Driving with the AT kickdown rod disconnected?

I just got done with a head gasket repair on my '88 Dakota. I’ve got the engine running, but haven’t moved it yet.

In the course of the repair, the AT “kickdown rod” disconnected from both the transmission and throttle. Trying to “thread” the rod back over the bellhousing is frustrating, and I’m inclined to let a pro do it.

My question: will the truck be drivable 3 mi to the shop? What will be different if I choose to drive it?

It will up-shift very quickly, possibly lugging the engine…Just downshift it manually (with the gear selector lever) if that becomes a problem…
