A friend of mine just had his TH350 tranny rebuilt and had a 2500-2800 stall converter + a 2 stage shift kit installed. He got the car fired up and put it in gear (forward or reverse) and he can take his foot off the brake and the car don't move unless he puts his foot heavy on the gas it will launch the car.If he goes easy on the gas it doesn't budge. We both have no knowledge about stall converters and were wondering if this was the way it works. He is going to give the tranny place a call on Tuesday when they re-open but i figure i'd ask for some opinions here on his behalf.Thanks
