2001 XE 2.4L Automatic

Transmission slips for about 5-10 secs when I put it in drive while cold. Doesn't happen in reverse or 1st, just drive and 2nd.
Changed the transmission fluid and filter about 200 miles ago but it didn't seem to change anything.
No signs of metal shards or anything else to suggest serious damage in the pan/old filter.
Fluid level is fine.
Not sure if related or not but it shifts a little hard from 1st to 2nd, but it gets better after about 20 mins of driving.

Any ideas on what could be causing this?

How many miles? Do you know if tranny was regularly serviced?

It could be the piston seals in one of the drums has hardened over time. When this happens, they don't seal well when cold and stiff but can start working after they warm up and become more pliable. A line pressure and stall test would be recommended to diagnose the problem, but, if it is the seal or a problem with a clutch assembly, it will require teardown of the transmission to fix. At that point, it would make more sense to overhaul the transmission or replace it. Otherwise, you might try using a conditioner like Trans-X and keep driving it until you have to do something about it. The factory service manual will give you a symptom chart that will list all of the possible causes for your concern and the fixes in order of most likely to least likely.

only had it for a little over a month, but the guy who sold it to me had a tranny flush a few months ago. The fluid was pretty brown when I changed it though so I'll drain and fill it again when I get the chance.

If it was a seal wouldn't it still slip when I shift to 1st? Sorry don't know too much about the inner workings of transmissions, just really hoping it doesn't come down to that.

Not necessarily; it depends on which drum piston has the hardened seal. You have several clutch assemblies within the trans, each one consisting of a drum, piston, friction plates, steel plates and a retaining ring.
