Slipping in 2nd & 5th

2008 G37 Coupe 5at 205k miles

I had this issue as to where my car would shift harder than usual into 2nd under hard throttle or wot. I decided to drain the tranny and replace the screen with a new one. There was no sign of any leaks. I drained almost right at 5 quarts. So I refilled with 5 quarts of the Valvoline Import MultiVehicle Full Synthetic. After doing so I made sure everything was clean and snug with no leaks. I went for a drive and it was still driving the same. Fast forward 6 months later and now it slips for roughly a second under light throttle then catches with a light jerk going into second. Also it slips for about a second then catches like normal going into 5th. Does this sound like a minor issue or should I look into buying another tranny?

Thanks.

assuming u used the right fluid the slipping could be caused by not having enough fluid in the tranny.

Check the fluid while hot after driving home from work and it was within range. I performed a quick drain and refill (4quarts out and 4 in). I also reset the ecu. For the first 10 minutes of driving it was fine then it started doing the same thing. Being that its a high mileage tranny Im looking into swapping it for a lower mileage used one.

Are all re5r05a transmissions compatible?
I have the option of getting an 04 or 05 from the junkyard at a great price.

Use the correct fluid as specified in the FSM
