Hello all I have an 88 ' GXL and I went for a drive this morning for fun with the stereo turned off and I noticed that when I shift from first,second and third gear I get this sound that sounds like 'shwooo!!'. Now I know my car is not turbo charged and im aware that turbo charged cars have a blow off valve that makes this noise. I have no complaint's because it sound really kewl, but whats causing it? only thing I can think of is the new K&N cone filter I put in. Thanks for your input---Ren

 

I had a first gen that did the same thing. I think it's the syncros in the trans that make the swoosh. I have no idea why some trans make the noise.

It didn't seem to affect longevity, I put 40 or 50k on the car before the engine blew....

 

My engine (not tranny) made a swooshing sound, almost like when you blow through a ribbed staw (the oversized kind you would buy with a nondisposable cup), almost a whistling sound, it came when I reved the engine or was driving over about 2000 rpm. The engine popped about 100 miles after

 

i get the same sound too, i think its the 5th and 6th port actuators bleeding off extra air.
