"GM shall bear a nine-geared transmission! Not four, or five, or seven, but NINE! ...which he will wield on all wretched customers, customers just like you, sir, there..." This is getting comically ridiculous. I'd rather they produce a transmission that is actually robust enough that one doesn't have to worry about it needing to be replaced @~100K miles. |

9 or 10 gears?
How big of a transmission are we talking about? If it is a FWD transaxle, there is much more limited space. How big are each of the gear sets? are they robust enough to not wear out or shed gear teeth after years of use? How often is this thing going to hunt and peck for the right gear ratio, and how much time spent shifting between 9 or 10 gears? How narrow is the engine's power band? That is the only major reason for many gear ratios. A wide power band, which the new DI & Turbocharged engines are supposed to have, should require LESS shifting, not more. How many bands, hydraulic circuits, and moving parts are vulnerable to failure, and trashing the rest of the gearbox? How much is a 9 or 10 gear gearbox going to cost to replace, or have rebuilt? My family has had all sorts of different brands of cars that have required transmission re-builds. Chrysler, Ford, GM, and Subaru. Hondas are known to have potentially delicate transmissions. CVTs from all brands have reliability issues and seem to have higher repair rates after warranty expiration than automatics or manuals. I don't trust efforts to introduce more complexity, and more un-proven parts, when they have yet to prove definitively that the transmissions are rock solid. What brand is known for transmissions that *DON'T* need repairs beyond the regular maintenance fluid change service, and are more than capable of coping with any driving style, and any amount of power than the engines put through it. |

Any car with a tall overdrive and a reasonable final drive ratio can do that.
the only thing required is enough latent torque to pressurize the hydraulics to down-shift when the accelerator is pressed. Most cars don't stay in top-gear if the driver presses the accelerator, anyway. A 3 speed automatic can do that, if the third gear ratio is ~0.65:1 or so. it is just a matter of how many gears, at what interval, are between lowest and highest gear ratios. |

Eh who cares.
Are you a CEO or engineer. No need to get upset, lots of other things in the world to get pissed off at. Quote:

In all fairness to the cesspool that is union controlled GM.
GM has always made a pretty darn good transmission. |

Why not just perfect the CVT and be done with it? Subaru already has a CVT that doesn't drone too badly and somewhat mimicks an auto if you want. Change it from six to ten and call it good .

Why is it that people ignore the thread point which is GM and Ford are both working on this 10 and 9. Surely if 9 is bad 10 must be terrible. Anyway if they can make it cheap, robust, then it is a great thing. If they can't then...

Cheap and good seems kind of a stretch.

Yeah I don't mean "cheap" so I should change the word to say something else such as.
"Cost effective" That would be a better term. I don't need it to be cheaper or even as cheap as 5 speed alternative. Just that it pays for the gas savings quickly and will not break. Quickly like in 1-2 years. |

Numbers from AAMCO and other chain transmission repair shops showed a continuous drop in transmission replacement from 1990 onwards. I would take hard facts over anecdotal evidence. |

I'm just not sure what about this news is worthy of an angry rant. Time marches on.

Mine goes to 11..................
Honestly GM makes some great transmissions. My family has a few of them and they all did over 200K with standard maintenance. I don't see how you could tow with a CVT. That must be where they are going to apply this. Also, I wonder if they will use same Allison design in the units. Peace, Greg |

The AT in our '97 Yukon was replaced 3 times before it was sold in '02.

CVTs suck to drive, have little to no mileage benefit, and are unreliable. They're the worst transmission choice you can make. I'd rather have a two speed powerglide. |

There are several things that make the new Impreza have 30% better mpg than previous Imprezas, but the number one thing is the CVT; so how does it have "little to no mileage benefit"? Subaru's Lineartronic CVT has proved to be reliable. As for sucking to drive....well....that is preference. I think they are fine. |
