ah, thanks... I actually have the correct one then (TX779 for the driver's side)... Time to swap it before my old one fails (and you know when they do, they take out everything in the neighborhood as well...). Curious to see if it gets rid of a whining noise for the past year and a half, that I have yet to figure out its source. My best theory was something in the trans, with another theory possibly in the rear, a pinion bearing maybe (though I tore it open and found no metal glitter in the lube, replaced it anyway just for the hell of it)... Sometimes it sounds like it's coming from the rear, sometimes from the front, sometimes in the middle... no idea. When I used to be a mechanic, we had these mics we would attach the the underside of the vehicles, that I'd drive around with to try and locate the sound... those were never very conclusive either, sounds in a vehicle are a bitch to locate sometimes as it vibrates and travels all over the chassis. Would be awesome when I replace this and the sound goes away, but I bet it won't. Keeping my fingers crossed!
