Shifting the 2008 Accord EXL auto like a manual
Hello,
I have a 2008 Accord EX-L and its an Auto. Everyone now and then I like to put the car in 1 at a red light and shift up to 2 at about 4500 rpms and then to D3 at about 4500 rpms etc. I am wondering if this upshifting and downshifting practice is bad to do? I make sure that I don't put the gas on until the transmission has caught the next gear. I wouldn't think so, but wanted other opinions. I know what everyone is going to say "Why didn't you get a manual transmission??" Well the fact is I only like to shift every now and then, so I would fall into the weekend shifting enthusiast category, and unfortunately I cannot afford to have two cars, so I have an automatic transmission car. Thanks, Al |

According to the Owner's Manual: "To shift from Second to First, press the release button on the bottom of the shift lever. This position locks the transmission in first gear. By upshifting and downshifting through 1, 2, D3, and D, you can operate this transmission much like a manual transmission without a clutch pedal." Have fun. Just make sure you shift below the redline. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

Both seem to know about Honda's but since Tegger's information is like the manual I would tend to believe this. Also wouldn't shifting the auto manually be like using the sequential sport shifter in the acura's for instance? Either way theres no clutch. |

Is there any particular reason you believe an Internet poster over the Owner's manual? It simply amazes me regarding the number of posts made (not just here but other car boards I am on) with questions that can be answered simply by looking in the Owner's manual. Or by people second-guessing the Owner's manual. Here, I will tilt the balance for you: it's okay to shift it manually! Don't confuse your automatic transmission with an 'automated manual' transmission. Yours is an automatic that you can shift manually, if you desire. An 'automated manual' - such as that found in Audis, Ferraris, BMWs - is a true manual transmission with automated clutch operation that can be asked to shift automatically. They are 2 totally different animals. Dan D '07 Ody EX Central NJ USA |

The product of that thinking is below. In a Honda automatic transmission, shifted automatically, the transmission computer (TCM or PCM)decides when it will trigger the shifts. It makes its decisions based on many factors, chief among them being: road speed, engine speed, engine coolant temperature and throttle position. The PCM effects automatic gear changes by powering/depowering the various transmission solenoids (and there are many of them) necessary to engage/disengage particular gear ratios. Operating the shift lever manually means that you -- and not the computer -- command the solenoids to operate. Placing the lever in "2" for instance, causes the shift solenoids to assume the identical same positions they would had the PCM forced the shift to "2" itself. Either way the transmission responds in an identical manner using identical parts, and will engage the new gear with identical vigor. In other words, the same parts are operated to change gear whether the PCM gives the signal via its logic or you give the signal using the position of the gear lever. Honda did not install two separate sets of transmission control mechanisms. I can see just two possible problems with shifting an automatic manually. These problems a overspeed of the engine, and "lugging". In a manual transmission there is nothing to save you from catastrophic engine failure should you, say, shift into second and let out the clutch at 85mph. Even though the engine's ECM will have cut off fuel near redline, the solid mechanical connection between engine and road wheels will pull the engine into mechanical failure territory and a rod will poke itself through the block. Likewise, if you choose to shift your manual 5th at 10mph, the engine will labor mightly to keep the car moving, pounding the crankshaft and rod bearings oval in the process. In an automatic the PCM constantly monitors engine and road speed, even when you shift manually. I would *think* the PCM would block the manual gear-change signal from reaching the solenoids if the resulting engine speed would exceed redline, but I have never tried this, not having a disposable car to test on. With an automatic, if you put the lever into a lower gear and repeatedly forget you've done so, you'll be running the engine at a far higher RPM than the PCM would run it at, leading to greatly increased engine wear. Remember that moving the lever to "2" locks the transmission in that gear. It is therefore possible to overheat and damage the transmission and its fluid due to lugging at low road speeds in too high a gear, provided you lug the powertrain for long enough. It is interesting that the Owner's Manual mentions the engine speed limiter (present on both models), but has a caution ONLY for the manual transmission model. The manual transmission caution warns that the engine speed limiter only works on upshifts, it does not work on downshifts; you are warned to make sure you will not exceed the engine's redline when downshifting. Plus there are tables indicating maximum speeds in gears. The automatic transmission section gives no such warning and has no speed tables. This implies that the PCM will protect you from major stupidity. Elmo's warning has truth to it: When you take upon yourself the responsibility of choosing your own gear ratios, you also take upon yourself the responsibility of knowing something of the machinery of your car, and the damage you may cause by manipulating that machinery incorrectly. Maltreatment of the equipment is called "abuse". Honda will not honor warranty claims resulting from abuse. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

I am still wondering if a sequential sport shifter like in the Acura TSX would make the car faster than using the regular auto mode? I wanted to say that although the manual shifting can be fun, I don't think that it really works that well with the car for performance. Today I thought I would try a test against a Kia Amanti using the manual shifting method in my 2008 EXL Accord Auto. I had trouble keeping up using the shifting method. Then at the next light I put it in D3 and my rpms hit about 5500 rpms I and blew the doors off the Kia Amanti. So maybe its just better suited that way and should only be used to control the revs or slow down faster etc. |

Just make sure you shift below the redline. 1. the only "fun" alfred ever has is finding things to worry about. [and bleat on newsgroups about.] 2. it's impossible to manually abuse that transmission. it's all electronic, so the ecu won't let you shift in a pattern that'll harm anything. |
