i have a 4L60E tranny in my 94 lt1. one night my friends and i went to have a little fun. after i did a really long power brake, the tranny has been acting funny. when i go from park, neutral, or reverse, it takes a while and then pops in to first. but it shifts great through all the other gears. i checked the fluid and it is the correct level. now what i'm wondering is could it be my torque converter, or did i burn my forward clutch??
