Transmission Problems

[banjos-n-beer]

They might be right, then.

I'm just thinking that when you don't use the EB, you brake and shift, so it seems you'd add the EB after that. As long as the wheels don't turn between putting the tranny in park, and locking the EB, the shift pawl shouldn't see binding forces.

If you use EB before shifting, the shift to park might not let the pawl move all the way into position. That's supposition, as I've never seen the inside of an auto tranny, just cycles.

I'm not an expert... that's why I come here for advice. I can state that when engaging the EPB before shifting to park, there is zero rolling after shifting to park and then releasing the foot brake pedal. That's why it is quite confusing that I still notice the resistance upon start up the next time. I'll still give your suggestion a try tomorrow. Left the CX5 home today.

I disagree about Sport Mode being useless. Sport mode puts you right in the powerband so you have the best possible response from the engine. Without using sport mode, you have to wait for the car to be in the right gear before it will take off. With Sport Mode on, you're already in the right gear.

Take for example, merging into a highway with a slow car in front of you. Without sport mode on, you have to wait for the car in front of you to get out of your way so you can get up to speed. All the time, you can't get on the gas until you have a gap and then you bury the throttle and you wait for the 1-2-3 downshifts (depending on speed) until the car takes off. With sport mode on, the car is in the right gear while you wait for the gap, once a gap is available, you punch the throttle and take off.

It is relatively useless from a stop because you're already in the right gear anyway when you're stopped. You'll start from 1st gear regardless if sport mode is on or not.

Sorry for being off-topic but I feel like people just don't understand when to use sport mode and like to bash on it.

So you can wait for the downshift, or wait for your hand to reach over, and flick a button, and then give it the gas. Or you could slap it over into manual and select the gear yourself.

Sport mode uses the most fine-motor control skills. Not something I like for something like a dynamic situation.

Yea, me either...

Ive always shifted to park then put the park brake on (electronic or otherwise) before lifting off the foot brake.

Either way you do it, IMO you want to avoid loading the auto transmission up before the park brake takes effect.

This is what I do all the time too. The key is you keep your foot brake all the way until you complete all the the necessary steps - shift to Park, and pull the EPB. The vehicle won't move so as the position of the parking pawl related to the gear tooth. It's possible in certain situation the parking pawl won't be fully locked into the tooth but it won't affect the operation of shifting out of the Park before you release the EPB. The parking pawl will lock up the gear tooth on the output shaft to hold the vehicle. EPB should always be applied to relief some pressure from parking pawl while the vehicle is parked.

Or you can turn on Sport Mode as you're entering the on ramp and you're already in the right gear. Why wait for downshifts when you have a mode that allows you to be in the powerband already ready to take off? Why would you need to go into manual shift mode, when you have a mode that allows you to be in the powerband already ready to take off?

I don't understand the fine-motor control skills comment. Does that mean that wanting to use Sport Mode makes you less of a driver than others on a road?

Or you could pay 100% attention to what's in front of you while: Turning, merging to the on-ramp, calculating traffic flow on the freeway, and noticing that slow driver in front of you, not trying to jab the brakes and get rear-ended, etc. and just use the accelerator. If you can't wait for the accelerator to work and the transmission to downshift because "it's too slow", can you really afford to be in a 2017 CX5 that's a full HALF SECOND slower to 60mph? Something to ponder...

Fine motor controls are the first thing you have issues with in a stressful situation, and they can draw your attention, create tunnel vision, etc. This is why Glocks do not have non-passive safeties.

I have often wished for a bit more power, but never a "sport button" that does nothing but lug the engine around a couple of gears lower than typical. Some sport-buttons firm up shifts, raise line pressures, and adjust suspensions. Those are useful for things. This? It's just...I dunno...a doodad? Most vehicles call this button "The Tow button". Do you see people on the Truck Forums talking about using their towing button to merge onto the freeway? WTF?

I'm a bit of a dork so.. "lug" would be high manifold pressure and low rpm..like driving in a gear unfavorably for your speed. or boosting a car in high gear and zzbb^^. But yea, from my experience sometimes downshifting to utilize and extra 500rpm before fuel cutoff point will give you more output accelerating vs full throttle from mid range fourth. Sport is less useful than manumatic imo.

What the hell is that in your avatar? Is that like a CX5 wearing a Romper?

Anyway, lug is the wrong word mechanically, but a very accurate description of forcing the car around in the wrong gear, IMO. Yes, shifting late and early can help, but honestly, the cars now days tend to shift themselves pretty darn well...

What is the source of this? Whatever I have read points to 7.8 which is ballpark for 16.5 - not sure if 15 was faster?
Full google search 2 pages.
Again - there was little consensus on Mz3 2.5L - Alex on Autos quoted 8.3 which seemed fishy. Forumers say 6.6 - some say 7.

 

[minnesotaart]

Interesting observation after reading all this. Those that favor sport mode have GTs with 19" tires. Those that say it does nothing have Tourings with 17" tires. I have a 2014 GT (so no sport mode) that I run 19" tires on in mild weather and 17" snows in winter. Acceleration from a standing start is markedly slower with the 19s than it is with the 17s. Could be the reason that the Touring folks don't see much difference and why the GT folks do.

Sport mode does nothing from a standing start on a WOT run.

Interesting comments. I also run 17"s in the winter, but they're just black steelies, not aluminum rims. My snow tires also have studs. To me the car feels a bit heavier with the 17"s, and a bit more nimble and spry with the 19"s. PSI is 38 for the 17"s, and 36 for the 19"s (I follow the recommended increase for winter on the 17"s for +4 over regular PSI)

Could just be psychological. But I haven't really done any WOT standing starts with the 17"s on either.

I'm Rollin' on 19s. I don't care for sport mode.

You can turn on Sport Mode without taking your eyes off the road. It is located to the left of the shifter and I can turn it on or off without looking down on it. Being able to turn it on without taking your eyes off the road means you can still keep 100% attention to what's in front of you. You seem to be implying that the use or the act of turning on Sport Mode distracts the driver and lowers their ability to drive. I can tell you from experience it does not.

All of these things that you mention, "Turning, merging to the on-ramp, calculating traffic flow on the freeway, and noticing that slow driver in front of you, not trying to jab the brakes and get rear-ended, etc. and just use the accelerator.", are not impeded by turning on Sport Mode. I actually don't understand how those actions are affected with Sport Mode on.

If you can't wait for the accelerator to work and the transmission to downshift because "it's too slow", can you really afford to be in a 2017 CX5 that's a full HALF SECOND slower to 60mph? Something to ponder...

I think you're just nitpicking at this point. Here is a feature, Sport Mode, that puts you right into the powerband to make the car more responsive, and you don't want to use it because you want to wait for it to downshift? I presented an example where Sport Mode can be helpful. I didn't present an example where not having Sport Mode makes the car undrivable.

LOL I am one of those people who think the CX-5 is slow. I think it could use 20-30 more HP or at least more low-end mid-range torque. While Sport Mode does not increase power, the extra response from the engine is nice to have.

Fine motor controls are the first thing you have issues with in a stressful situation, and they can draw your attention, create tunnel vision, etc. This is why Glocks do not have non-passive safeties.

I still don't get what fine motor controls mean in this context. You will not get tunnel vision when you turn on Sport Mode, I promise. Turning it on does not require a huge amount of brain power or body eye coordination. What I'm trying to say is that it will not make you an unsafe driver on the road.

I have often wished for a bit more power, but never a "sport button" that does nothing but lug the engine around a couple of gears lower than typical. Some sport-buttons firm up shifts, raise line pressures, and adjust suspensions. Those are useful for things. This? It's just...I dunno...a doodad? Most vehicles call this button "The Tow button". Do you see people on the Truck Forums talking about using their towing button to merge onto the freeway? WTF?

You cannot lug the engine of the CX-5 with an automatic transmission. Even more so in Sport Mode. Sport Mode puts you right in the powerband, usually at 4k RPM. There is no way that you will be lugging the engine at 4k RPM. Actually, there's just no way to lug the engine on an automatic transmission CX-5 period. Even if you use manual-shift mode and put it in 6th gear and try to drop the revs, the transmission will automatically downshift to keep you from lugging the engine. I mean there is just no way for the car in Sport Mode, to be in low RPM and high gear, which is what I understand "lug the engine" to be. It is just not possible. How can you be in 4k RPM and be in the wrong gear to be lugging the engine? It will have you driving around in 4k RPM in 3rd or 4th gear depending on speed on the on-ramp, but I promise you, you will not be lugging the engine.

The Sport Mode feature does not increase power, that is simply not what it was added for. Sport Mode puts you right in the powerband, makes shifts snappier and makes the throttle more sensitive. If you are fine with driving in normal mode, which is the only mode available if I'm not mistaken in the 2015 models, then you're golden. However it does not make it useless for the 2016 models and above.

Just because people are turning on Sport Mode when towing, doesn't mean it is a "Tow button". The reason they turn it on when towing is for the extra throttle sensitivity. Meaning they don't want to press harder on the gas pedal to get more response from the engine. They can always press harder on the gas pedal to get more power from the engine if they want to. Same thing when going uphill. You either press harder on the gas pedal, or if you turn on Sport Mode, the extra throttle sensitivity means you don't need to press as hard to get more out of the engine.

----------

I can see manual shift mode possibly yielding faster times if you drop it to a gear that puts you at 1k or 500 RPM below the fuel cutoff, versus Sport Mode with the shifter on D, but I think the differences in times won't be that significant. I mean how long can you stay at 5.5k - 6k RPM to extract power before having to shift to the next gear becuase of fuel cutoff. Even taking into account perfect shifting and not triggering fuel cutoff, which can be jolting, having to manually shift to the next gear will lose you some time versus being at 4k RPM and going WOT from there. If someone can test the differences bewteen these driving modes, I think it would be an entertaining read.

Especially true. You have so many vehicles that offer this in the CX-5 Price range - Toyota Sequoia, Porsche Cayenne, some BMWs etc. Cannot understand why Mazda does not do this.
Sport mode is lame. I have not seen a car under 30K that has this except - Corolla iM, Nissans, Hyundai's. - I am missing 30-40 more.
