Martin Posted April 4, 2007 Report Share Posted April 4, 2007 I saw the commercial for the new Maxima's and I was wondering what is up with the new no shift shock. Is it 4 gears made to be one or is it just a lessoned shift feel. Quote Link to comment Share on other sites More sharing options...
mrblunt Posted April 4, 2007 Report Share Posted April 4, 2007 Variable tranny IIRC, no gears. Quote Link to comment Share on other sites More sharing options...
Martin Posted April 4, 2007 Author Report Share Posted April 4, 2007 so wouldn't that be bad on the gas milage because normally when your at a higher RPM it waste more gas Quote Link to comment Share on other sites More sharing options...
Guest Hal Posted April 4, 2007 Report Share Posted April 4, 2007 No gears means it would constantly adjust the gear ratio IIRC. It's not just a single gear. Look on howstuffworks.com Quote Link to comment Share on other sites More sharing options...
Dr. Apex Posted April 4, 2007 Report Share Posted April 4, 2007 It's called "CVT" or continuosly variable transmission. It uses some type of belt/pulley system to constantly adjust the transmissions speed with the engines. A friend of mine drove a car with one recently and said it was wierd, the engine was always at the same speed depending on the pedal position but it never shifted, just constantly accelerated.

Joe Posted April 4, 2007 Report Share Posted April 4, 2007 NO belts, No pulleys if its like the Lexus CVT. I cannot remember the name for it, but its basically two sun gears, two sets of planetary gears (like in an auto trans) and the capability to hold both, one, or none. It pretty much changes gear ratios constantly. I believe as input shaft speeds up, it can slowly start to apply the gearing to allow a numerically higher ratio then apply more and more until eventually arriving at an overdrive ratio. My lazy ass isnt going to get my CVT manual either! Its designed to keep the engine at torque peak all the time during full throttle acceleration, or anywhere below that in proportion to throttle input.

2 Sweet Posted April 5, 2007 Report Share Posted April 5, 2007 That would really fuckin bother me to never feel my car shift. :nod: 100% agree. I read up a little on that whole CVT thing a while back. Interesting concept but no way would I want it, it just seems goofy to me. Quote Link to comment Share on other sites More sharing options...
Stanello Posted April 5, 2007 Report Share Posted April 5, 2007 I would LOVE to have a CVT transmission. What's wrong with keeping your engine at peak power under full accel? I know my car would be a hell of a lot faster. Quote Link to comment Share on other sites More sharing options...
thorne Posted April 5, 2007 Report Share Posted April 5, 2007 I can't see those transmissions taking to mods very well. I've ridden in the nissan suv that has it. Just fucking wierd. Quote Link to comment Share on other sites More sharing options...
TTQ B4U Posted April 5, 2007 Report Share Posted April 5, 2007 Can't be any worse than the ones in our W-Bodies Not feeling it shift or shifting it myself....that would be weird. As long as it hauls ass though.......not sure how it affect performance. I can't see those transmissions taking to mods very well. I've ridden in the nissan suv that has it. Just fucking wierd.

1Quik7 Posted April 5, 2007 Report Share Posted April 5, 2007 i'd have to imagine that if you blow the tranny with one of these things that it'd cost 3x as much to fix... Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted April 5, 2007 Report Share Posted April 5, 2007 I've also never heard of one rated for mor then a few hundred hp. I have heard that there is a static and immediate procedure for destroying the transmission. Try it on a test drive. Quote Link to comment Share on other sites More sharing options...
SpaceGhost Posted April 5, 2007 Report Share Posted April 5, 2007 I thought there was a 1000+ white poopra that has a CVT that fucking flies. Or is that a power glide? I'm cornfused Quote Link to comment Share on other sites More sharing options...

MrMeanGreen Posted April 5, 2007 Report Share Posted April 5, 2007 The Ford POS I drive has one, and I hate it. Like a big, fucking rubber band. That being said, there is shift shock. Quote Link to comment Share on other sites More sharing options...
