If it is in high gear, it is locked up at one to one so it doesn't make any difference to the tranny how fast you are going. This is because as far as it is concerned, it is all done shifting, and is just along for the ride.
If you suspect your PowerGlide is unreliable the time to change it is before you are left stranded on the side of the road. Across town or just down the street the wrecker is going to charge you the same fee to hook up no mater where you break down. It is like a taxi ride the biggest hit is in hailing the cab not in the mileage (which has gotten very expensive lately).
I have been a member of AAA for decades because not all of my hot rods are as reliable first time out as they should be (I make mistakes like any one else). In addition to maps (which has lost a lot of its appeal since Google allows you to print your own Trip-Tick) I have a 100 mile bonus tow so the hook up and the mileage is now pre-paid. I also added my RV to the package after I broke down once with my brand new store bought truck and discovered they would cheerfully tow my truck back to the Chevy dealership of my choice, but the trailer I was pulling at the time had to stay where it was on the side of the road, as that wasn't covered under the agreement. With RV coverage they take everything, truck and what ever it is towing, any where you want. And by the way that includes my actual Winnebago motor home that requires a semi to move.
First time that The Winnie breaks down I will have paid for my AAA membership for about five years on that one call.
Much rather have a AAA wrecker that is inspected and insured to be sure it has all of the equipment needed to safely tow your vehicle than have Joe's Garage and Salvage show up with a 1987 three quarter ton truck with a hand made steel boom attached to the floor board and a winch off a 4x4 to lift your car by the bumper on a single hook. Just imagine the damage as it sways on the end of the hook ramming into the back of his "Wrecker" on every stop.
Just a thought.
