Thx for the responses. I'm talking about moderate hills, like going over an overpass. I'll be in cruise at 110kph at 2200rpm and it instantly goes to 3000rpm. Feels like the kickdown is a lot more sensitive in cruise control. Engine is allowed to work a lot more out of cruise before a downshift occurs and out of cruise it'll go to 4th(2600rpm) and not directly to 3rd. This is with an unloaded car.
Does anyone know if the cruise control is adjustable? I've had manuals before and the inclines I'm talking about wouldn't be long or steep enough to require a downshift.
