GenVibe - Community for Pontiac Vibe Enthusiasts

Hello,I just joined this site. I bought a used 2009 Pontiac vibe, 40k miles, 2.4L, 5 speed shiftable auto trans last month. I was about to put toyota T-IV fluid from the dealer yesterday until I pulled the transmission dipstick. The transmission dipstick says "WS" on it. The 09 pontiac vibe owners manual says this transmission takes Toyota T-IV. I'm confused and don't want to ruin my automatic transmission by using the wrong fluid. Does anyone know for sure which transmission fluid is correct? I've been googling for over an hour and have not come up with any concrete answers. Also, does anyone know if there is a drain plug for this 5 speed trans? there seems to be a bolt but it takes a hex wrench? My friend's 06 vibe has a trans drain bolt. Any help would be greatly appreciated

The 09-10's definitely use Toyota WS fluid in their automatic transmissions.

thanks for the info. I double checked the dipstick, it does say WS on it. I exchanged the T-IV and I bought 4 qts of toyota WS fluid. I used a torx t-55 bit to get the trans plug out. 3.5 L to refill and I just test drove the car. The vibe shifts like new now. I'm looking to get 250K miles out of this car. thanks.
