I hope I spelled the topic right.

Anyways, for all of you 6th geners who have the manulmatic option, when using this mode instead of the automatic make your car shift gears faster?????
With the outcome of a a faster acceleration????

I thought it was used for going up hills????

 

In theory you can use it to hold a gear a little longer, not really for faster shifts. In reality it doesn't matter that much because the computer will shift for you anyway.

 

If you leave it in manumatic while "flooring it" then the RPM goes a little higher resulting in slightly quicker acceleration. Also, you can downshift before a turn and be in the proper gear for optimum acceleration!

It's more about preventing unwanted shifts (holding the proper gear for, or in preparation for, a particular situation) than it is about the shifting process itself.

Even though I like and prefer the newer sequential tiptronic style shifters, truth is that they really don't add much capability that wasn't there with the old style straight line PRND(4)321 slotted shifters. The biggest advantage is that the sequential selection lets you pay more attention to driving than looking down at the shifter. There have been some gated automatics that have been nearly as easy to use as the newer tiptronics, including the 5.5G Max's shifter. Waaaaay back in high school ('74) I dated a girl that shared a '67 GTO with her mother. It was a 389 automatic with a gated Hurst shifter that was blast to use. (To this day my wife says the only reason I dated that girl was because of the GTO... not true , but I still let her think that!)

Some manumatics respond so slowly to shift requests that they are almost worthless for acceleration runs. My '07 CVT is actually pretty responsive in manual mode, but my Volvo is horrible - there is almost a full second delay between flicking the lever and any response from the tranny. In full throttle acceleration you have to call for the shift at 4500 rpm to get the actual shift close to the 6000 rpm redline. Hit the rev limiter a few times and you just flip it back into full auto mode, which flicks off perfect redline shifts every time.

 

Going thru the gears WOT in manual mode will get you 200 or 300 RPMs more in each gear than WOT in auto mode, however in manual mode if you pull back on the shifter & hold it there at WOT, you will go up to the redline and hit the rev limiter. Also if you you can lock in a gear, lets say your in 3rd gear in manual mode, push the shifter forward and hold it there, now you're locked into 3rd even if you come to a dead stop. Manual mode is also good for desending on mountian roads, the increased engine braking helps keep the speed down without having to ride the brakes, and experiencing brake fade

 

I use it to pass! There does 'feel' like a good bit of bite when I do that, vs. just punching it! I also use it to downshift coming in off the interstate!

Swee

 

Use it all the time. Sometimes from start too finish. Passing is my favorite. The fujita screems like a beast epecially when I reduce the gear and the RPM is high, people get scared fast.

 

Do you have a lot of miles on your car? If so, then do you experience any odd behaviors from the tranny because of using the manumatic so often?
*did you get my PM/package yet?*

 

eh, i just let the auto tranny do its thing. if i wanted to shift manually i would've gotten a stick.

 

Me too, if it were offered on the SL!

 

I have over 42K so far. No problems reported and I really do use it a lot. I would have bought a stick but....sometimes its more then good to let the auto do its work and not be bothered. Highway driving mostly auto, city mostly shifting. Its a great thing in bumper to bumper as I have mentioned in another tread. You shift it into 2nd gear (it goes down to 1 MPH) and constantly stay in it instead of getting the shifting and let the transmission kill itself going 1-2-3-2-3-2-1-2-1-2-1-2-3..well you know what I mean.

Dan. No I didn't get the package yet. I guess it will come tomorrow.

 

Just be careful. Just the other day I put it manual mode and tried to upshift. Well, somehow the shifter went back over to drive and I pushed it up thinking I was upshifting and threw it in neutral ! The revs were pretty high too. I then had to throw it back in drive. Oh well.

 

I did some stupid s*** like that too a while back! I was a t a stop light and forgot that I put it back into drive so, as i'm starting to drive I "upshift," or throw it into neutral and rev it to like 4,000rpm and then stupidly/quickly throw it back into drive while it's at 4,000rpm

 

Hehe, that's nothing. When I was still driving my old car (94 Plymouth Sundance), we were driving on the highway and my future-wife grabbed her purse or something and the strap got caught on the shifter (it was a straightliner) and pulled it from drive to neutral and eventually into reverse, all going 60 MPH. If you've never done that before, it's a really weird feeling to be going so fast but feeling the car decelerate quickly while applying gas... it took a few seconds to realize what had happened. The car came out OK (well, not any worse than it already was...). Scared me though.

That's another reason I really like the non-straightlined shift pattern of my Maxima... I feel that there is at least a little more proction from things like that accidentally happening.

 

Or as Nissan touts it 'gated shifter'!

 

It has happended to me awhile back. I just let the RPM fall (release gas pedal), throw it back into drive and then wait couple of secs before I slowly step on the gas again. Is that the best way to do it, I DUNNO

 

Tak trzeba robic, ale ja zglupialem i odrazu dalem gas

 

I do the same thing. I have a stiff downhill for a mile or so on my way back form work. I throw the shift into nutral and just glide that road. When I throuw it into drive, I wait a few secs for the gears to lock properly before I step on the gas. Doing this everyday saves me a bit of gas as well ( I think ).

 

Aren't you guys afraid after a year or so of doing this your transmission will start to lock up or explode????

 

Not a good idea. If you read the owners' manual of any vehicle with an auto trannie, you will see that they advise you not to coast for very long in neutral or tow the vehicle with the drive wheels on the road and the trannie in neutral.

The explanation for this is that while the drive wheels (and those parts of the trannie connected to them) are doing 50 MPH (or whatever your speed may be), the remainder of the trannie is only at idle speed. There are (or is, can't remember which) transmission fluid pump(s) connected to the idling part of the trannie that are not pumping that much fluid at those low RPMs. This starves the parts of your trannie that are going faster of proper fluid and lubrication.

Suggest you stop this practice in a vehicle with an auto trannie. I do this all the time in my 6-speed because it has no lubrication problems with this trick.
