Drive Train Axles Bearings problem
1992 Saturn SC1 4 cyl Two Wheel Drive Automatic

car only goes in reverse after engine has been reved
up. Transmission makes a ratteling/grinding noise in
reverse and park after car has been in reverse.
car acts normal in forward and does not make above
sound when put into park after being in drive.
brakes are good and c. V. Joints do not appear to be
the problem because noise is coming from tranny.
Do you
have the same problem?

If u have to rev it up to get into reverse then u ethier a pressure problem in the transmission like a bad pressure regulator in the valvebody a leaking 2nd gear pistion because reverse uses 2nd gear clutch pack because it doesn't have it's own clutch. Or u might have a loose input shaft nut. So unless ur really comfortable pulling off the valve body air checking the clutches checking the trans pressure and may be pulling off the end cover to tighten up the input shaft nut then ur going to have to have a professionial look at it that knows saturns and doesn't just want to replace or rebuild that can actually diagnose it. If the fluids full then that's pretty much all u can do. Let me know what u find and if u have anymore questions.
