revs more than it accelerates.? it gradually picks up speed, could it be the clutch or the transmission? ive never changed to transmission fluid. i tried getting it changed a couple of months ago at an oil change place but they couldn't find were to change it. when im on the highway going about 65mph sometimes the engine will rev harder while not picking up speed. ill have to ease off of the pedal to make it feel better. so in 1st and 2nd the engine is working harder and going 65 or above the engine works harder until i ease into it. what's going on?
