2012 Jeep Liberty 4-speed

Why would Jeep put a 4-Speed automatic with a V6 in an SUV? Doesn't make sense

Because they're Jeep, that's why. Old ways.

What engine/transmission combo would make sense in your opinion?

Why did you get it if you thought it didn't make sense?

Re: 2012 Jeep Liberty 4-speed

I like the V6 thats in it, and I dont have a huge problem with a 4-Speed, I just don't see why that would be done.

I think a 5-Speed Auto would be ideal

Near the end of the year Jeep will have an 8 speed. »carscoop.blogspot.com/2012/03/ch···d-8.html

Until then they're stuck in the 1990s.

Not for the Liberty. The Liberty will be overhauled by Fiat.

They already are under the aegis of Fiat but they haven't done nearly enough to revive the brand. An SRT GC with a Hemi and an 8 speed auto might help.

Jeep Is Back On The Road Under Fiat
Piggy-backing on the Grand Cherokee are substantially refreshed versions of the Jeep Compass and Patriot, and nicely improved versions of the Liberty and Wrangler. These upgrades were funded and executed largely under Fiat's control, and point to signs that the Italians have a much greater understanding, appreciation and commitment to Jeep than the Germans or Cerberus ever had.

Why would Subaru offer a 4-speed auto in the WRX? Or Toyota offer a 4-speed auto in the Yaris?

I'm guessing they are waiting on the next powertrain overhaul to make the switch so they don't have to go through EPA certification just for a trans change. To Jeep's credit, the 5-speed auto in the Cherokee is actually a 6-speed and has been used since 1999. How many other automakers had 6-speed automatics back then?

Seems most of them just started making the change in the past few years. GM still has some 4-speed transmissions in a few vehicles also.

In cars it seems more practical

I would disagree. The smaller engines and narrow torque range could benefit from a gear or two more to keep the engine in optimum operating range.

Example.... Anyone ever recall driving a 1st gen Ford Escort from around 1988 or so with the 3 speed auto. Perfect example of how fewer gears suck. The RPM spread between gear changes was huge. Would drop from about 3800 to what seemed like 1200 rpms between 1st and 2nd and way out of the power band. Awful....

Had this been a pickup truck with a torquey V8 you probably wouldn't notice as much. Similar to the V6 in say the Liberty?

That makes no sense. Why would you put a 6 speed auto in a car/truck and then lock out one of the gears. That makes 0 sense.

I'm old enough to remember the Powerglide trans in the Chevys. My dad had a '59 Impala with that trans with a 6 cyl. It sucked!

The more gears the merrier.

They didn't really lock it out. All six gears are used. They use two separate 2nd gear ratios. They designed the other 2nd gear ratio to be used as a "kick down" gear when passing. Sometimes the tradional 2nd is too low for passing and 3rd may be too high. The alternate 2nd ratio is in the near perfect spot for a pass and a quick upshift to third....

Actually works pretty well.

because they want it to be different. They think they can sell more of that with that feature.

The reason you still find a 4 speed auto in the Jeep Liberty is because it is rumored that Jeep will be stopping production of that model over the next 2 years and as such are not going to invest the large sum of funds that would be needed to update it with a more modern power train.

Back in January i bought a 2012 Liberty with the 3.7 V6 for my wife as a replacement of her Saturn Vue. Wile the power train of the Vue was superior with the honda designed 3.5 V6, overall she likes the car and the 4 speed tranny seems to be more then adequate. I had also considered the small SUV wannbes from Chevy and ford, but equally equipped, the Liberty won hands down in out the door purchase price.

I drive an 09 HHR with the 4 speed auto and it is perfect for this car. No constant down shifting like most of them and still gets great gas milage.

If you have ever driven a Nissan product with the CVT it makes you not want to own anything else. I had a 270 horse Altima with the CVT and it was instant power with no waiting for a downshift for passing. I will admit they take some getting use to.

After driving this Liberty for a few weeks now, i don't regret the purchase
