Cruising round town and basically when under 55, I leave it in third, but does it hurt to be going 60+ and smack it into OD? And vice versa, going 60+ and dropping down to 3rd?

Built 80e and obviously none of this would happen at anything but part throttle.

Sorry don't know much about the 4L80E, but you're right it has been kind of dead around here.

Just waiting for you to calculate the shift energy.

Well there Mr. Hydramatic.

When you develop a transbrake for the 4L80E that actully works, you'll still have catching up to do. Aside from that abortion you sold to people that didn't work and was such a failure you had to change your company name.

Prob catching up on their "how to be an internet ******* 101" classes.

No problems with doing that, All that happens from manual 3rd to 4th & a 3-4 shift at the same time is the Overrun clutches have to release & O/D clutches apply, The Overruns have to release so the O/D roller clutch can overrun.

Just don't go around nailing the **** out of it in D4, All torque is routed through the O/D roller clutch in 1st/2nd/3rd, In manual 3rd the Overrun clutches are applied & keeps the stress off the Roller Clutch.
