The vehicle will go into drive but not reverse and it is making a whining sound.
SOURCE: 2002 Chevy SC1 1500.
Are you sure you have all the forward gears?(4speeds ,three shifts)This is a common problem with this transmission and it is almost always a broken reaction shell.The shell brakes due to a diagnostic code setting and putting the trans into a high pressure setting and braking the shell.It is possible that you have a problem n the reverse input clutches but this is rare.Eithe rway the transmission will need to be removed and diasssembled.Good luck and let me know if I can help.
