2007 Sky Automatic Transmission
We bought a Sky for my wife last December, with the standard engine and
automatic transmission. Shortly after we got it I couldn't help but notice how badly the transmission is programmed. 1. Half the time it takes off in second 2. It's really wishy-washy with the torque converter clutch 3. It up-shifts too soon, requiring a lot of throttle to keep it in gear in order to obtain a reasonable acceleration rate. 4. It feels like ignition timing is retarded in 1st as a form of traction control which makes it sluggish when launching. I like the car, but the first two items bug the crap out of me every time I drive it. I haven't taken it to the dealer yet to see just what and how much they can tweak it. I tried to order a factory service manual for it but I'm told it is not available. Anyone know where I can get a factory service manual for the Sky? After seven months and over 5000 miles I have this to say about our Sky: + Engine power is adequate for my wife. + Engine power curve and transmission gearing are well matched. + The engine starts instantly and runs smoothly. + The top is really easy to raise and lower. + It has a firm ride and handles very well. + Excellent braking. + The dash and controls are laid out very well. + The MP3/CD stereo has a good sound and is easy to use/adjust. + It is fairly quiet on the highway with the top and windows up. + Fit and finish is very good. + AC works well even at 110F - The fuel gage is hard to see in bright sun light. - The radio and message displays are impossible to see in sun light. - There are too many shiny surfaces on the dash and console which reflect sun light (top up or down). - It is very difficult to see when backing up (top up). - The transmission is slow to respond to conditions that trigger gear changes - Storage is minimal. - Gas mileage is disappointing, the worst of the three cars we own (26 HWY). -- Gyz 07 Saturn Sky 98 Dodge Status ES 94 Mitsubishi Eclipse GST |

2007 Sky Automatic Transmission
Doesn't seem to describe the transmission in our Sky at all. I was told
the Sky has a French transmission, not German. I am French and German and don't like either. > The Hydra-Matic 5L40E/50E automatic transmissions have some unique > operating characteristics with which customers may not be familiar.

Our transmission feels like it was programmed to mimic a CVT, not a manual. > -Normal Mode Operation > During normal mode operation, drivers may notice increased powertrain > braking after releasing the accelerator pedal... Our Sky takes 7 seconds to initiate engine braking on the highway -- another very annoying characteristic. > -Sport Mode Operation > Typically, Sport mode delays upshifts.

It takes 50% throttle to get it to upshift at a decent RPM. > -Driver Shift Control (DSC) > The driver manually overrides the automatic gear selection.

The one feature missing is torque converter clutch control. If it had that then it would be the perfect automatic transmission (for me). What's funny, when Dodge first introduced the Auto-Stick in 1995 all of the car magazines slammed them and dismissed the feature as lame. What car manufacturer doesn't offer this feature now? If Dodge does it, it's crap; anyone else, it's golden. BMW 7 series transmissions are to be rebuilt at 100,000 miles and that's acceptable. If a Dodge transmission fails at 120,000 miles, it's crap. Mine has over 137,000 miles on it without having to rebuild anything (knock on wood). > -Adapts > Adapts continually compares actual shift times to desired shift times... The shift pattern hasn't changed from the day we drove it home. All of this sounds nice, but in reality the TCM & ECU are guessing what the driver would want based upon conditions, and too often guesses wrong (like Microsoft & Windows). I say forget all this stupid BS and give the driver the option of commanding the car -- what a concept! -- Gyz 07 Saturn Sky 98 Dodge Status ES 94 Mitsubishi Eclipse GST |

I would love to get my hands on the equipment to reprogram the transmission in this car, then develop a performance upgrade package. I'd bet it would sell! Gyz |
