what the hell is that noise??
Just got 350 miles on the car and i noticed that when i start off in first gear there is what sounds like a bad bearing rattle. very annoying to say the least. should i take it back and if so what do the cavalier/truck/blazer mechanics look for?

Sorry, completely normal.. If you do a search on the forum you'll see. Has to do w/ the design of the gear sets in the transmission.. :cheers:

Is there any way to reduce the rattle? It is frigging annoying. Has this been a common problem since the c-5 came out? if so GM should make a face like they are ashamed.

You can also stick a set of 4:11 gears in the rear end. With the reduction in effect to take off from a stand still.....you won't hear it. PLUS...your car will feel like the Sports Car it's suppose to be.

Re: what the hell is that noise?? (redbird2000)
There's not a fix to the problem, but the cause of it is a consequence of the gear design of the T-56 transmission. The gears are a straighter cut than typical to improve the torque capacity of the tranny. Kinda like the old M22 "Rock Crusher" transmissions of the 60s, but obviously a lot quieter. You'll get used to it, trust me.
BTW, this problem exists in every T-56 installation: F-bodies (can't believe GM killed 'em off :cry :cuss :banghead: ), Vipers, and those C4s that have them.
HTH, and have a good one,
Mike
