POORLY SET-UP TRANSMISSION SHIFTPOINTS

Our '06 hemi Commander gets poor gas mileage. One cause is that it will not shift into final overdrive below 72 MPH.
The dealer checked 3 other Commanders on the lot and they
shifted in at 64/66 MPH range. Since most people do not
count the up-shifts they are not aware that they are not in overdrive. For sure my wife had no idea and still doesn't really care. She loves the car. I think it is a pig. I found the problem because the RPM/MPH ratio was so high.
Chrysler says that the learning (idiot) transmission can not be changed and are satisfied with their incompetence.
I suggest that you watch the tach for a "drop" to make sure
that you are actually in overdrive.

My Commander goes into overdrive well before 72mph. In fact, it goes in well before 60mph. One thing to watch is that most cars will not go into overdrive until the engine has reached proper operating temperature. When you travel on the highway, is it normally shortly after starting your vehicle? If so, what you may be experiencing is a shift to overdrive once the Commander has warmed up. If anything, I think my vehicle goes into overdrive a little prematurely. Good luck!

i have a V8 and it gets terrible gas mileage. I fill up every five days. I did my own calculation when I first got the SUV and i got 13 mpg when i did all of the calculating. i got rid of our yukon xl because of the gas mileage, but i feel like we are getting worse

Is my average with the 4.7L V8. Currently at 25,000 miles
A little worse than my 94 GC with the 4L straight 6, but I wanted the higher towing capacity.

Hi all,
I recently bought a 5.7 hemi commander used with 4700 miles on it....I love my commander, but I too only avg 12.5 MPG and i drive 80% freeway. I thought my tank held 21gallons, but it doesn't seem like it. I thought I might have a lemon, but it looks like their ad was false..I can't ever imagine getting 18 MPG. Please contact me if anyone has good ideas.

Sorry Drez....you got suckered just like the rest of us...great vehicle.....crappy milage.....I found that if you slowly accelerate up to 62 mph on the highway (keeping the RPMs under 2000 as you come up to speed, and then maintain the speed between 58 and 62 without going out of that range for a long period), you can get the mileage up (keep in mind that the multi-displacement system will kick in during a very very very limited range). I have already tried the lemon route and Chrysler won't acknowledge it saying that they do not have the equipment to test mileage use and that the engine is working to perfection. They only publish what the EPA (an independant agency) reports. Good luck and if you want any further info don't hesitate to write

I have yet to get as much as 10 mpg in the Commander. It is very disappointing, and despite loving the vehicle generally, I now wish that I had purchased something else. The 14 mpg that I get in a Dodge Ram 4x4 with the Hemi blows away the Commander.

I recently purchased the 2007 commander with th 3.7 v6. I too feel mislead. The sticker was 16/20. Real world driving yieled about 13.4mpg. I am trying a k&n air filter. It seems to be working (according to the real time avg on the computer) but I will repost to confirm results on next fillup (currently looking like 15.5+mpg).P.S. I traded in my 02' Ford Explorer Sport 4.0l v6 which no matter how hard i drove rarley dipped below 17mpg and easily got 20-22 on the highway at 60mph-70mph+. I did not even think I would have a problem going with a newer smaller 3.7l engine. (J.E.E.P - Just Empty Every Pocket)

Has anyone else had any success increasing mileage using a K&N Filter?

I have the 06 Commander 5.7 Hemi. Using different gas types I have found the Shell VPower to give the 18 to 19 miles per gallon highway. I do a lot of highway driving on a daily basis, 30 miles each way to work and at least three times a year drive from NJ to FLA. The drive to NJ/FLA I can even inch out 20. Local I am looking at 14 mpg. I have definately found the type of gas used helps. BP I get the worst mileage.
