As soon as we started getting this cold weather here is western PA my car doesn't downshift like it usually does......it stays right above 3k rpm's longer than it normally does and then downshifts late and the same thing when it is right above 2k and then downshift to about 1500....i was wondering if this was a result of the cold weather or something else, possible the timing belt? Sometimes it feels like im stuck in that lower gear
i have an automatic

thanks for any input.....

it just started happening when the weather turned and even when the car warms up it still happens most times

You mean it is delaying the UPshift? Like delaying the shift from 2->3? Or is it being slow to DOWNshift, won't easily kick down from 3->2?

I'm pretty sure that is normal for cold operation. Some cars, like a '92 Camry for instance, won't even let you have the last gear (overdrive) until the coolant is up to a certain temperature. The higher revs help the car warm up faster. If it is doing it after it is warmed up, then you may have a problem. I guess I'm not sure if my A4 does this. I kind of baby it when it's cold anyway.

I drive it real easy until it warms up. I try not to rev it too high until the oil starts to warm up a bit. I let it shift as early as possible by using minimal throttle input. I keep the revs under 2500 or so until the oil pressure starts to relax a bit and the coolant temp gauge starts to move. Basically, once I get heat in the cabin, lol.
