I got a stock 700R4 trans behind a 350, and the car runs great no probs with starting, running, reving. But it seems that the power isnt getting to the ground, when im driving down the road, and step on the gas the trans down shifts fine but the wont hardly go, it'll rev to 3 grand, but the speedo hardly moves, i dont know what to do short of getting a new tranny. Any anwers would help alot. thanks
