2001 Dodge Ram 1500 5.9L Auto - P1740 Code: TCC or OD Solenoid Issue - Safe Highway Drive for 1400 Miles?

I'm currently experiencing a P1740 diagnostic code on my 2001 Dodge Ram 1500 with a 5.9L V8 and automatic transmission. The code indicates a potential issue with either the Torque Converter Clutch (TCC) or Overdrive (OD) solenoid. I've confirmed that the transmission pressure sensor is functioning properly, but I'm concerned about whether I can safely drive this vehicle for a 1400-mile road trip in the next few days without risking further damage. I plan to make a highway-only journey with no cargo or trailer, and I want to know if driving under these conditions will cause any serious drivetrain harm. As someone experienced in DIY repairs, I'm comfortable performing basic maintenance but am hesitant to open the transmission to replace solenoids—especially without confirmation of the exact root cause. I hope to have the vehicle professionally serviced after my 4-day trip. Any insights on whether this P1740 issue is manageable during a short highway drive would be greatly appreciated. Thank you, Rudy R. Griego.
