Hello all. I have a 96 G20 and have noticed that it has no pick up and no power until the car is warm and it hangs in 3rd for about three miles and then finally shifts to fourth. The trans fluid was about a quart low so i topped it off but it did not help. The car revs fine in park and neutral. Just no power until warm and seems to be getting worse gas mileage than my mustang. 100 miles and Im at less than half a tank. Any thoughts??
