I am not sure what exactly it is related to. I notice whenever car starts going uphill, it'll downshift even though the uphill grade is really small! I drove Chevy during my recent vacation in Colorado and Utah and this is where I realized the problem with my Corolla. It does the same thing in Cruise control but that might be because of lousy cruise control. Any suggestions?
doesn't seem to be any problem, the car's just trying to maintain speed (when in cruise) and the hill puts more load on the engine, that's why it'll downshift

Even without cruise it does the same. And I am talking about very gentle slopes! I guess uphill was really a wrong word there/ Fluid level is good.
Yes, i admit my english is not good, but don't mind.
What i saw for most of the American cars here, may be those are old models which have transmission problems. Most of the Dodge Caravans have poor transmissions, which hardly last over 100,000kms.
Tire pressure recommended by my toyota service centre here was 34psi for good fuel consumption, it's not my findings.
Wow 34 to 36 psi on US highways will ruin a front suspension system in 5000 miles. Seriously I did try that higher psi just to see how it felt and man it was rough riding.

"Most" is not accurate. "Some" is better. I own a 2007 Chrysler minivan, and help moderate a Chrysler minivan fan club forum. The reputation of the Chrysler transmissions is still soured today from what was going on 10-15 years ago, and even then, the reputation was much worse than the actual field performance (as it usually is).
My '97 Dakota is still on its original transmission, with 176k miles (that's over 283,000 km). My '97 Cadillac has 160k miles on its original transmission (without even a fluid change!). I've never had to replace a transmission, and every automatic transmission I've owned has been in an American vehicle.

It shouldn't ruin your suspension. It might ride coarse. Our '07 Chrysler van specs 36 PSI front/rear as the OE pressure. My '97 Dodge truck specs 35 PSI front/rear as the OE pressure.
I've run 35 PSI in the front of my Corolla before and it was fine. What got to me was the increased road noise, so I've got it back down to about 30 PSI right now. I also noticed no real difference in fuel economy, so I decided that I didn't want to pay the penalty of noise/ride.
