my friend has a 98 gt with nearly every bolt on. i have a stock 04 gt and have been still beating him even more mods he puts on. Today i drove his car and noticed the 1st 2 gears are GREAT in the car, but as soon as you shift into 3rd there is a massive power loss. I pull on him in 3rd when we mess around. Could he be in need of a new tranny. He has 90k mile on it, he also has 373 gears that pop really loud with every shift during hard acceleration. Could the gears possible be installed wrong? tranny just going out? no idea i not good with workin on cars but i can drive a car pretty good and noticed the huge power difference. Not just the feel of the car bout the speedometer was barely climbing. The power is there for sure , just the pick up becomes minimal. Any help is GREATLY appreciated because lookin to fix the probelm asap. Thanks
