I put my RX300 in reverse but it wouldn't move. It will move

Customer Question

I put my RX300 in reverse but it wouldn't move. It will move forward but not back. I had it towed to my mechanic and it happened to him too. However this morning it started working fine as if there was never a problem?
JA: Will the headlights turn on? Is the battery fully charged?
Customer: yes
JA: What is the model/year of your Lexus?
Customer: 2001 RX300
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: No, I took it to my mechanic, he assumed something broke within the transmission, however today everything is working fine and when he ran a engine check everything came up fine.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I don't think so, I just want to know what might be going on. Just because the car seems to be running fine now, I don't want to be out somewhere and have it happen again.

Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 19 days ago.

Here’s the sequence of events I follow:
Check fluid level and color. Make appropriate repairs.
Check shift solenoids with a scan tool in bidirectional mode if
applicable. Shift solenoids are inside the transmission and this is
the easiest way to check them.
Drop pan and inspect for excessive metal shavings inside pan.
Check valve body and clutches visually.
Hopefully you may not have to go this far, maybe you just were a
bit low on fluid.

Thanks, Ron
