Re: Re: Re: Why is my 4L80E shifting weaker?I've been at work all evening and my truck is with dad. He's been working on it today while I'm working, since he's off today. Exchanged my throttle body with a used one, made no difference. MAP sensor was only $52 from Advance, so it now has brand new MAP sensor on it too.....made no difference. Maybe it's the damn computer. This truck has never been wrecked, I take good care of it, and it is in excellent shape under the hood. Wiring harness is still factory wrapped and taped up tight, and nothing is noticeable in terms of wires being loose, broken, or anything else.Is there a separate throttle positioning sensor? Or is that basically what the throttle actuator control module is that's on the throttle body itself?
