92 auto trans slipping

The car worked fine before it was parked for a month or so and now the trans is slipping bad. If you rev it up the car will creep foeward or reverse. Seems like low fluid pressure, before I drop the pan and change filter I was wondering if this could this be an electronic issue?

Did you check the fluid level...did it leak after being parked?

fluid level is good, it looks clean and dosen't smell burnt.
The car rolls free so the brakes are not stuck on.

:wtf: could it be the torque converter?
