1998 1FZ-FE 105 series New starter motor grinding noise

[slimtom]

Hi everyone,
I got a 1998 1fz-fe 105 series with automatic transmission. I took it to the mechanic to get the alternator and the starter motor changed over the weekend. After I got my car back I immediately noticed that there was a grinding noise when I start the car. The grinding noise only happens at the end of a start or immediately after the engine starts. (No matter how fast I release the key. The grinding noise is right after the engine starts). however the grinding noise stops immediately after I release the key. The starter motor is a brand new aftermarket one. Not original equipment ( The original equipment starter was out of stock) The mechanic told me because of its a new starter with new gears, it takes sometime to break in, and asked me to come back in a month if the grinding noise doesn’t go away.
I’ve done a lot of research on starter motor grinding noise over the last few days, but can’t find any reason why the grinding noise only happens at the very end of a start on an auto transmission.
Please any help would be appreciated. It drives me crazy and it’s hard to wait for a month.

I don't have any ideas about the noise. Just wanted to say you may want to post over in the 80 series thread as most of them will have the same motor as you.
