I have a 97 grand prix gt... It seems mostly when I take a sharper left turn from a stop and accelerate, I lose power to the wheels and it revs like its in neutral, and then catches and almost kinda slams back in.. Also notice it under a hard acceleration. The tires will spin, and I loose power it revs and slams back and I can accelerate normal. The trans fluid level seems okay. Other than that the trans seems to shift into all gears fine. Any ideas on what it could be would be great, Thanks!
