Help -- first to second shift

Anyone notice if when the transmission is cold it is hard to shift from 1 to 2 straight back? Seems like it wont go into gear, drops into third with some pulling and then it will go back into second. After I drive the car for a while it doesn't seem to do it?

I’m the furthest thing from a tranny expert but maybe a fluid change is in order. I do not experience this phenomenon in mine. How cold are we talking?

I assume it's not CAGS interfering, right?

Recommended changing the tranny fluid. If you have a later model C5, consider up-grading to synthetic ATF. It will make a big difference.

the only time consuming thing here is removing the console. It's not hard to do just time consuming!

Your first thought should not be CAGS if/when the OP mentions "When Cold" because CAGS doesn't come on unless the coolant temp is like 170+...

I also have this problem, sometimes 2nd gear is pretty tough to get into in the morning... I mean, i'll poke out onto the road in 1st... then pull back into 2nd, and it'll kinda pause for a second, then slowly slip in... but after the first couple shifts it goes away... and it's long gone by the time the car is warmed up...
