relatively and proportionally to my feel of the pedal in general sriving, this much pressure should be enough to downshift, coz i also dont wanna jump suddenly to higher speed.

The transmission speed sensors are new to me too. they seem to control when to shift. Coz there's 3, and the tranny is 5 speed.

Also, the pedal isn't pulling on any wire. It's a simulation with resistance and a sensor. Sensors go bad. I seriously doubt its this at 110 Kilometers, but maybe...

Projekvrtx said ppl usually change them as maintenance. seems you do that once in the car's lifetime. Maybe twice is very bad cases. I'm also considering changing engine mounts.

 

Some of that slow reaction to the throttle might just be calibration you're unused to. It's always been noted by reviewers since the RL was new that its controls, including the throttle and steering, have somewhat muted reactions compared to the TL in order to convey more of a luxury impression. Of course, at this point in your car's life it may have problems as well.

 

110K that I mentioned were miles. Spot on about giving more gas. The transmission wanted me to give it more gas and I was't doing that. I need re-adjust my gas pedal presses as with 2.0 turbo MINI Cooper I stepped on the gas a bit and car was already going 40 without any sweat. With RL, the power delivery is smooth until about 4K RPM, then the gas takes off and then becomes unstoppable

 

I think there was some kind of article that RL's transmission(possibly on other models too) had some kind of a chip that could learn the habits of the driver and re-adjust accordingly. Am I missing something?

 

The joy of VTEC, dude.

 

Most modern automatic transmissions, including the RL's, have the ability to "learn" the driver's habits and adjust the aggressiveness of their shifting accordingly. But I was reading a while back an explanation from somebody who understood this technology much better than I do, and he was explaining it adjusts the shift behavior within a rather narrow range of parameters. At the bottom line, the basic rule still applies even in these modern cars: if you really want to take off, mash the right pedal.

 

I see what you're saying. Certainly reassuring. thing is when you've drive for so long, and also the same car, your sense differentiate what's unusual. I have a feeling maybe even a loose screw on the pedlal, like if there's a bit of a gap when its depressed, but i dont know.

Is there a test one can do for the tranny sensors to know if its that or not?

 

correct!!


Imperial has to get used to the engine's characteristics. the engine makes peak power at 6500RPM. this means you need to rev the car all the way up to get any kind of power

 

Probably not. You can pre-emptively replace them (a few hundred bucks—I wouldn't do it). The car checks them on an ongoing basis. If they start to fail, "D" blinks and it flashes you a trouble code.

 

I recently read a post for TL which indicated some sort of transmission reset. This will make the transmission learn again and possibly will increase responsiveness.

 

Don't expect too much from that drill. All it will do is possibly make shifting a bit more or less responsive to the throttle.

 

Maybe it is a good idea to clear the memory from previous driver unless the system will re-learn my driving habits too.

 

So I did try the reset, the only thing I found one for TL or Acura in general. Some state turn key to position 2, hold gas pedal for 5 seconds, others 30 seconds, then turn off. After that start the car and do road test. Anyone has tried this on 2010 RL or similar and knows the steps?

 

Last time I did that my carburetor chocked

 

Yeah Yeah it's really hard to compare a 4000 pound luxury Sedan to a 2000 pound miniature race car that's turbocharged.. The J35 motor has a nice torque ban so before the Tech you can give it little spurts to get around traffic without flooring it.. But once V tec kicks in it gains about 35 to 40 horse power.. Sounds normal to me my friend just need to learn how to drive your vehicle..

 

Right, I am getting there. The engine feel lively and seems to have enough power haul around heavy RL. When VTEC activates, I feel like I am in the Jet, getting ready to take off

By the way, I opened air filter box and saw dirty air filter + it wasn't installed properly. Ordered a new one. Don't know how Acura techs could of missed this when I was purchasing the car. I also found a bolt sitting under right engine cover on top of the right strut mount. It was from A/C H line and that metal tube was pretty loose and had to be tightened. Good that the bolt was just sitting there. Looks like this is how "their 70 point inspection" is done!
