Engine/Tranny stutter at 40 mph

Hey, I've had this issue since I bought the car, and while it's not bad it is annoying.
At about 38 mph to about 42 mph, the engine and transmission stutter. Like there's a little lag, then a push, then a lag. Like it can't find the right gear. It's *really* annoying, but my solution is to just push the gas a little and get up to like 44, and ignore it.

Is this a common thing, or should I get the tranny looked at?

'08 GT coupe.

Thanks!

I have a 2009.5 with the 3.5l engine and auto trans and it does something similar were probably not the only ones.Mine does it in top gear while under load and while coasting. Super annoying.

Is your CEL on? (check engine light) It could be your trans or a number of other things. Your drivetrain warranty is 5 yrs 100k miles on a 08 i think. I know my 06 was only 3 yrs 36 but in 07 i think it changed to the 5/100.
