Thank you for your replies.
The transmission was serviced, and we picked up the car. Now it is shifting roughly into first gear, AND overdrive.
Before the car was taken to a mechanic, there was a hard thump when coming to a stop in reverse. It did that for a day, then stopped. Hasn't done it since.
I find it strange that after the mechanic reset computer codes he took it for a test drive, and then said it was no longer shifting roughly. Then it started doing it again after replacing gasket, intake manifold, and servicing the transmission.
The service engine light is on (has been). The mechanic had said he fixed that---was a broken wire. Evidently not the case. (He had to go out of town when I picked the car up, so I didn't get a chance to talk to him. Will do so today.)
Wish the car was paid for so my son could get rid of it.
Thanks!
