Just picked up my first Corvette a couple days ago, it's a 98, higher milage (223k) but engine and trans were replaced with new at 213k. I'm getting a p1860 code for the TCC PMW solenoid, before I take it to a shop I plan on doing some electrical troubleshooting but figured I'd ask here for previous experiences. The code only seems to show up when I am just sitting parked or driving at lower speeds, I drove 110 miles on the highway running 70-85mph and the light never came on until I slowed down and stopped to turn onto my road. I can clear the code and it shifts just fine, but when the code comes back it does slip just a little, as soon as I clear the code it shifts perfectly. This is why I was thinking it's an electrical issue but wanted to ask people with more experience what they thought.

I'm waiting on approval for the corvette forum so I figured I'd start here.
