I've got a 4 speed (I think it's 4) automatic transmission, I've noticed on the cooler mornings it's a bit slow on the up-shifts until it seems to warm up. I've only had the car a few months, and the temps have only been getting into the mid 40's at the coolest, is this nothing unusual? By the time I roll out of the housing development, it's pretty much just fine, that takes maybe about 5 minutes from the start of rolling out of the garage. It's not bad, but it just seems to hang on to 1st a little long until it's warmed up. After that it's perfectly fine. I just wonder if it's a sign of maybe needing the fluid changed in the transmission and maybe a filter if there's one in there? Ferris, Ferris, anyone, anyone?
