My car is making a grinding noise when i take off on first gear and when i let off (Down shift) on any other gear but once i step on it it seems to run like a champ i thought it was my exhaust being loose. Is my tranny going out.??? its a 92 si with 210239 mi on the chassis dnt know how many on the engine.

 

It sounds like its the input shaft bearing going out on the trans

 

its your TURBO

 

Just had the same problem.. if the noise goes away when you press the clutch.. then that is the input shaft bearing..

I tried to see if i can get fixed, but it's cheaper to buy a used one.. you can find here for good price

 

have you ever checked the fluid?
