So I'm merging onto the highway in my 98 Mirage, going about 55ish (cars all around me) when it starts slowing down. The motor is still running but I have no gears - no reverse, drive, or 1, 2. We towed it home and put in a new ATF (outside) filter and added fluid. Still nothing. When the car is not started and running, I can hear a hum when I shift to reverse or drive. What's going on? Anybody know? Do I need a new tranny or can it (please) be something cheaper? Any help would be appreciated.

 

sounds like its time for a rebuild. Internal parts are wore out. Could be the torque converter too, but my guess is its time to rebuild the tranny.
