Default 1977 L82 Shift question

Gentlemen,

1977 L82 TH400 3:55 rear 109,00o miles, I've had it 6years and put 22,000 on it.

As far as I can tell it's all original.

When I floor the car from a stop in 3rd the car shifts at 4200 rpms.
If I shift manually I hold it to 5000rpms. Is it normal for the TH400 to shift like this?

Thanks for any info in advance. Can't respond tonight, have to get up for work tomorrow. Eastern time.
