Regal ls transaxle problem



I was driving, stopped at a light and when the light changed my car acted as if in Neutral… put in 2nd and it went… parked it and started it again… checked fluid, disconnected battery and nothing. It goes into R fine… skips D and 3 (can’t feel anything) then catches 2 and 1 fine…

When I pull the transaxle fuse, under the hood, it catches all gears but has no power… the car moves FWD (with fuse removed) the engine revs high but the car barely moves… replace fuse and the car skips D and 3 again…
