ok so i have been noticing what seems like a my tranny slipping a bit, i will be driving the car and when it doesnt seem like there is alot of pressure on the car it seems to bog down. what i mean by pressure is when i get the car going and it runs through the gears (auto) the car seems to almost run out of power. what all can cause this? can vacuum lines or tuning be a problem? if i jump on the pedal it will kick the passing gear in but then seems as if it wants to just bog down... im new to this car and my first thoughts are tranny but can i be wrong? i am running high test in it which i am not sure i should be seeing how i havent done anything to tune it... oh and at no time have i ever noticed my rpms jump as if it was in neutral...
