H1B transfer initiated before I-94 expiry

Can I join new employer after Aug 31st 2021 like in Sep 1st week, by then my current I-94 would have expired but H1B transfer is already initiated? I am worried about the possible few days gap between I94 expiry and H1B transfer approval with new employer.

There should be no issue as you have both, a timely filed extension of status and change of employer petition before the expiry of your current I94. You can start with new employer once your I140 complete 180 days.
