I am having similar problems. When climbing hills, the vehicle starts to jerk around 40 mph. Also when going downhill, utilizing the manual downshifting does not seem to hold the vehicle back.
 
Did replacing the transmission fix your problems? Thanks!

Jeep Commander Problems by CommanderCrap

Is anyone having a problem with the commander hesitating at low RPMs which alomst feels like it's stuck between gears and the engine doesn't know whether to down shift. You can hear what appears to be engine noise when this happens and also feel vibration. The noise sounds liuke the engine is sucking air or not getting the right air / gas mix. I do not have a check engine light on or any other sgnal telling me something is not right. Any help would greatly be appreciated!

You have left out lots of information...year, which engine (and which trans); 4x4 or 4x2, how many miles, cold weather, snow, etc.
 
However, assuming it's a 3.7 L like mine (which is a 2006), you might be describing the "feature" which limits the slippping of one or more tires, by 1) automatically applying the brake to the slipping wheel(s) and 2) lowering engine RPM. The noise you are hearing may be the brakes being applied. The engine slowing would make no noise, but it would mean that your foot is not controlling the throttle...it is being computer controlled. This is supposed to avoid making you spin out of control on wet roads, snow or ice. OR...
 
You could be describing a cold engine/trans symptom that I have encountered only once, when it was -6 in Chicago last month and the engine/trans had not warmed up for more than a few minutes. This I indeed attributed to the possibility of foul gasoline and I put a bottle of Fuel Injection Cleaner in the tank. I have not encountered the problem since and it has been darn cold.
 
So far I really like my Jeep. It is very sure footed in the snow. Much more so than my old Suburban.

Sorry for the missing info! 3.7 4x4 2006. Thanks for the suggestions, but this is not traction control or antilocking brake symptoms. This has been happening for a while now....prior to any snow or foul weather. I am able to reproduce the problem every time I drive at 1.75 rpms and ask the car to down shift from 5 gear to 4th or 4th to 3rd. The transmission seems to get stuck for a few seconds which causes slight bucking and vibration. I did try some fuel additives to rule out clogged fuel injectors or bad gas. I've given up and will take it back to the dealer tomorrow. I will let you know what they find.

i know you posted this message a long time ago, i am just curious if you remember what they replaced to get the airbag light to stop coming on intermittenly. I am having problems with mine and the dealership cant figure out what is wrong. Thanks!

Front fan switch not working by jgraham058

My daughter bought a 2006 Commander and is stationed in Montana. She tells me that the front fan operation for the heat is not working but the rear is operating fine. Can you please tell me what direction to send her in finding what I hope is either a fuse or relay problem.
Thanks

I have the same problem on a 4.7L 2006 Commander. The sudden downshift seems to occur at the shift points, instead of shifting into the higher gear it shifts into the lower gear. At first the problem happened after driving about 60 miles at 75-85 mph, usually during wet weather or wet pavement with road-spray. One of the engine codes indicated an electrical short and another a speed detection problem (or something like that in the wheel sensor). The dealer replaced the transmission computer and transmission fluid all-around. The problem re-occured during the next wet weather period. Now it seems to occur randomly, even on short trips where speed never exceeds 50 mph.
 
The sudden downshifts cause passengers to nearly hit the windshield, luckily no ones ever been tailgating me and I haven't been taking a turn on wet pavement or in icy conditions - the down shift would definitely cause a loss of control, loss of traction, and an accident.
 
Shortly after the first few downshifts, I started using the slap-shift to manually control the gear settings which stopped the sudden downshifts while in manual mode. Since then I've learned that leaving the slap-shift in 4th works fine and the trans goes through all the gears, although at slightly different shift points.
 
I can normally sense the problem about to happen when in Drive - the jeep seems to miss a shift point and the rpms increase as it struggles to make the up-shift. At this point I slap shift into 4th and leave it there - otherwise there would be a sudden downshift.
 
The dealer is useless, say they can't find a problem, and say their diagnosis is confirmed by their sending a car-hop out to drive the jeep for 15 miles with nothing happening.
 
Anyone know the fix - please post.
 
Regards,
Jim

Spare Tire Lock? by ctom
Mar 15, 2009 (3:09 pm)

I have a new '08 Commander and was hoping for some guidance on some way to lock the spare tire. There has been a rash of thefts of spares (I live in Chicago) - they cut the cable that holds the tire up. Any help is appreciated...
